Wu Zhu

This article is about the type of coin. For the prince of the Jin dynasty, see Wuzhu. For the Buddhist monk, see Baotang Wuzhu.

Wu Zhu (Chinese: 五銖) is a type of Chinese cash coin produced from the Han dynasty in 118 BC when they replaced the earlier San Zhu (三銖; "Three Zhu") cash coins, which had replaced the Ban Liang (半兩) cash coins a year prior,^[1] until they themselves were replaced by the Kaiyuan Tongbao (開元通寳) cash coins of the Tang dynasty in 621 AD. The name Wu Zhu literally means "five zhu" which is a measuring unit officially weighing about 4 grams however in reality the weights and sizes of Wu Zhu cash coins varied over the years. During the Han dynasty a very large quantity of Wu Zhu coins were cast but their production continued under subsequent dynasties until the Sui.^[2]

Transcriptions Standard Mandarin Hanyu Pinyin wǔ zhū Middle Chinese Middle Chinese /ŋuo^X d͡ʑɨo/ Old Chinese Zhengzhang /*ŋaːʔ djo/

The production of Wu Zhu cash coins was briefly suspended by Wang Mang during the Xin dynasty but after the reestablishment of the Han dynasty, the production of Wu Zhu cash coins resumed, and continued to be manufactured long after the fall of the Eastern Han dynasty for another 500 years. Minting was definitively ended in 618 with the establishment of the Tang dynasty. Wu Zhu cash coins were cast from 118 BC to 618 AD having a span of 736 years, which is the longest for any coin in human history.^[3]

Western Han dynasty

 

A Wu Zhu (五銖) cash coin issued by the Western Han dynasty.

"Wu" means "five" (5) and zhu was an ancient Chinese unit of weight equal to 100 grains of millet. A "five zhu" cash coin would weigh about 4 grams. Originally Ban Liang cash weighed 12 Zhu as a Liang (tael) was 24 Zhu, however over time the weight of Ban Liang cash coins gradually decreased so the Wu Zhu cash coins were introduced as a new standard unit (after the earlier San Zhu, or "3 Zhu" cash coins) under the reign of Emperor Emperor Wu.^[4] The introduction of the Wu Zhu also fixed the standard exchange between bronze coins and gold as 10,000 bronze Wu Zhu cash coins would be worth 1 Jin of gold.^[5]

The first Wu Zhu cash coins had unfiled edges but the second series issued under the reign of Emperor Wu had them filed. In 118 BC the central government of the Han dynasty ordered both the Commanderies (郡, jùn) and the Principalities (國, guó) to cast Wu Zhu coins, these Wu Zhu coins are referred to as "Jun Guo Wu Zhu" (郡國五銖, jùn guó wǔ zhū) coins which at most have a diameter 33.3 millimetres and a weight of 5.8 grams. A notable feature of Jun Guo Wu Zhu coins is that they have a rim around the square center hole of the reverse side of them, these rims were added to prevent people from scraping metal off the coins which would reduce their value. Another notable feature of these early Wu Zhu's is that they tend to have edges which are unfiled, making these cash coins to generally have rough circumferences, they are notably also heavier than later cast Wu Zhu's.^[6] In 115 BC Emperor Wu decreed that all Wu Zhu cash coins should be cast with a value of 5 cash coins, these coins are known as "Chi Ze Wu Zhu" (赤仄五銖, chì zè wǔ zhū) or "Zhong Guan Chi Ze" (鍾官赤仄, zhōng guān chì zè) because of their "red" or "purple" edges as they were filed which resulted in the colour of the copper being visible, another feature of these cash coins is that the "Wu" (五) character tends to be composed of some rather straight lines.

Starting from the year 113 BC, the central government regained the exclusive authority to manufacture coinage, from this point Wu Zhu cash coins started being produced by the Three Offices of Shang Lin (上林三官, shàng lín sān guān). These Wu Zhu coins had a nominal value of one coin as opposed to the Chi Ze Wu Zhu's which had an unrealistic nominal value of five. The majority of the Shang Lin San Guan Wu Zhu's contain a raised line above the square center hole on the obverse side of the coin.^[7]

Under the reign of Emperor Xuan which lasted from 73 BC until 49 BC the Wu characters were less in size and notably was written with slightly crooked strokes that don't extend to the horizontal lines of the top and bottom ends. A number of these Western Han dynasty Wu Zhu cash coins also displayed dots which represent "stars" and crescents which represent the moon on the interior rim of the coin as well as other symbols which were considered to be auspicious being some of the earliest examples of cash coins used as Chinese amulets and charms.^[8]

In the 123 years after 118 BCE, when Wu Zhu cash coins were initially introduced, over 28 billion coins were cast for circulation.^[9][10]

Xin dynasty

Main article: Ancient Chinese coinage § Wang Mang

After Wang Mang had overthrown the Han dynasty with his own Xin dynasty he wished to displace the Wu Zhu currency of the Western Han dynasty,^[11] owing, it is said, to his prejudice to the "Jin" (Chinese: 金; pinyin: jīn; literally: "gold") radical (釒) in the character zhu (Chinese: 銖; pinyin: zhū) of this inscription, which was also a component part of the character Liu (劉), the family name of the rulers of the House of Han, whose descendant Wang Mang had just dethroned. He introduced a number of currency reforms which met with varying degrees of success. The first reform, in AD 7, retained the Wu Zhu coin, but reintroduced two versions of the knife money, during a later reform the Wu Zhu cash coins were completely abolished and Wang Mang placed the death penalty on anyone who dared to circulate any Wu Zhu cash coins, but as the new currency system introduced by Wang Mang was chaotic and confusing to the people they kept secretly circulating.^[12][13][14]

Chengjia

The Iron Wu Zhu's of Chengjia, which resemble the Western Han dynasty Wu Zhu coin, is attributed to Gongsun Shu, who rebelled in Sichuan in AD 25, and issued iron coins, two being equal to one Jian Wu Wu Zhu (Chinese: 建武五銖; pinyin: jiàn wǔ wǔ zhū). Head of the zhu component rounded. Typical of Eastern Han Wu Zhu's. In AD 30, a ditty was sung by the youths of Sichuan: "The yellow bull! the white belly! Let Wu Zhu cash coins return". This ridiculed the tokens of Wang Mang and the iron coins of Gongsun Shu, which were withdrawn by the Eastern Han Emperor Guangwu in the 16th year of Jian Wu (AD 40). The Emperor was advised that the foundation of the wealth of a country depends on a good political economy, which was found in the good old Wu Zhu coinage, and so reissued the Wu Zhu cash coins.^[15]

Eastern Han dynasty

 

An Wu Zhu (五銖) cash coin from the Eastern Han dynasty.

After the fall of the Xin dynasty the production of Wu Zhu cash coins was resumed. After the restoration of the Han dynasty the production of Wu Zhu cash coins was first resumed under Emperor Guangwu who reigned from the year 25 until 56 AD.^[16] Under the reign of the warlord Dong Zhuo (董卓) the capital of the Han dynasty was moved from Luoyang to the city of Chang'an (modern day Xi'an) where he ordered that the large Qin dynasty era bronze statues which date to the reign of Emperor Qin Shi Huang be melted down to make small cash coins, large quantity of these Wu Zhu coins were so small that they were commonly referred to as "goose eye coins" (鵝眼錢, é yǎn qián) or "chicken eye coins" (雞目錢, jī mù qián) by the people. As these cash coins were so diminutive in size only left half of the wu (五) Chinese character and the right half of the zhu (銖) Chinese character fit on these coins. It is also pivotal to clarify that these cash coins are not what is referred to as "chiselled rim coins" (鑿邊錢, záo biān qián) where regular size Wu Zhu cash coins had their insides cut out so as to form two separate cash coins. "goose eye Wu Zhu coins" or "chicken eye Wu Zhu coins" were actually cast in this diminutive manner as evidence by the remnants of the metal sprue (or stub) from the casting process are located at the rim's five o'clock position of "goose eye" or "chicken eye Wu Zhu coins".^[8]

The Three Kingdoms

 

An Wu Zhu (五銖) cash coin issued by the Kingdom of Shu recovered in Sichuan.

The Three Kingdoms period was an era in Chinese history that lasted from 220 until 280 and was characterised by a period of disunity following the collapse of the Eastern Han dynasty.^[17] The Kingdom of Shu Han was founded after Liu Bei seized control of the city of Chengdu, immediately after the city was taken Liu Bei had discovered that the treasury was completely empty which meant that he didn't have the funds for his military expenses, this was paired with a severe shortage of copper, this severe lack of copper was so bad that it is said that in order to manufacture cash coins even the hooks which were used to hang bed curtains were melted as the government desperately needed the metal. cover the state's expenses Liu Bei ordered the creation of Zhi Bai Wu Zhu (直百五銖, zhí bǎi wǔ zhū) cash coins which had a nominal value or one hundred regular cash coins. Unlike the earlier coinage of the Xin dynasty which disastrously failed due to the extreme disparage between the nominal and intrinsic values the coins of the Kingdom of Shu Han weren't as badly received due to the fact that the Wu Zhu cash coins produced by Dong Zhuo only weighed around a single gram, previously a cycle plagued Chinese governments trying to set of a fiat coinage system where first the government issued new (fiduciary) cash coins, then the government would set values, usually the people don't accept these set values, and then finally the currency doesn't trade which causes inflation to set in and counterfeiting becomes a prominent problem. Zhi Bai Wu Zhu's are usually divided into "thin" and "thick" types depending on the thickness of the cash coin.^[18] It is also believed that the Kingdom of Shu Han under the reign of Liu Bei cast a variant of the Wu Zhu cash coin which had a rim around the square hole that is 21.7 millimetres in diameter and has a weight of around 2.3 grams and due to this associated is known as the "Shu Wu Zhu" (蜀五銖, shǔ wǔ zhū) cash coins, but due to later archeological findings this isn't taken with absolute certainty.^[8]

In the Kingdom of Cao Wei which was established by Cao Cao in 220 it is believed that only Wu Zhu coins were cast, moulds have been found dating to this period and it is confirmed that Wu Zhu cash coins were cast from the first year of the Taihe period (227) until the second year of Xianxi period (265).^[19]

Jin dynasty and the 16 Kingdoms

Under Sima Yan China was reunited for a short period of time under the rule of the Western Jin dynasty ruled from Luoyang. The Chinese economy improved under Jin rule and although no historical records mention the production of coinage under the Jin as the quantity of old Wu Zhu cash coins from the Han Dynasty that were still in circulation would not have been sufficient it is likely that the government would've had to cast a large number of cash coins in order to need the demand coming from the market. The Great Dictionary of Chinese Numismatics claims that Wu Zhu cash coins were being cast in the city of Chengdu in the Shu region of the Western Jin dynasty (which lies in modern-day Sichuan).^[20] After a family struggle within the Sima family caused a devastating civil war, China was so weakened that the "five barbarian tribes" from the north started conquering territories in China and established their own states starting the sixteen kingdoms period.

Former Liang Kingdom

The Kingdom of Former Liang started casting Wu Zhu cash coins which have traditionally been attributed to the Kingdom of Shu known as "Shu Wu Zhu" cash coins, some of these Wu Zhu's have been discovered in the Hexi corridor (in current day Gansu province) which lead archaeologists to believe that they may have been cast under the reign of Zhang Gui.^[8]

The Northern and Southern dynasties

After the Eastern Jin dynasty fell the Northern and Southern dynasties period commenced in the year 420. In the Southern dynasties it was customary for people to remove the middle part of Wu Zhu cash coins to create two separate coins, the portion cut out of the outer ring of the Wu Zhu is usually referred to as a "thread ring Wu Zhu" (綖環五銖, xiàn huán wǔ zhū) while the coin cut out of the inner portion is usually referred to as "chiseled rim Wu Zhu" (鑿邊五銖, záo biān wǔ zhū) cash coins or as "cut rim Wu Zhu" (剪輪五銖, jiǎn lún wǔ zhū) cash coins. Private casting of cash coins also became a common practice during the Northern and Southern dynasties period which resulted in there being many extremely small, thin, and very fragile bronze cash coins that were cast by these private mints. These cash coins are known as "goose eye" (鵝眼, é yǎn) or "chicken eye" (雞目, jī mù) coins.^[8][21]

Liang dynasty

Under the reign of Emperor Wu of the Liang dynasty there were two types of Wu Zhu cash coins which were being manufactured, some had an outside while others did not have an outside rim with the Wu Zhu cash coins without an outside rim are referred to as "Female coins" (女錢, nǚ qián).

From the year 523 onwards the government of the Liang dynasty decided to cast iron Wu Zhu cash coins due to the fact that iron was both relatively easy and not expensive to acquire in what is today Sichuan. The iron cash coins issued by the Liang dynasty are quite distinctive from other iron cash coins as they have 4 lines that radiate outwards from each corner of the square center hole which is why they're referred to as "four corner coins" (四出錢, sì chū qián). As it became quite common for the people to cast iron cash coins privately based on these government issues it wasn't long before their quantities increased so drastically that it required cartloads of these iron Wu Zhu cash coins to pay for anything, even to this day these Wu Zhu's are quite common due to the widespread private production that plagued these iron issues. After them the Taiqing Fengle (太清豐樂, "Tai Qing Prosperous and Happy") cash coin was cast under the reign of Emperor Wu, these cash coins were actually believed to be Chinese numismatic charms until recently and were named after the Taiqing period (547-549).

In 552 under the reign of Emperor Yuan the capital city was moved to the city of Jiangling, the Jiangling Mint issued Wu Zhu cash coins which had two "stars" (a term used to refer to dots on cash coins) on the observe of the Wu Zhu, one "star" was situated above the square center hole and one below and for this reason are commonly known as "Two Pillar Wu Zhu cash coins" (兩柱五銖錢, liǎng zhù wǔ zhū qián). These Wu Zhu's were nominally ten normal Wu Zhu's and are relatively rare today.

From the year 557 under the reign of Emperor Jing had Wu Zhu cash coins produced that had one "star" above the square hole and one "star" below on both sides of these Wu Zhu's which is why they are known as "Four Pillar Wu Zhu cash coins" (四柱五銖錢, sì zhù wǔ zhū qián) and had a nominal value of 20 normal Wu Zhu cash coins, but merely 10 days after their introduction they were trading at par with regular Wu Zhu's. Another variant of these "Four Pillar Wu Zhu cash coins" had the "stars" on the left and right sides of the square center hole. Today "Four Pillar Wu Zhu cash coins" are extremely rare with those that have the "stars" above and below the square center hole being the rarest.

Another variant of Liang dynasty era Wu Zhu's known as the "Three Pillar Wu Zhu cash coins" (三柱五銖錢, sān zhù wǔ zhū qián) were produced, however as no historical records mention them it is exactly unknown when they were produced, it is speculated by some Chinese numismatists and Gary Ashkenazy that they were only produced for five days in the year 557 immediately after the production of the "Four Pillar Wu Zhu cash coins" to circulate at a value of 10 normal Wu Zhu's and had three "stars" to differentiate them from the earlier "Two Pillar Wu Zhu cash coins" which had the same exaggerated nominal value. "Three Pillar Wu Zhu cash coins" have one "star" above and one "star" below the obverse square hole, while they have one "star" just to the left and touching the rim that surrounds the square center hole on the reverse side of the coin. These cash coins are extremely rare today due to their extremely short production period.

Note that despite their high nominal values, "Two Pillar", "Three Pillar", and "Four Pillar" Wu Zhu cash coins usually weighed less than 2 or 3 grams, this disparity between their nominal and intrinsic values was a contributing factor to the decline of the economy of the Liang dynasty.^[8]

Chen dynasty

 

A Chen dynasty era Wu Zhu (五銖) cash coin.

The Chen dynasty produced Wu Zhu cash coins which had a nominal value of 10 "Goose Eye Wu Zhu's" and/or "Chicken Eye Wu Zhu's" and were known as "Tianjia Wu Zhu cash coins" (天嘉五銖錢, tiān jiā wǔ zhū qián) because they were produced during the Tianjia period of Emperor Wen, however as not a single specimen exists today it is unknown how these Tianjia era Wu Zhu's looked like. It is speculated that these Tianjia era Wu Zhu's would have been relatively big and had a rim around the square center hole on the observe side of the coin being overall similar to the Taihuo Liuzhu (太貨六銖, tài huò liù zhū) cash coins. Wu Zhu cash coins that fit this description historically have been believed to have been produced during the Tianjian era (502-519) in the Liang dynasty under the reign of Emperor Wu. As Wu Zhu cash coins also fitting this description have been dug up in Guanzhong, Shaanxi it has been proposed that they might've been produced by the Northern Zhou dynasty.

Under the reign of Emperor Xuan in 579 the Taihuo Liuzhu (太貨六銖, tài huò liù zhū) cash coins were cast which originally had a nominal value of 10 Wu Zhu's but due to the fact that this fact accepted by the populace its nominal value was decreased to be equal to the Wu Zhu. Taihuo Liuzhu cash coins considered to be the "crown jewel" of Southern dyansty coinage due to the quality of its calligraphy. As the seal script version of the Hanzi character for "six" (六, liù) looked similar to a human being standing akimbo which inspired the contemporary saying that this symbolised the general people standing in this position before the Emperor and exclaiming that the nominal value of the Taihuo Liuzhu was too high. An extremely rare version of this cash coin exists that only has the inscription Liu Zhu (六銖, liù zhū), this coin is in fact so rare that only a single specimen of it has ever been reported to exist.^[8]

Northern Wei dynasty

 

A Yongan Wuzhu (永安五銖) cash coin issued by the Northern Wei dynasty.

The Northern Wei dynasty was a Xianbei ruled state under the Tuoba clan that adopted the administrative system of the Han Chinese and even established their capital city at Luoyang, a city which had been the capital city of various preceding Chinese dynasties and mandated that his people adopt both Chinese fashion and language. During this period Emperor Xiaowen ordered the issuance of the Taihe Wuzhu (太和五銖, tài hé wǔ zhū) as part of this Sinicisation process. There is one purported version of the Taihe Wuzhu which has the Chinese character "Tai" (太) written in a calligraphic style akin to that of the "Tai" on the Taihuo Liuzhu (太貨六銖, tài huò liù zhū) cash coin issued by the Chen dynasty. However, as the only evidence relating to the existence of this cash coin comes from rubbings in old coin catalogues it is speculated that or actually isn't real.

The Northern Wei dynasty started issuing regular Wu Zhu (五銖) cash coins in 510 but it is currently unknown what special characteristics these Wu Zhu cash coins had to differentiate them from other Wu Zhu's.

Emperor Xiaozhuang ordered the creation of the Yongan Wuzhu in the year 529 which was during the Yongan period (528-530), despite the fact that the authoritative power government of the Northern Wei dynasty was in trouble as the rebellion of the Six Frontier Towns waged on for a decade. After Emperor Xiaowu was forced to flee from Luoyang in the year 534 the country split into the Western Wei dynasty and the Eastern Wei dynasty, and despite the fact that neither country existed for a long period of time they both continued issuing Yongan Wuzhu cash coins to the point that both large quantities and a large number of varieties exist, as well as the fact that Yongan Wuzhu cash coins are still extremely common today.

During this era various nicknames for cash coins were given by the people which include the "Auspicious cash coins" (吉錢, jí qián) as well as the "Heavenly Pillar" (天株) cash coins, it is unknown what these cash coins were but it's speculated by Gary Ashkenazy that they were variants of the Yongan Wuzhu cash coins, according to Gary Ashkenazy the "Auspicious cash coins" were very likely to have been Yongan Wuzhu's that had the Hanzi character for "earth" (土) on the reverse side of the coin above the square center hole. The nickname would then be derived from the fact that the square center hole resembles the Hanzi character "口" and as the "土" would be above it they together would look like "吉" meaning "auspicious". According to Gary Ashkenazy the "Heavenly Pillar" cash coin may have also been a variety of the Yongan Wuzhu which has a "dot" (dots represent "stars" (星) on Chinese cash coins) in the lower right part of the obverse side of the coin. When the "Heavenly Pillar" cash coin is held upright it would point towards the sky or "heaven" (天). The "star" in this particular case can also be referred to as a "pillar" (株) because it is cylindrically shaped and appears to rise up from the surface (肉) of the Yongan Wuzhu cash coin. Another variant of the Yongan Wuzhu is also known as the "four corner" (si chu 四出) cash coin because it has 4 diagonal lines thar extend outwards from the corners of the square center hole all the way to the reverse rim of these Yongan Wuzhu coins.

There were other cash coins in this era which also had descriptive nicknames assigned to them such as "Yongzhou Green-Red" (雍州青赤, yōng zhōu qīng chì), "Liangzhou Born Thick" (梁州生厚, liáng zhōu shēng hòu), "Tight Cash" (緊錢, jǐn qián), and "Red Halter" (赤牽, chì qiān). These cash coins were mentioned in historical records and may have also been references to specific varieties of Yongan Wuzhu cash coins which currently aren't clearly identified yet.^[8]

Western Wei dynasty

 

An Wu Zhu cash coin issued under Emperor Wen.

The Western Wei dynasty existed briefly from the year 535 until 556, historical records mention that an Wu Zhu cash coin was cast during the Datong period (535-551) which had a calligraphic style akin to that of the earlier Yongan Wuzhu cash coins as well as those of the Sui Wu Zhu's. A defining characteristic of these "Datong Wu Zhu cash coins" (大統五銖錢, dà tǒng wǔ zhū qián) is the fact that they have a broad outer rim with an inner rim only by the "Wu" (五) character to the right side of the square center hole.^[8]

Northern Qi dynasty

The Northern Qi dynasty was a country founded by Emperor Wenxuan that existed from the year 550 until 577, from the year 553 the Changping Wuzhu (常平五銖, chángpíng wǔ zhū) cash coins were cast.^[8]

Sui dynasty

 

An Wu Zhu (五銖) cash coin produced under the reign of Emperor Wen.

China was reunified under the Sui dynasty (581–618). Under this short-lived dynasty, many reforms were initiated that led to the subsequent success of the Tang dynasty. The only coin associated with the Sui is a Wu Zhu coin. Emperor Wen decreed that Wu Zhu cash coins be produced in the first year of the Kaihuang period (581 in the Gregorian calendar), alongside the introduction of this new Wu Zhu cash coin the older currencies were gradually being deprecated and with the conquest of the Chen dynasty the coins now known as "Sui Wu Zhu cash coins" (隋五銖錢, suí wǔ zhū qián) were the only circulating currency in all of China. The reason why Emperor Wen introduced a new Wu Zhu was because the fiduciary cash coins of the Northern Zhou and Chen dynasties placed the economy in a bad state and the Sui Wu Zhu's were set to the original weight of 2 grams. The first Wu Zhu's are known as the "Kaihuang Wu Zhu cash coins" (開皇五銖, kāi huáng wǔ zhū) because of their year of introduction, later Emperor Wen allowed the principalities of the Sui dynasty to cast their own Wu Zhu's.^[8] Additional mints were set up in various prefectures, typically with five furnaces each. Cash was frequently checked for quality by the officials. However, after 605, private coining again caused a deterioration of the coinage.^[22] Today these Wu Zhu cash coins are still very common and must have likely been manufactured in immense numbers. The fabric of the Wu Zhu's of the Sui dynasty is unlike that of any earlier Chinese cash coins but resemble that of the vast majority of later produced Chinese coins. The rims of these Wu Zhu's tend to be broad and flat, while earlier Chinese cash coins usually have thin and rather rounded rims. The basic fabric of a coin is dictated by the minting techniques used to produce it and the Wu Zhu's of the Sui dynasty were produced with an entirely new casting technology.^[23]

Among the varieties of the Sui dynasty era Wu Zhu is one which is particularly well-made composed of what the Chinese call "white copper" (白銅, bái tóng) and are therefore known as "Bai Qian Wu Zhu" (白錢五銖, bái qián wǔ zhū) cash coins and are believed to have been manufactured in the Jiangnan region. The Chinese character "Wu" (五) on these coins is slightly more curved where the lines cross. Wu Zhu cash coins from the Sui dynasty are known to be produced in both larger and smaller sizes, the smaller and lighter Wu Zhu's were produced later as the country was facing higher expenditures and debased the coinage, the last Wu Zhu cash coins of the Sui dynasty circulated alongside improvised currency such as scraps of iron, paper, and leather.^[8]

List of types of Wu Zhu coins

Almost nine hundred different types and over eighteen hundred varieties of Wu Zhu cash coins and Wu Zhu derivatives are known to exist.

List of variants of Wu Zhu cash coins:^[24][8]

Variants of Wu Zhu (五銖) cash coins
Variant	Image
Jun Guo Wu Zhu (Chinese: 郡國五銖; pinyin: jùn guó wǔ zhū) (118–115 BC) is a large and heavy coin, with the edges not filed. Sometimes has a rimless reverse. Taken to be the earliest Wu Zhu. According to the History of Han, in 118 BC the Commanderies (Jun) and Principalities (Guo) were ordered to cast 5 zhu coins with a circular rim so that it would be impossible to clip them to glean a bit of copper.
Chi Ze Wu Zhu (Chinese: 赤仄五銖; pinyin: chì zè wǔ zhū) (115–113 BC) is a lighter coin than the above, with filed edges. The Han records state that in 115 BC the mints in the capital were requested to cast Chi Ze coins, with one being worth five local coins. Only these were to circulate. Chi Ze means Red (or Shining) Edge, referring to the red copper showing when the edges were filed smooth. Some examples of this coin were found from the tomb of Liu Sheng, Prince of Zhongshan, who died in 113 BC.
Shang Lin San Guan Wu Zhu (Chinese: 上林三官五銖; pinyin: shàng lín sān guān wǔ zhū) (From 113 BC) refers to the Three Offices of Shang Lin Park which were the Office for Coinage, the Office for Sorting Copper, and the Office of Price Equalisation. Minting was now confined to the central authorities. These coins usually have a raised rim on the top of the hole on the obverse. Their quality was so high that forgery became unprofitable except to true artisans, great villains, or thieves. All earlier coins were to be melted down and the copper taken to Shang Lin.
Wu Zhu Coins (AD 25). Even after the end of the Wang Mang regime (see below), the coinage system remained in disarray. Cloth, silk and grain were used as money along with coins. However, cash was the normal measure of wealth and was used in large quantities. When Yang Ping (92–195) was in economic difficulties, he was offered a gift of one million cash. Wu Zhu coins continued to be issued, along with other coins, until the end of the sixth century. Some coins can be attributed to specific reigns or events; many can not.
The Iron Wu Zhu, resembling the W. Han coin, is attributed to Gongsun Shu, who rebelled in Sichuan in AD 25, and issued iron coins, two being equal to one Jian Wu Wu Zhu (Chinese: 建武五銖; pinyin: jiàn wǔ wǔ zhū). Head of the zhu component rounded. Typical of Eastern Han Wu Zhu's. In AD 30, a ditty was sung by the youths of Sichuan: "The yellow bull! the white belly! Let Wu Zhu coins return". This ridiculed the tokens of Wang Mang and the iron coins of Gongsun Shu, which were withdrawn by the Eastern Han Emperor Guangwu in the 16th year of Jian Wu (AD 40). The Emperor was advised that the foundation of the wealth of a country depends on a good political economy, which was found in the good old Wu Zhu coinage, and so reissued the Wu Zhu coins.
The Si Chu Wu Zhu (Chinese: 四出五銖; pinyin: sì chū wǔ zhū; lit. 'Four Corner five zhu') has four lines on reverse radiating from the corners of the hole. It is attributed to the Eastern Han Emperor Ling, AD 186. The four lines are said to represent wealth flowing from a ruined city—an omen of the overthrow of the Han Dynasty.
There is a type of Wu Zhu cash coins which displays a long, prominent horizontal line on the obverse right above the square center hole. The diameter of this particular type of Wu Zhu cash coins tend to be around 20.6 millimeters and their weight generally is around 1.7 grams.
There is a type of Wu Zhu cash coins which is distinctive in that it has three slanted lines above, and three slanted lines below, the square center hole. The slanting lines are raised above the surface which means that they had to be a part of the coin mould at the time of their production. The three lines above and the three lines below resemble the symbols on the Western Han dynasty era Ban Liang cash coins. This type of Wu Zhu cash coins generally tends to have a diameter of 23 millimeters and their weight tends to be around 1.8 grams.
There are several types of Eastern Han dynasty era Wu Zhu cash coins which have four lines (or possibly elongated dots) to the left of the square center hole on the reverse side of the cash coin. These ancient Chinese symbols are similar to those that appeared on the reverse sides of some Western Han dynasty era Ban Liang cash coins. These types of Wu Zhu cash coins generally tend to have a diameter of 22.6 millimeters and a weight of 1.4 grams.
There is a type of Wu Zhu cash coins that has four (4- oblique lines extending outward from each corner of the square center hole to the rim on the reverse side of the cash coin. In Mandarin Chinese, this technique is referred to as "Si Chu" (四出), "Si" (四) translates as "four" and "Chu" (出) translates as "going out". This type of cash coin is also known as a "corner coin" (角钱), and these "corner coins" are generally believed to have been manufactured in the year 186 AD during the reign of Emperor Ling of the Eastern Han dynasty. As cities in ancient China had walls built around them as a means of protection against outside attacks. It is often said that the square center hole of this coin represented the city and that the four lines going out represented wealth flowing out, portending the fall of the Eastern Han dynasty in the year 220 AD. The diameter of this series of Wu Zhu cash coins tends to be around 25 millimeters and their weight tends to generally be around 3.1 grams.
There is another type of "Si Chu" (四出) Wu Zhu cash coins or "corner" Wu Zhu cash coins with four lines radiating outward from the square center hole, this variant is made from iron. This specific type was made in the year 523 AD during the reign of Emperor Wu of the Liang dynasty (a country which existed from the year 502 AD until the year 557 AD). This type of Wu Zhu cash coins generally tend to have a diameter of 20.5 millimeters and a general weight of 2.6 grams.
Some types of Wu Zhu cash coins contain Chinese characters and/or other ancient Chinese symbols. There is type of Eastern Han dynasty era Wu Zhu cash coins with the Hanzi (Chinese) character "Xiao" (小), which could be translated as "small", just above the square center hole, such characters as these may have indicated the area or limits in which these coins were intended to circulate to prevent them from circulating outside. This type of Wu Zhu cash coins generally tend to have a diameter of 24.3 mm and their average weight is around 2.1 grams.
There is a type of Wu Zhu cash coins produced during the Eastern Han dynasty era that has the Chinese character "Wang" (王) on the reverse side of the cash coin, rotated ninety (90) degrees, below the square center hole. "Wang" could be translated as "king" but it is also a common family name in China. In this instance the "Wang" Chinese character rises above the field of the cash coin which indicates that it was a designed into the coin mould. This type of Wu Zhu cash coins generally tend to have a diameter of 22.7 millimeters and an average weight of 2 grams.
There is a type of Wu Zhu cash coins which have the Chinese character "Gong" (工) meaning "work" or "industry" written below the square center hole on the obverse side of the cash coin. The "Gong" character is "in relief" (阳文) meaning it was engraved into the coin mould in the same way as the other Chinese characters used in its legend or inscription. This type of Wu Zhu cash coins generally tend to have a diameter which is around 23.7 millimeters and their weight tends to be around 2.3 grams.
There is another type of Wu Zhu cash coins which also display a very distinct "Gong" (工) Chinese character meaning "work" or "industry", however this type tends to have the "Gong"on the reverse side of the cash coin below the lower left corner of the square center hole. The diameter of this type of Wu Zhu cash coins generally is around 26 millimeters and their weight is generally around 2.8 grams.
There is a type of Wu Zhu cash coins which display ancient Chinese auspicious symbols, both above and below the square hole are swastikas. In China the swastika represents the Hanzi (Chinese) character "Wan" (万) which could be translated "ten-thousand". The extended meaning of "Wan" would be "all" such as "the myriad things" as it was used to represent in classic Taoist text written by Laozi the Tao Te Ching (道德經).This type of Wu Zhu cash coins have diameters which is generally around 23.5 millimeters and their weight tends to generally be around 2.3 grams.
Shu Wu Zhu (Chinese: 蜀五銖; pinyin: shǔ wǔ zhū) coins have the word Chuan (Chinese: 川; pinyin: chuān) on the obverse, or the numbers 1–32 on the reverse, in incuse characters. They are attributed to the Shu Han (221–265) by virtue of their find spots in Gansu.
Shen Lang Wu Zhu (Chinese: 沈郎五銖; pinyin: shén láng wǔ zhū; lit. 'Lord Shen's') has no jin component in zhu. They are attributed to Shen Chong of the House of Wu and cast after the foundation of the Eastern Jin Dynasty in 317. Also known as the Shen Chong Wu Zhu (Chinese: 沈充五銖; pinyin: shén chōng wǔ zhū); an old ballad contains the lines: "Elm seeds countless press in sheets, Lord Shen's green cash line town streets." Apparently this means that Lord Shen's cash were small and light.
Dang Liang Wu Zhu (Chinese: 當兩; pinyin: dāng liǎng; lit. 'Worth Two') is a large thick coin, with a nominal weight of 8 zhu. They are attributed to Emperor Wen of the Southern Dynasties Song Dynasty, who had them cast in 447 as a measure against coining malpractices.
There is a type of Wu Zhu cash coins with the character for "ten" (十) incused above the square center hole on the obverse side of the cash coin. The "ten" on these cash coins was engraved sometime after it was manufactured. The diameter of this type of Wu Zhu cash coins is generally around 25.9 millimeters and their weight tends to be around 2.8 grams.
There is a type of Wu Zhu cash coins where the Hanzi (Chinese) character "ten" (十) on the reverse side of the cash coin protrudes above the surface of the cash coin and is located above the square center hole. This series of Wu Zhu cash coins generally have a diameter of 22 millimeters and tend to have a weight of 1.4 grams.
There is a series of Wu Zhu cash coins which has the Hanzi (Chinese) character for "ten" (十) on its reversed side where is incused above the square hole. This type of Wu Zhu cash coins generally have a diameter of 24.5 millimeters and a weight of 2 grams.
There are various types of Wu Zhu cash coins that incorporate counting rods which are also known as "rod numbers" (numerals), this ancient form of writing Chinese numbers that occasionally appear on old Chinese cash coins rod numerals are believed to have been mainly used for doing calculations.. Among the types of Wu Zhu cash coins with rod numerals is one specific type produced under the reign of the Eastern Han Dynasty. The distinctive feature of these cash coin is that there are four vertical bars (or lines) incused below the square center hole. "Incuse" means that the lines were cut, engraved or punched into the Wu Zhu cash coin, it is currently still unclear why they sometimes appear on these very old Chinese coins. As seen in the Wu Zhu cash coins that display the Chinese numbers "one" (一), "two" (二) and "three" (三) consist of one, two and three lines, respectively, one might guess through deduction that the number "four" would consist of four lines which is not the case with modern Chinese but it was the case in the ancient rod numeral system. For this reason it odd believed that the four lines on this type of Wu Zhu cash coins probably represent the number "four" in ancient Chinese rod numerals. The coins with one, two and three lines in actually may also be rod numerals since they are written empirically the same as the characters in modern Chinese. This type of Wu Zhu cash coins generally has a diameter of 24.5 millimeters and a weight of 2.1 gram.
There is a type of Wu Zhu cash coin which above the hole of has a short vertical line intersected by a longer horizontal line. This ancient Chinese symbol, which resembles a "T" turned on its side, appears to be the rod number "six" as written in the old Chinese rod numeral system. This series of Wu Zhu cash coins generally have a diameter of 22.6 millimeters and tend to have a weight of 1.9 grams.
There is a type of Wu Zhu cash coins on which there appears to be the ancient Chinese rod numeral "six" below the square center hole the reverse side of the cash coin. The diameter of this series of Wu Zhu cash coins is generally around 23 millimeters and their weight averages out around 1.7 grams.
There is a type of Wu Zhu cash coins which above the square center hole appear to have an ancient Chinese rod numeral, this ancient Chinese rod number appears to be protruding above the surface of the cash coin, it is a horizontal line with three vertical lines underneath. This is the ancient Chinese rod numeral symbol for "8" (eight). The series of Wu Zhu cash coins is also unusual because of the two dots (which are meant to represent "stars" on ancient Chinese cash coins) inside the "Wu" (五) Chinese character to the right of the square center hole. There is one dot (or "star") in the upper half and one dot (or "star") in the lower half of the character. This symbol gives the appearance of two eyes staring at the observer. Which is why this Eastern Han dynasty era Wu Zhu cash coin variety with the "two eyes" is known as "Chang Ming Wu Zhu" (長明五铢). This type of Wu Zhu cash coins generally has a diameter of 21 millimeters and a weight of 1.4 grams.
There is a series of Wu Zhu cash coins which has an ancient Chinese symbol above the square center hole which is very similar to a rod numeral. This symbol resembles the Chinese character "Shang" (上), which means "up", except that the upper horizontal stroke is on the left instead of the right. Gary Ashkenazy speculates that it is an alternative way of writing "six" in ancient Chinese rod numerals or that it might stand for "seven". Gary Ashkenazy also proposes that it might not be a number at all. This type of Wu Zhu cash coins generally tend to have a diameter of 23 millimeters and tend to have a weight of 1.7 grams.
Some types of Wu Zhu cash coins have what appear to be lines, among them is a very specific type which on its obverse side has a very prominent vertical line (竖) above, and another very prominent vertical line below the square center hole. This series of Wu Zhu cash coins tend to have a diameter of 22.5 millimeters and a weight of 1.8 grams.
There is a type of Eastern Han dynasty era Wu Zhu cash coins which have a long vertical line above and another below the square center hole on the reverse side. Since in this specific type of Wu Zhu cash coins the lines tend to be raised above the coin's surface, these lines had to have been intentionally included in the casting mould from which the cash coin was manufactured. The diameter of this type of Wu Zhu cash coins tend to be 23 millimeters and their weight is generally around 2 grams.
Tian Jian Wu Zhu has an inner rim on obverse. At the start of the Liang Dynasty, money was only used around the capital. Elsewhere grain and cloth were used for trade. In the south, everyone used gold and silver. Therefore, in the 1st year of the Tian Jian period (502), the Emperor Wu cast Wu Zhu coins with an outer and inner rim. He also cast another sort without a rim called the female coin. The two sorts circulated together.
Nu Qian (Chinese: 女錢; pinyin: nǚ qián; lit. 'The Female Coin') have no outer rim.
An iron Wu Zhu with four lines radiating from the corners of the hole on the reverse. Attributed to Emperor Wu of Liang in 523. By 535, the traders in Sichuan were complaining of the trouble of stringing together such a number of [cheap] coins, and of the large number of carts needed to transport them.
There is a type of Wu Zhu cash coins which has two vertical lines in relief above the square center hole on the reverse side of the cash coin. The two lines allegedly represent the number "two" in Chinese (二). These Wu Zhu cash coins tend to have a diameter of 23 millimeters and a weight of 1.7 grams.
There is a type of Han dynasty era Wu Zhu that has three vertical lines above the square center hole. These three lines allegedly represent the Chinese number "three" (三). These Wu Zhu cash coins tend to have a diameter that is 25.3 millimeters and their weight tends to be around 2.8 grams.
There is a type of Wu Zhu cash coins that are similar to the type described above except that there are three slanting lines located below the square center hole. The three lines allegedly also represent the Chinese character for "three" (三). These Wu Zhu cash coins tend to have a diameter that is 22.5 millimeters and their weight tends to be around 1.6 grams.
There is a type of Wu Zhu cash coins (五銖錢) that has a second "Wu" (五) Chinese character meaning "five" above the square center hole. This second "Wu" Chinese character is raised above the surface of the Wu Zhu cash coin the same as the Hanzi characters to the right and left of the hole. This means the second "Wu" Chinese character was actually intentionally engraved into the mould in the same manner as the other Chinese characters. This type of Wu Zhu cash coins tends to have a diameter of 23 millimeters and a weight of 2.2 grams.
There is a type of Wu Zhu cash coin has another "Wu" (五) Chinese character, meaning "five", located to the left of the square center hole on the reverse side of the Wu Zhu cash coin. Unlike the type mentioned above, this "Wu" character is actually incused. This type of Wu Zhu cash coins has a diameter of 24 millimeters and a weight of 1.8 grams.
There is a type of Wu Zhu cash coins that have the Hanzi character "Liu" (六), which means "six", incused at the right of the square center hole and is rotated ninety (90) degrees in the clockwise direction. The incused character was engraved into the coin after it had already been manufactured and was not a feature of the mould itself from which the Wu Zhu cash coin was produced. The diameter of these types of Wu Zhu cash coins 23.5 millimeters and their weight is usually 1.6 grams.
There is a type of Wu Zhu cash coins that has the Hanzi (Chinese) character "Ba" (八), which means "eight" on the reverse side of the cash coin, incused above the square center hole. The "Ba" in this is usually upside down. This type of Wu Zhu cash coins generally have a diameter of 22.2 millimeters and a weight of 1.7 grams.
There is a type of Wu Zhu cash coins that has the number "nine" (九) incused (or carved) right above the square center hole. There is usually also an incused line running vertically through the "Wu" (五) Chinese character on the right side of this type of Wu Zhu's. The diameter of this type of Wu Zhu cash coins is 26.2 millimeters and their weight generally is at 3 grams.
There is a type of Eastern Han dynasty era Wu Zhu cash coins that has a rather large and unusually well made Hanzi (Chinese) character "ten" (十) below the square center hole. The diameter of this type of Wu Zhu cash coins is generally around 23 millimeters and their weight tends to be around 2.6 grams.
There is a rather unusual type of Wu Zhu cash coins which have the Hanzi (Chinese) character for "ten" (十) above the square center hole. Below the square center hole are two dots (which represent two "stars"). The dots (or "stars") and the "ten" Chinese character are in relief which means that they protrude above the coin surface and were part of the original design of the mould from which the Wu Zhu cash coins were cast. This type of Wu Zhu cash coins tend to have a diameter of 24.5 millimeters and a weight which is generally around 2.9 grams.
Liang Zhu Wu Zhu (Chinese: 兩柱五銖; pinyin: liǎng zhù wǔ zhū; lit. 'Two Pillar') has a dot above and below the hole on the obverse. They are attributed to Emperor Yuan of the Liang Dynasty in 552. They were intended to be the equivalent of ten ordinary coins.
Si Zhu Wu Zhu (Chinese: 四柱五銖; pinyin: sìzhù wǔ zhū; lit. 'Four Pillar') have two dots on the obverse and reverse. They are attributed to Emperor Jing of the Liang Dynasty in 557. They were originally intended to be the equivalent of twenty ordinary coins, they soon became worth one. However, similar coins with dots have been found in tombs of a much earlier date.
Chen Wu Zhu. (Chinese: 陳五銖; pinyin: chén wǔ zhū) has a stout outer rim and no inner rim. The top part of the zhu component is square while the bottom part round. They are attributed to Emperor Wen of the Southern Dynasties Chen Dynasty and cast from Tian Jia 3 (562). One Chen Wu Zhu was worth ten small goose-eye coins.
There is a type of Eastern Han dynasty era Wu Zhu cash coins that has a short bar or Chinese (Hanzi) character "one" (一) situated above the character "Wu" (五) at the right of the square center hole. This type of Wu Zhu cash coins has a diameter of 25.9 millimeters and a weight of 2.8 grams.
There is a type of Wu Zhu cash coins where the "one" (一) is located below the Chinese character "Wu" (五) to the right side of the square center hole. These Wu Zhu cash coins have a diameter of 23.3 millimeters and a weight of 1.8 grams.
There is a type of Wu Zhu cash coins that has on its obverse side (far left) a prominent "one" (一) located below the character "Wu" (五). However, the most distinctive feature or characteristic of this Wu Zhu cash coin is the center hole which is not square in shape unlike the far majority of other Chinese cash coins. Most non-square center holes are actually the result of insufficient molten bronze flowing to certain parts of the coin mould. The borders of the holes, in these cases, tend to be very ragged, irregular, and even uneven. This Han Dynasty era Wu Zhu cash coin is actually fairly well-made and has a "number" symbol meaning it received special attention during its casting process. The coin's unusual hole, while not square, is still too regular to have been formed by any form of accident. There are documented reports of similar Wu Zhu cash coins having been found with unusual center holes which appear to probably have been intentionally made. According to Gary Ashkenazy there is an article in the 1987 (seventh issue) of the Chinese periodical "Shaanxi Finance" (陝西金融, shǎn xī jīn róng) which shows rubbings of several wu zhu coins with unusual holes found in a hoard. One Wu Zhu cash coin is indeed very similar to this specific type but has only one, in contrast to two, square-like projections extending beyond the normal border of the center hole. The article also showed illustrations of several cash coins which had triangular-shaped projections extending beyond the border of the inner hole. According to Gary Ashkenazy the author of the article says that the coins did not show any indication that the holes were modified by force in any manner at some time after their casting. The author of the article was unable to propose what these distinctive holes may mean or symbolise as these things remain unknown. These Wu Zhu coins, with their modified square holes, may very well have been the precursor of the Chinese cash coins with "flower" or "rosette" holes (花穿錢) which were to become fairly common by the time of the Song Dynasty (960-1279). This type of Wu Zhu cash coins has a diameter of 26.2 millimeters and a weight of 2.5 grams.
There is a type of Wu Zhu cash coins that also has the Chinese character (一) meaning "one". But unlike the earlier types the "one" is above the "Zhu" (銖) Chinese character at the left of the side of the Square center hole. These Wu Zhu cash coins tend to have a diameter of 26.2 millimeters and a weight of 2.4 grams.
There is a type of Wu Zhu cash coins where the character "one" (一) is below the "Zhu" (銖) character at the left side of the square center hole. The diameter of this particular type of Wu Zhu cash coins tend to be around 25.8 millimeters and their weight tends to be around 2.7 grams.
There is a particular type of Wu Zhu cash coins which has two long horizontal lines above the square center hole which may or may not represent the Chinese character (Hanzi) for "two" (二). The diameter of these Wu Zhu cash coins is 23.9 millimeters and their weight is 2.1 grams.
There is a type of Wu Zhu cash coins which has two short horizontal lines above the "Zhu" (銖) character at the left of the square center hole. These two parallel lines represent the Chinese character (Hanzi) for "two" (二). These Wu Zhu cash coins have a diameter of 23.3 millimeters and a weight of 1.8 grams.
There is a type of Wu Zu cash coins that was cast during the "Six Dynasties period" in Chinese history, during this time some very refined cash coins were cast, however most cash coins from this period can be described as rather crude and inferior. Among these types of cash coin is an Wu Zhu can coin where the "Zhu" (銖) character to the left of the square center hole has been simplified so that only its right side component of "Zhu" (朱) appears. What is further unusual about this type of Wu Zhu cash coins is that there are two vertical bars incused just above the hole which according to Gary Ashkenazy probably represent the Chinese character for "two" (二). This type of Wu Zhu cash coins have a diameter of 22.3 millimeters and a weight of 2.5 grams.
There is a Han dynasty era Wu Zhu cash coins that have a short vertical line or bar above the square center hole. This symbol may or may not represent the Chinese number "one" (一) as the purpose of these marks has yet to be revealed by modern archeologists. This series of Wu Zhu cash coins tend to have a diameter is 25.65 millimeters and a weight of 2.6 grams.
There is a type of Han dynasty era Wu Zhu cash coins that on their obverse side have two vertical lines in relief (known as "阳文" in Mandarin Chinese) above the square center hole. The two lines represent the Chinese number "two" (二) . The diameter of this type of Wu Zhu cash coins is 23.4 millimeters and their weight is 2.1 grams.

There is a type of Wu Zhu cash coins which to the left has four large slanting dots (which all represent "stars") on its obverse side above the square hole. These Wu Zhu cash coins have a diameter of 24.2 millimeters and a weight of 2 grams.
There is a type of Wu Zhu cash coins which were all probably cast during the reign of the Eastern Han dynasty, that appear to have what seems to be a series of four "stars" (or "dots") on its reverse side below the square hole. And to the left of these dots (which represent "stars") is a small crescent (which may or may not represent the "moon"), as is what seems to generally be the case with some the very oldest coins with charm-like symbols, the exact meaning and their intent currently remain unclear. These Wu Zhu cash coins have a diameter of 24.5 millimeters and a weight of 2.8 grams.
Another type of Eastern Han dynasty era Wu Zhu cash coins has five dots (representing "stars") above the square hole. These Wu Zhu cash coins have a diameter of 24 millimeters and a weight of 2.8 grams.
Another type not too dissimilar as the Eastern Han dynasty wra Wu Zhu cash coins also have five dots (representing "stars") above the square center hole but these in a different configuration. The diameter of these Wu Zhu cash coins is 25 millimeters and their weight is 2.1 grams.
Another type of Eastern Han dynasty era Wu Zhu cash coins have a series of five dots (representing "stars") below the square center hole on its obverse side. The coin's diameter in this type of Wu Zhu cash coins is 23.7 millimeters and their weight is 2.4 grams.
Soke Wu Zhu cash coins with Circles (representing the "Sun") tend to be rather nicely cast, these Wu Zhu cash coins have a "circle" (representing the "sun") below the square center hole. These Wu Zhu cash coins have a diameter of 25.2 millimeters and a weight of 4.1 grams.
Some types of Wu Zhu cash coins contain numbers. Among them is yet another type of Eastern Han dynasty era Wu Zhu cash coins. This particular type has one horizontal line, which represents the Hanzi character for "one" (一), below the square center hole. This short line which represents the number "one" was neither cut or engraved into the Wu Zhu cash coin. Instead, the symbol was already designed into the mould and even protrudes above the surface of the coin the same as the Hanzi characters "Wu Zhu" (五銖). These Wu Zhu cash coins have a diameter of 26.4 millimeters and a weight of 3.1 grams.
Sui Wu Zhu (Chinese: 随五銖; pinyin: suí wǔ zhū) is hourglass wu, inner rim by the wu only. They were first cast by Emperor Wen in 581. After introducing these new coins, the Emperor ordered all the frontiers to hand over 100 cash as samples in 583, and the next year strictly forbade the circulation of old coins and commanded that when this was disobeyed, the responsible officials should be fined half a years salary. 1,000 coins weighed 4 jin 2 liang. Minting privileges were granted to several imperial princes during this reign.
Bai Qian Wu Zhu (Chinese: 白錢五銖; pinyin: bái qián wǔ zhū; lit. 'White Coin') has writing as above. The whitish colour of this coin is due to the addition of lead and tin to the alloy, which was done officially from 585.
Yan Huan Wu Zhu (Chinese: 綖環五銖; pinyin: yán huán wǔ zhū; lit. 'Fringe or Thread Ring') is a Wu Zhu whose middle has been cut out to make two coins.
Some Wu Zhu cash coins have reversed inscriptions similar to the Ban Liang cash coins, these Wu Zhu can coins were cast with the inscription (legend) reversed. Usually, the "Wu" (五) is on the right side of the cash coin while the "Zhu" (銖) is on the left.On these "reverse inscription" Wu Zhu coins, however, the "Wu" (五) is on the left side of the cash coin while the "Zhu" (銖) is on the right. The Mandarin Chinese term for this reversal of Chinese characters is chuán xíng (傳形). Currently, the meaning or significance of reversing the two Chinese characters on these early cash coins is still unknown.
Wu Zhu Coins with Dots or "Stars", Some of these have a very well formed dot or "star" above the upper left corner of the square hole. The "star" (dot) in this variant actually has a small tail which makes it appear similar to a shooting star or a "tadpole lucky cloud". These cash coins generally have a diameter of 25.7 millimeters and a weight of 3.2 grams.

There is an Wu Zhu cash coin that has a very large dot (or "star" in Chinese symbolism) just below the square hole, these cash coins notably have no outer rim. For this reason, these cash coin are known as the "Gongshi Nüqian" (公式女銖) and were cast during the Southern dynasties period (which latsted from 420 AD until 589 AD) and were produced in the year 502 AD by Emperor Wu of the Liang dynasty (a country which existed from the year 502 AD until 557 AD). These cash coins have a diameter of 22.5 millimeters and a weight of 1.4 grams.
During the Eastern Han dynasty (which lasted from 25 AD until 220 AD) an Wu Zhu cash coin with a "star" (represented by a dot) below the square center hole was cast. In certain specimens, however, the dot is not round but triangular in shape. These particular versions of the Wu Zhu cash coin have a diameter of 25.8 millimeters and a weight of 2.7 grams.
There is an Wu Zhu cash coin which on the reverse side has a single "star" (or "dot") located to the left of the square center hole and near the rim of the cash coin. These cash coins have a diameter of 26 millimeters and a weight of 3.1 grams.
There is an Wu Zhu cash coin that has a large triangular dot (or "triangular star") just above the square center hole.

Zao Bian Wu Zhu (Chinese: 鑿邊五銖; pinyin: záo biān wǔ zhū; lit. 'Chiselled Rim') is the inner portion of a Wu Zhu whose outer portion has gone to make a thread ring. Surviving moulds show that some Wu Zhu's were actually cast like this.
E Yan (Chinese: 鵝眼; pinyin: É yǎn; lit. 'Goose Eye') or Ji Mu (Chinese: 雞目; pinyin: jī mù; lit. 'Chicken Eye') are the names given to various diminutive Wu Zhu coins. This is a common type with sharp legends which has been found in Western Han tombs of 73–33 BC.
Small coins with no characters. Traditionally ascribed to Dong Zhuo (Chinese: 董卓; pinyin: dǒngzhuō), who in 190 usurped the throne and melted down nine huge Qin Dynasty statues to make coins. Could well have been cast at other times.^[25]

Kingdom of Kucha

Main article: Kucha coinage

 

A "Han Gui bilingual Wu Zhu coin" (漢龜二體五銖錢) produced by the Kingdom of Kucha with both a Chinese and a Kuśiññe inscription.

The Kingdom of Kucha was a Buddhist state located in present-day Kucha County, Xinjiang, it was first recorded during the Han dynasty and was later annexed by the Tang, during its time it was a prominent player on the silk road. From around the third or fourth century the Kingdom of Kucha began the manufacture of Wu Zhu cash coins inspired by the diminutive and devalued Wu Zhu's of the post-Han dynasty era in Chinese history.^[26]

There are five known types of Kucha cash coins based on the Chinese Wu Zhu's which are usually characterised by the fact that they're diminutive in size, very thin, and tend to have both weak and irregular inscriptions while four of these types tend to have no inscriptions at all. One type of Kucha Wu Zhu cash coin is the "Han Gui bilingual Wu Zhu coin" (漢龜二體五銖錢, hàn guī èr tǐ wǔ zhū qián) which are characterised by the fact that the obverse side resembles Chinese Wu Zhu coins while the reverse sides feature a local Kucha script above and below the square center hole.^[27][28] As the language of the Kingdom of Kucha isn't well preserved in the modern era many hypotheses have been suggested about its meaning including that it is simply a translation of "Wu Zhu" or feature the name of the Kingdom of Kucha in the Kuśiññe language.^[29] Cash coins without any inscription cast in this region are generally believed to have been produced between the years 265 and 589, the first variant of these cash coins are round in shape and have a rim around the square centre hole on one side while the other side is rimless, they tend to thin on the outside while they're thick on the inside and weigh between 0.4 grams 1.7 grams, and have a diameter of 9 to 18 millimetres. The second type can be described as similar to the aforementioned type but have no inner rim, these cash coins generally from 8 to 13 millimetres in diameter and have a weight of 0.2 to 0.4 grams. The third type of these cash coins are also completely without rim but are square in shape and have a square centre hole, they tend to be very thin with diameters between 8 and 11 millimetres and weigh between 0.2 and 0.5 grams. The final variant are irregularly shaped, diminutive in size, thin, and are cast of poor workmanship. Some are merely five millimetres in diameter and weigh as little as 0.2 grams.

The Buddhist monk Xuanzang describes that there are "small bronze coins" in the city of Kucha while he visited there in the year 630 which is mentioned in his work "Great Tang Records on the Western Regions" during the Tang dynasty. These cash coins are likely to have been the "Han Gui bilingual Wu Zhu coin".^[8]

Wu Zhu coins and the emergence of Chinese charms

Main article: Chinese numismatic charm

Wu Zhu cash coins played a central role in the emergence of Chinese numismatic charms,^[30][31] as the Wu Zhu cash coins were cast in enormous quantities during both the Western Han dynasty and the subsequent seven hundred years of its usage not all variants can be directly attributed to every ruler, however "auspicious" symbols such as stars (dots), suns (circles), moons (crescents), numbers, rod numerals, Hanzi characters, lines, and others started to be used after the Eastern Han dynasty, the reason for the earlier uniformity was the usage of bronze moulds which last for a long time, these moulds continued to be used over and over again by subsequent dynasties. However, as other techniques such as mother coins started to be used some mints started adding these "auspicious" symbols which became the inspiration for later Chinese charms and amulets.^[32][33][34] Although the usage of some these symbols were already used on the earlier Ban Liang cash coins, they became more common on the Wu Zhu. It unclear why exactly these symbols started being added in large quantities during the Eastern Han dynasty and later but the first Chinese charms and amulets started emulating their design. Some of these early Wu Zhu coins also had the precursors to the "flower" or "rosette" holes found on later cash coins as such coins were discussed in an article in the 1987 (7th issue) of the Chinese periodical "Shaanxi Finance" (陝西金融, shǎn xī jīn róng) which shows rubbings of several Wu Zhu cash coins with unusual center holes found in a hoard.^[35][36][37]

Wu Zhu charms

A later reproduction of a Wu Zhu cash coin to serve as a Chinese "good luck" charm or "lucky coin".

Chinese numismatic charms based on Wu Zhu cash coins tend to feature the same "auspicious symbolism" as contemporary Wu Zhu cash coins had themselves including crescents representing the moon, circles representing the sun,^[38] and dots representing the stars, in fact to an untrained eye Wu Zhu charms can be interchangeable with regular Wu Zhu coins. Other than these features it's also not uncommon for Wu Zhu charms to feature wholly original iconography from various aspects of Chinese culture such as a dragon and a fisherman.^[39] Other than simply having the inscription "Wu Zhu" some Wu Zhu charms are also based on other variants of the Wu Zhu cash coins with four character inscriptions that incorporate the legend "Wu Zhu".^[40][41]

Hoards of Wu Zhu cash coins

See also: List of coin hoards in China

In the modern era hoards of Wu Zhu cash coins tend to be very common in China as these coins were produced in large quantities.

• In 2000 at the archeological site of So Kwun Wat, Tuen Mun in the special administrative region of Hong Kong over sixty Han dynasty era bronze cash coins were unearthed which included both Ban Liang (半兩) and Wu Zhu (五銖) cash coins, among the hoard were also pieces of linen and bamboo mats.^[42]
• In January 2006 during the construction of a plaza in Pingli County, Shaanxi a Han dynasty era tomb was uncovered, during its excavation archeologists found 259 Wu Zhu cash coins, 1 tripod made from iron, a pottery kitchen range as well as 3 pottery urns.^[43]
• On 16 July 2012 a large cache of 14,000 ancient Chinese coins was found in Kuqa, Xinjiang which included Han dynasty era Wu Zhu (五銖) and "Chiseled rim Wu Zhu" (鑿邊五銖) cash coins, Xin dynasty era Huo Quan (貨泉) and Daquan Wushi (大泉五十) cash coins, a Three Kingdoms period Taiping Baiqian (太平百錢) cash coins, as well as native cash coins. Alongside the cash coins were shards of pottery as well as fragments of human bones which lead the archeologists believe that this was an old cemetery.^[44]
• In August 2012 a large hoard of Wu Zhu cash coins and Xin dynasty era cash coins was found in the city of Huoluochaideng, Inner Mongolia. The hoard included 3500 kg of Chinese cash coins and around 150 clay moulds used to manufacture coins from the Xin dynasty. According to archeologists the site might've been a mint that was in operation since the reign of Emperor Wu until Emperor Wang Mang.^[45][46][47]
• In 2015 Chinese archeologists uncovered 10 tonnes of bronze Wu Zhu cash coins from the Western Han dynasty (or around 2 million coins) alongside over ten thousand of other iron, bronze, and gold items in the Haihunhou cemetery near Nanchang, Jiangxi, among the other uncovered items were bamboo slips, wood tablets, as well as jade objects. As these Wu Zhu cash coins were strung in strings of 1000 pieces this proved that the practice of stringing cash coins per 1000 didn't first happen during the Tang dynasty as was previously thought but actually six hundred years earlier.^[48][49]
• In 2018 in South Korea 26 Wu Zhu cash coins were unearthed in a tomb in Kyongsan, North Gyeongsang.^{[citation needed]}
