Cash (Chinese coin)
Cash was a type of coin of China and East Asia, used from the 4th century BC until the 20th century AD, characterised by their round outer shape and a square center hole (方穿, fāng chuān). Originally cast during the Warring States period, these coins continued to be used for the entirety of Imperial China as well as under Mongol, and Manchu rule. The last Chinese cash coins were cast in the first year of the Republic of China. Generally most cash coins were made from copper or bronze alloys, with iron, lead, and zinc coins occasionally used less often throughout Chinese history. Rare silver and gold cash coins were also produced. During most of their production, cash coins were cast, but during the late Qing dynasty, machine-struck cash coins began to be made. As the cash coins produced over Chinese history were similar, thousand year old cash coins produced during the Northern Song dynasty continued to circulate as valid currency well into the early twentieth century.
Replicas of various ancient to 19th century cast cash coins in various metals found in China, Korea and Japan.

In the modern era, these coins are considered to be Chinese “good luck coins”; they are hung on strings and round the necks of children, or over the beds of sick people. They hold a place in various superstitions, as well as Traditional Chinese medicine, and Feng shui. Currencies based on the Chinese cash coins include the Japanese mon, Korean mun, Ryukyuan mon, and Vietnamese văn.

The English term cash, referring to the coin, comes from the Portuguese caixa which was derived from the Tamil kāsu, a South Indian monetary unit derived from the Sanskrit silver and gold weight unit karsa. The English word cash meaning "tangible currency" is an older, unrelated word, derived from the Middle French caisse.
There are a variety of Chinese terms for cash coins, usually descriptive and most commonly including the character qián (Chinese: 錢; pinyin: qián) meaning "money". Chinese qián is also a weight-derived currency denomination in China; it is called mace in English.
Traditionally, Chinese cash coins were cast in copper, brass or iron. In the mid-19th century, the coins were made of 3 parts copper and 2 parts lead.[where?][page needed] Cast silver coins were periodically produced but considerably more rare. Cast gold coins are also known to exist but are extremely rare.
Early methods of castingEdit
During the Zhou dynasty period, the method for casting coins consisted of first carving the individual characters of a coin together with its general outline into a mould made of either soapstone or clay. As this was done without using a prior model, early Chinese coinage tends to look very diverse, even from the same series of coins as these all were cast from different (and unrelated) moulds bearing the same inscriptions.
Later methods of manufactureEdit
From the 6th century AD and later, new "mother coins" (mǔ qián 母錢) were cast as the basis for coin production. These were engraved in generally easily manipulated metals such as tin. Coins were cast in sand moulds. Fine wet sand was placed in rectangles made from pear wood, and small amounts of coal and charcoal dust were added to refine the process, acting as a flux. The mother coins were placed on the sand, and another pear wood frame would be placed upon the mother coin. The molten metal was poured in through a separate entrance formed by placing a rod in the mould. This process would be repeated 15 times and then molten metal would be poured in. After the metal had cooled down, the "coin tree" (qián shù 錢樹) was extracted from the mould (which would be destroyed due to the process). The coins would be taken off the tree and placed on long square rods to have their edges rounded off, often for hundreds of coins simultaneously. After this process, the coins were strung together and brought into circulation.
From 1730 during the Qing dynasty, the mother coins were no longer carved separately but derived from "ancestor coins" (zǔ qián 祖錢). Eventually this resulted in greater uniformity among cast Chinese coinage from that period onwards. A single ancestor coin would be used to produce tens of thousands of mother coins; each of these in turn was used to manufacture tens of thousands of cash coins.
During the late Qing dynasty under the reign of the Guangxu Emperor in the mid 19th century the first machine-struck cash coins were produced, from 1889 a machine operated mint in Guangzhou, Guangdong province opened where the majority of the machine-struck cash would be produced. Machine-made cash coins tend to be made from brass rather than from more pure copper as cast coins often were, and later the copper content of the alloy decreased while cheaper metals like lead and tin were used in larger quantities giving the coins a yellowish tint. Another effect of the contemporary copper shortages was that the Qing government started importing Korean 5 fun coins and overstruck them with "10 cash".
The production of machine-struck cash coins in Qing China ran contemporary with the production of machine-struck French Indochinese Nguyễn cash coins, but unlike in China milled cash coinage would eventually become popular in French Indochina with the Khải Định Thông Bảo (啓定通寶) .
Chinese cash coins originated from the barter of farming tools and agricultural surpluses. Around 1200 BC, smaller token spades, hoes, and knives began to be used to conduct smaller exchanges with the tokens later melted down to produce real farm implements. These tokens came to be used as media of exchange themselves and were known as spade money and knife money.
As standard circular coins were developed following the unification of China by Qin Shi Huang, the most common formation was the round-shaped copper coin with a square or circular hole in the center, the prototypical cash. The early Ban Liang coins were said to have been made in the shape of wheels like how other Ancient Chinese forms of coinage were based on agricultural tools. The hole enabled the coins to be strung together to create higher denominations, as was frequently done due to the coin's low value. The number of coins in a string of cash (simplified Chinese: 一贯钱; traditional Chinese: 一貫錢; pinyin: yīguànqián) varied over time and place but was nominally 1000. A string of 1000 cash was supposed to be equal in value to one tael of pure silver. A string of cash was divided into ten sections of 100 cash each. Local custom allowed the person who put the string together to take a cash or a few from each hundred for his effort (one, two, three or even four in some places). Thus an ounce of silver could exchange for 970 in one city and 990 in the next. In some places in the North of China short of currency the custom counted one cash as two and fewer than 500 cash would be exchanged for an ounce of silver. A string of cash weighed over ten pounds and was generally carried over the shoulder. (See Hosea Morse's "Trade and Administration of the Chinese Empire" p. 130 ff.) Paper money equivalents known as flying cash sometimes showed pictures of the appropriate number of cash coins strung together.
Chinese historian Peng Xinwei stated that in the year 1900 traditional cast copper-alloy cash coins only made up 17.78% of the total Chinese currency stock, privately-produced banknotes made up only 3%, and foreign trade dollars circulating in China (which mostly included the silver Mexican peso) made up 25% of the total Chinese currency stock by the 1900s. The context of traditional Chinese cash coins in the Chinese economy during the 1900s and its late stage in the monetary history of China is comparable to that of Western Europe’s tiered currency systems used prior to the steam-powered mints, struck coinage, and territorial nation-state currencies between the 13th and 18th century. Helen Dunstan argues that the late-Imperial Chinese polity was much more preoccupied with maintaining national grain reserves and making the price of grain affordable to the Chinese people and the attention of the government of the Qing dynasty to the exchange rate of copper and silver would have to be viewed in this light.
The last Chinese cash coins were struck, not cast, during the reigns of the Qing Guangxu and Xuantong Emperors shortly before the fall of the Empire in 1911, though even after the fall of the Qing dynasty production briefly continued under the Republic of China with the "Min Guo Tong Bao" (民國通寶) coins in 1912, and under Yuan Shikai's Empire of China with the "Hong Xiang Tong Bao" (洪憲通寶) series in 1916. The coin continued to be used unofficially in China until the mid-20th century. Vietnamese cash continued to be cast up until the early 1940s. The last Chinese cash coins in Indonesia circulated in Bali until 1970 and are still used for most Hindu rituals today.
Cash coins in the early Republic of ChinaEdit
During the early Republican era a few more cash coins were locally produced until they were finally phased out in favour of the new yuan.

Trial coins with Fujian Sheng Zao (Chinese: 福建省造), Min Sheng Tong Yong (traditional Chinese: 閩省通用; simplified Chinese: 闽省通用), and a Fujian Tong Bao with a reverse inscribed with Er Wen Sheng Zao (Chinese: 二文省造) were also cast, but never circulated.
Inscriptions and denominationsEdit
The earliest standard denominations of cash coins were theoretically based on the weight of the coin and were as follows:
- 100 grains of millet = 1 zhu (Chinese: 銖; pinyin: zhū)
- 24 zhū = 1 tael (Chinese: 兩; pinyin: liǎng)
The most common denominations were the ½ tael (Chinese: 半兩; pinyin: bànliǎng) and the 5 zhū (Chinese: 五銖; pinyin: wǔ zhū) coins, the latter being the most common coin denomination in Chinese history.
From the Zhou to the Tang dynasty the word quán (泉) was commonly used to refer to cash coins however this wasn't a real monetary unit but did appear in the inscriptions of several cash coins, in the State of Yan their cash coins were denominated in either huà (化) or huò (貨) with the Chinese character "化" being a simplified form of "貨" minus the "貝". This character was often mistaken for dāo (刀) due to the fact that this early version of the character resembles it and Knife money was used in Yan, however the origin of the term huò as a currency unit is because it means "to exchange" and could be interpreted as exchanging money for goods and services. From the Jin until the Tang dynasty the term wén (文), however the term wén which is often translated into English as "cash" kept being used as an accounting unit for banknotes and later on larger copper coins to measure how many cash coins it was worth.
In AD 666, a new system of weights came into effect with the zhū being replaced by the mace (qián) with 10 mace equal to one tael. The mace denominations were so ubiquitous that the Chinese word qián came to be used as the generic word for money. Other traditional Chinese units of measurement, smaller subdivisions of the tael, were also used as currency denominations for cash coins.
A great majority of cash coins had no denomination specifically designated but instead carried the issuing emperor's era name and a phrases such as tongbao (Chinese: 通寶; pinyin: tōngbǎo; literally: 'general currency') or zhongbao (Chinese: 重寶; pinyin: zhòngbǎo; literally: 'heavy currency').
Coins of the Qing Dynasty (1644–1911) generally carried the era name of the emperor and tongbao on the obverse and the mint location where the coins were cast in Manchu and Chinese on the reverse.
Cash coins and superstitionsEdit
In Imperial China cash coins were used for fortune-telling, this would be done by first lighting incense to the effigy of a Chinese deity, and then placing 3 cash coins into a tortoise shell. The process involved the fortune teller counting how many coins lay on their obverse or reverse sides, and how these coins scratched the shell, this process was repeated 3 times. After this a very intricate system based on the position of the coins with Bagua, and the Five elements would be used for divination, the Tang dynasty Kai Yuan Tong Bao (開元通寶) coin was the most preferred coin for this usage. Contemporary Chinese intelligentsia found the usage of cash coins for fortune-telling to be superior than any other methods. Other than fortune-telling cash coins were also believed to hold “curing powers” in Traditional Chinese medicine, one method of using cash coins for “medicine” was boiling them in water and let the patient consume that water. Other than that they were also used as “medical tools” particularly in the guāshā (刮痧) method, which was used against diseases like Cholera; this required the healer to scrape the patient's skin with cash coins as they believed that the pathogen remained stagnant underneath the patient's skin in a process called “coining”. Though in general any cash coin could be used in traditional Chinese medicine but the Kai Yuan Tong Bao was most preferred, and preferences were given for some specific coins for certain ailments E.g. the Zhou Yuan Tong Bao (周元通寶) was used against miscarriages.
In modern times though no longer issued by any government, cash coins are believed to be symbols of good fortune and are considered “Good luck charms”, for this reason some businesses hang Chinese cash coins as store signs for “good luck” and to allegedly avoid misfortune similar to how images of Caishen (the Chinese God of Wealth) are used. Cash coins also hold a central place in Feng shui where they are associated an abundance of resources, personal wealth, money, and prosperity. Cash coins are featured on the logos of the Bank of China, and the China Construction Bank.
In Bali it is believed that dolls made from cash coins (or Uang kèpèng) strung together by cotton threads would guarantee that all the organs and body parts of the deceased will be in the right place during their reincarnation. The Tlingit people of the United States of America and Canada used Chinese cash coins for their body armour which they believed would protect them from knife attacks and bullets. One contemporary Russian account from a battle with the Tlingits in 1792 states "bullets were useless against the Tlingit armour", however this would've more likely be attributed to the inaccuracy of contemporary Russian smoothbore muskets than the body armour and the Chinese cash coins sewn into the Tlingit armour. Other than for military purposes the Tlingit used Chinese cash coins on ceremonial robes.
Stringing of cash coinsEdit
The square hole in the middle of cash coins served to allow for them to be strung together in strings of 1000 cash coins and valued at 1 tael of silver (but variants of regional standards as low as 500 cash coins per string also existed), 1000 coins strung together were referred to as a chuàn (串) or diào (吊) and were accepted by traders and merchants per string because counting the individual coins would cost too much time. Because the strings were often accepted without being checked for damaged coins and coins of inferior quality and copper-allots these strings would eventually be accepted based on their nominal value rather than their weight, this system is comparable to that of a fiat currency. Because the counting and stringing together of cash coins was such a time consuming task people known as qiánpù (錢鋪) would string cash coins together in strings of 100 coins of which ten would form a single chuàn. The qiánpù would receive payment for their services in the form of taking a few cash coins from every string they composed, because of this a chuàn was more likely to consist of 990 coins rather than 1000 coins and because the profession of qiánpù had become a universally accepted practice these chuàns were often still nominally valued at 1000 cash coins. The number of coins in a single string was locally determined as in one district a string could consist of 980 cash coins, while in another district this could only be 965 cash coins, these numbers were based on the local salaries of the qiánpù. During the Qing dynasty the qiánpù would often search for older and rarer coins to sell these to coin collectors at a higher price.
Cash coins with flower (rosette) holesEdit
Chinese cash coins with flower (rosette) holes (Traditional Chinese: 花穿錢) are a type of Chinese cash coin with an octagonal hole as opposed to a square one, they have a very long history possibly dating back to the first Ban Liang cash coins cast under the State of Qin or the Han dynasty.
Although Chinese cash coins kept their round shape with a square hole from the Warring States period until the early years of the Republic of China, under the various regimes that ruled during the long history of China the square hole in the middle experienced only minor modifications such as being slightly bigger, smaller, more elongated, shaped incorrectly, or sometimes being filled with a bit of excess metal left over from the casting process. However, for over 2000 years Chinese cash coins mostly kept their distinctive shape. During this period a relatively small number of Chinese cash coins were minted with what are termed "flower holes", "chestnut holes" or "rosette holes", these holes were octagonal but resembled the shape of flowers. If the shape of these holes were only hexagonal then they were referred to as "turtle shell holes", in some occidental sources they may be called "star holes" because they resemble stars. The exact origin and purpose of these variant holes is currently unknown but several hypotheses have been proposed by Chinese scholars. The traditional explanation for why these "flower holes" started appearing was accidental shifts of two halves of a prototype cash coin in clay, bronze, and stone moulds, these shifts would then produce the shape of the square hole to resemble multiple square holes placed on top of each other when the metal was poured in. A common criticism of this hypothesis is that if this were to happen then the inscription on the coin would also have to appear distorted, as well as any other marks that appeared on these cash coins, however this was not the case and the "flower holes" are equally distinctive as the square ones.
Under Wang Mang's Xin dynasty other than cash coins with "flower holes" also spade money with "flower holes" were cast. Under the reign of the Tang dynasty the number of Chinese cash coins with "flower holes" started to increase and circulated throughout the entire empire, concurrently the casting of Chinese cash coins was switched from using clay moulds to using bronze ones, however the earliest Kaiyuan Tongbao cash coins were still cast with clay moulds so the mould type alone cannot explain why these "flower holes" became increasingly common. As mother coins (母錢) were used to cast these coins which were always exact it indicates that these "flower holes" were added post-casting, the largest amount of known cash coins with "flower holes" have very prominent octagonal holes in the middle on both sides of the coin, comparatively their legends are usually as defined as they appear on "normal cash coins", for this reason the hypothesis that they were accidentally added is disproven. All sides of these coins (either octagonal with "flower holes" or hexagonal with "turtle shell holes") are clearly contained inside of the cash coin's central rim. After the casting of cash coins had shifted to using bronze moulds these coins would appear as if they were branches of a "coin tree" (錢樹) where they had to be broken off, all excess copper-alloy had to be manually chiseled or filed off from the central holes. It is suspected that the "flower holes" and "turtle shell holes" were produced during chiseling process, presumably while the employee of the manufacturing mint was doing the final details of the cash coins. As manually filing and chiseling cash coins was both an additional expense as well as time-consuming it is likely that the creation of "flower holes" and "turtle shell holes" was ordered by the manufacturer. However, as the quality of Tang and Song dynasty coinages was quite high it's unlikely that the supervisors would have allowed for a large number of these variant coins to be produced, pass quality control or be allowed to enter circulation. Cash coins with "flower holes" were produced in significant numbers by the Northern Song dynasty, Southern Song dynasty, and Khitan Liao dynasty. Until 1180 the Northern Song dynasty produced "matched cash coins" (對錢, duì qián) which were cash coins with identical inscriptions written in different styles of Chinese calligraphy, after these coins were superseded by cash coins that included the year of production on their reverse sides the practice of casting cash coins with "flower holes" also seems to have drastically decreased. Due to this one hypothesis states that "flower holes" were added to Chinese cash coins to signify a year or period of the year or possibly a location where a cash coin was produced.
It is also possible that these "flower holes" and "turtle shell holes" functioned as Chinese numismatic charms, this is because the number 8 (八, bā) is a homophonic pun in Mandarin Chinese with "to prosper" or "wealth" (發財, fā cái), while the number 6 (六, liù) is a Mandarin Chinese homophonic pun with "prosperity" (祿, lù). Concurrently the Mandarin Chinese word for as "chestnut" (栗子, lì zi) as in the term "chestnut holes" could be a homophonic pun in Mandarin Chinese with the phrase "establishing sons" (立子, lì zi), which expresses a desire to produce male offspring.
The practice of creating cash coins with "flower holes" and "turtle shell holes" was also adopted by Japan, Korea, and Vietnam, however cash coins with these features are extremely rare in these countries despite using the same production techniques which further indicates that their addition was wholly intentional.
Red cash coinsEdit
"Red cash coins" (Traditional Chinese: 紅錢) are the cash coins produced in Xinjiang under Qing rule following the conquest of the Dzungar Khanate by the Manchus in 1757. While in Northern Xinjiang the monetary system of China proper was adopted in Southern Xinjiang where the pūl (ﭘول) coins of Dzungaria circulated earlier the pūl-system was continued but some of the old Dzungar pūl coins were melted down to make Qianlong Tongbao (乾隆通寶) cash coins, as pūl coins were usually around 98% copper they tended to be very red in colour which gave the cash coins based on the pūl coins the nickname "red cash coins". In July 1759 General Zhao Hui petitioned to the Qianlong Emperor to reclaim the old pūl coins and using them as scrap for the production of new cash coins, these "red cash coins" had an official exchange rate with the pūl coins that remained in circulation of 1 "red cash" for 2 pūl coins. As Zhao Hui wanted the new can coins to have the same weight as pūl coins they weighed 2 qián and had both a higher width and thickness than regular cash coins. Red cash coins are also generally marked by their rather crude craftsmanship when compared to the cash coins of China proper. The edges of these coins are often not filed completely and the casting technique is often inaccurate or the inscriptions on them seemed deformed.
At the introduction of red cash system in Southern Xinjiang in 1760, the exchange rate of standard cash (or "yellow cash") and "red cash" was set at 10 standard cash coins were worth 1 "red cash coin". During two or three subsequent years this exchange rate was decreased to 5:1. When used in the Northern or Eastern circuits of Xinjiang, the "red cash coins" were considered equal in value as the standard cash coins that circulated there. The areas where the Dzungar pūls had most circulated such as Yarkant, Hotan, and Kashgar were the sites of mints operated by the Qing government, as the official mint of the Dzungar Khanate was in the city of Yarkent the Qing used this mint to cast the new "red cash coins" and new mints were established in Aksu and Ili. As the Jiaqing Emperor ordered that 10% of all cash coins cast in Xinjiang should bear the inscription "Qianlong Tongbao" the majority of "red cash coins" with this inscription were actually produced after the Qianlong era as their production lasted until the fall of the Qing dynasty in 1911 making many of them hard to attribute.
