String of cash coins (currency unit)


A string of cash coins refers to a historical Chinese, Japanese, Korean, Ryukyuan, and Vietnamese currency unit that was used as a superunit of the Chinese cash, Japanese mon, Korean mun, Ryukyuan mon, and Vietnamese văn currencies. The square hole in the middle of cash coins served to allow for them to be strung together in strings, the term would later also be used on banknotes and served there as a superunit of wén.
Prior to the Song dynasty strings of cash coins were called guàn, suǒ, or mín, while during the Ming and Qing dynasties they were called chuàn or diào. In Japan and Vietnam the term "貫" would continue to be used until the abolition of cash coins in those respective countries.
During the Qing dynasty a string of 1000 cash coins and valued at 1 tael of silver, 1000 coins strung together were referred to as a chuàn or diào 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 would string cash coins together in strings of 100 coins of which ten wouldn 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.
The number of cash coins which had to be strung together to form a string differed both from region to region as time period or by the materials used to manufacture the cash coins, for example under the reign of the Tự Đức Emperor of the Nguyễn dynasty one string of cash coins included 600 zinc coins, while during later days of the French colonial period a string of cash coins was 500 copper-alloy coins. In Vietnam a string of cash coins had the nominal value of 1 Mexican peso or 1 French Indochinese piastre. During the late 19th century in Qing China some currency systems were named after how many cash coins made up a string such as the Jingqian or Zhongqian which was an exchange rate that was used in the capital city of Beijing, the Jingqian system allowed a nominal debt of 2 wén could be paid out using only one physical cash coins instead of two, in this system a string of Beijing cash coins required only 500 cash coins as opposed to the majority of China which used 1000 cash coins for a string. Meanwhile, in the Dongqian system, an exchange rate used for cash coins in the Fengtian province, only 160 cash coins were needed to make up a string. During the Qing dynasty period the term chuàn was used to designate long strings while the term diào was used to design short strings.
Although the term appeared frequently on banknotes the only cash coin to have ever had the currency unit "String of cash coins" as a part of its inscription was the Nguyễn dynasty era Tự Đức Bảo Sao 1 quán cash coin, which was worth 600 văn.

Background

Much like how cash coins are counted in wén, until the Qin dynasty, China used cowry shells and bronze cowry shells which were denominated in bèi and a string of cowry shells was called a péng. However, it is currently not known how much bèi was in a péng.

Strings of cash coin units during the Qing dynasty

During the Qing dynasty different number of cash coins were used to make up strings of cash coins.
In actual circulation, however, cash coins throughout Chinese history were put on strings in 10 groups of 100 coins each, these strings were separated by a knot between each group. During the Qing dynasty period strings of cash coins rarely actually contained 1000 cash coins and usually had something like 950 or 980 or a similar quantity, these amounts were due to local preferences rather than being random in any form. In the larger cities cash shops would make specific strings of cash coins for specific markets. The cash shops existed because at the time there were many different kinds of cash coins circulating in China including old Chinese cash coins from previous dynasties, Korean cash coins, Japanese cash coins, Vietnamese cash coins, large and small genuine Qing dynasty cash coins, and different kinds of counterfeits, such as illegally private minted cash coins. Some of these strings would contain exclusively genuine Zhiqian, while other strings could contain between 30% and 50% of counterfeit and underweight cash coins. The actual number of cash coins on a string and the percentage of counterfeits in a string was generally known to everyone who resided in that town by the type of knots that were used. Each of these different kind of strings of cash coins fulfilled different functions. For example one string of cash coins was acceptable to be used in a local grain market while it would not be accepted at a meat market, while another type of string was able to be used in both markets while not to pay for taxes. The cash shops sorted all cash coins into very specific categories, then they would make up appropriate kinds of strings that were intended for use in specific markets or to pay for taxes to the government.

Banknotes

During the Song dynasty the first series of standard government Jiaozi notes were issued in 1024 with denominations like 1 guàn, 1 mín, up to 10 guàn. In 1039 only banknotes of 5 guàn and 10 guàn were issued, and in 1068 a denomination of 1 guàn was introduced which became forty percent of all circulating Jiaozi banknotes. The Huizi also continued to use these currency units. Between the years of 1161 and 1166 the government of the Song dynasty had produced 28,000,000 dào in Huizi notes. The exchange rate between Guanzi banknotes and copper cash coins was 1 guàn for 770 wén while huizi notes of the eighteenth production period were valued at 3 guàn for 1 wén. During the last days of the Southern Song dynasty China was suffering from inflation to the poiint that the value of the Huizi had lowered so much that a guàn was only accepted at between 300 and 400 cash coins, which caused people to start hoarding these coins and remove them from circulation which had a devastating effect on the economy. As the Mongols continued marching south the Chinese military required more money causing the government to print an excessive amount of Huizi banknotes. The guàn currency unit would later also be used by the Jurchen Jin dynasty and the Mongol Yuan dynasty on their Jiaochao banknotes, though due to hyperinflation these currencies would not be able to be exchanged with any real cash coins and under Mongol rule non-paper forms of currency were abolished.
From the early fourteenth century to the early sixteenth century in Japan banknotes which were known as "saifu" were used for transactions, payments, and the transfer of funds between remote regions. Most of these saifu banknotes had a value of 10 kanmon, these notes also circulated among the general public.
Under the Ming dynasty the Da-Ming Baochao would also continue using guàn as a currency unit for its denominations. The 1 guàn Da-Ming Baochao banknote was originally good for 1,000 copper-alloy cash coins and had a size of 36.4×22 cm, thus made it the largest Chinese paper banknote ever produced. In the middle of its design was an image of a string of cash coins to show what it was worth. At the bottom of the Da-Ming Baochao banknote was a text which explained that it was issued by the Zhongshusheng, and that it was a valid type of currency used concurrently with copper-alloy cash coins, and that counterfeiters would face a penalty, and those who notified the authorities of counterfeiting would be highly rewarded. Despite originally circulating concurrently with cash coins the Da-Ming Baochao became a fiat currency and would later no longer be able to be exchanged for any actual cash coins.
Privately produced banknotes of the Qing dynasty, as is usual for China, had a great variety of names designating them across the country with names being used such as Zhuangpiao, Pingtie, Duitie, Shangtie, Hupingtie, or Qitie. The denominations used on them varied greatly with some reaching as high as 5 diào.
During the early days of the Republic of China the currency units of chuàn wén and diào wén were still being used on banknotes and zhuangpiao. The Hupeh Provincial Bank, a provincial government-owned qianzhuang created by Zhang Zhidong, issued their own banknotes denominated both in taels and in chuàn, which were known as the Hubei Guanpiao, until 1927.

Bamboo tallies

Some Chinese bamboo tallies, which circulated in the provinces of Jiangsu, Zhejiang, and Shandong from the 1870s until the 1940s, used "strings of cash coins" as a currency unit, but also contained additional inscriptions stating that they would not be paid out in "regular" cash coins. For example, a bamboo tally with the text "串錢壹仟文" could contain the additional information that it if were to be redeemed that it would be paid out in Daqian of "10 cash" coins. This bamboo tally would then be paid out in a string of 100 Daqian of 10 wén.
Below their denominations many bamboo tallies had the Chinese characters xin hao to indicate that the bamboo tally is trustworthy to be worth its stated value.
Another way to indicate what type of cash coins would be paid out is if the bamboo tally did or didn't contain the inscription 10 wén below its top hole. It could then contain an inscription like "串錢貳百文" that would only have to be paid out in a string of 20 cash coins of 10 wén rather than 200 cash coins of 1 wén. The reason why the issuing authorities would do this has to do with the concept of "token" money that the Chinese employed at the time. As the Qing dynasty's government starting manufacturing Daqian since the Xianfeng period that contained high nominal values but had intrinsic values that were only slightly more valuable than the low denomination coinages, the issuer of the Bamboo tally would be able to make a profit off of this situation, this was because the bamboo tally in question would be valued more than the promised redeemed value.
In general, bamboo tallies in the region were not always "redeemed" and would continue to circulate in their local areas as a type of alternative currency as long as the local populace would maintain their "trust" that the bamboo token had "value" or "worth". This situation translated into the profits of issuing the tally was kept by the issuing authority. And if the bamboo tally were to be redeemed the redeemer would receive a weight of bronze or brass much lower than the bamboo tally's nominal value.

''Kan'' (weight unit)

The kan as a Japanese unit of measurement is a bead weight for cultured pearls. kan equals one thousand monme or 3.75 kg. The modern kan was officially established in the Japanese Law of Weights & Measures of 1891. It is still used worldwide as a weight indicator for cultured pearls.

Contemporary Western commentaries on strings of cash coins

Qing dynasty

bicyclist William Sachtleben visited the city of Ghulja in 1892 was preparing to cycle to Beijing but while preparing for his trip together with the Russian consul noted the difficulty in transporting strings of cash coins stating:
Sachtleben noted how there were no money exchange banks in the Chinese interior, of the ability to use and exchange the cash coins Sachtleben noted:
Eventually Sachtleben and the Russian consul managed to exchange the strings of cash coins for silver coins as they were easier to carry on their trip, but noted how the money that they had to carry was much heavier than their camera equipment.
British explorer Isabella Bird wrote of the annoyance that strings of cash coins caused to the Chinese she witnessed in her travels stating:

Nguyễn dynasty (French Indochina)

During the colonial era in French Cochinchina Chinese sapèques were exclusively used as casino tokens by gambling houses and weren't used for other purchases unless trade was being conducted with Qing China. The general conversion rate was 1000 lý = 1 lạng = 7.50 French francs. The sapèques which circulated at the time of French Cochinchina were made from zinc and had a very distinctive square centre hole allowing for them to be strung into strings of 1000 zinc sapèques or 600 copper-alloy sapèques, these strings were known as quán tiền in Vietnamese and as ligatures or chapalets in French. Each string is further subdivided into 10 tiền consisting of 60 sapèques, these coins were valued in their quantity rather than in weight. These coins usually featured the reign or era title of the reigning Nguyễn monarch and were extremely poorly manufactured with bad alloys causing the strings to often break with many sapèques breaking resulting in considerable losses for their owners due to their brittleness. Charles Lemire described the heavy nature and difficult mobility of strings of sapèques as "a currency worthy of Lycurgus of Sparta" and non numerantur, sed ponderantur.
To the French zinc coinage also presented a huge in inconvenience since their colonisation of Cochinchina in 1859 as the exchange between French francs and zinc Tự Đức Thông Bảo văn meant that a large amount of zinc coins were exchanged for the French franc. Zinc cash coins often broke during transportation as the strings that kept them together would often snap the coins would fall on the ground and a great number of them would break into pieces, and these coins were also less resistant to oxidation causing them to corrode faster than other coinages.
Prior to 1849 brass coins had become an extreme rarity and only circulated in the provinces surrounding the capital cities of Vietnam, but under Tự Đức new regulations and standards for copper cash coins were created to help promote their usage. Between 1868 and 1872 brass coins were only around 50% copper, and 50% zinc. Due to the natural scarcity of copper in Vietnam the country always lacked the resources to produce sufficient copper coinage for circulation.
