The Qara Khitai, or Kara Khitai, also known as the Western Liao, officially the Great Liao, was a dynastic regime based in Central Asia ruled by the Yelü clan of the Khitan people. Being a rump state of the Khitan-led Liao dynasty, Western Liao was culturally Sinicized to a large extent, especially among the elites consisting of Liao refugees.
There are various kinds of Xinjiang coins produced throughout the history of Xinjiang using the styles of contemporary Chinese cash coins as well as Persian and Islamic coinages. As not many records exist from the ancient monarchies of Xinjiang the study of its coinage has determined when which rules reigned and the state of the economy based on metallurgical analyses.
The cash or qian was a type of coin of China and the Sinosphere, used from the 4th century BC until the 20th century AD, characterised by their round outer shape and a square center hole. Originally cast during the Warring States period, these coins continued to be used for the entirety of Imperial China. 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.
Chinese coinage in the Ming dynasty saw the production of many types of coins. During the Ming dynasty of China, the national economy was developed and its techniques of producing coinage were advanced.
The Yuan dynasty was a Mongol-ruled Chinese dynasty which existed from 1271 to 1368. After the conquest of the Western Xia, Western Liao, and Jin dynasties they allowed for the continuation of locally minted copper currency, as well as allowing for the continued use of previously created and older forms of currency, while they immediately abolished the Jin dynasty's paper money as it suffered heavily from inflation due to the wars with the Mongols. After the conquest of the Song dynasty was completed, the Yuan dynasty started issuing their own copper coins largely based on older Jin dynasty models, though eventually the preferred Yuan currency became the Jiaochao and silver sycees, as coins would eventually fall largely into disuse. Although the Mongols at first preferred to have every banknote backed up by gold and silver, high government expenditures forced the Yuan to create fiat money in order to sustain government spending.
The Southern Song dynasty refers to an era of the Song dynasty after Kaifeng was captured by the Jurchen-led Jin dynasty in 1127. The government of the Song was forced to establish a new capital city at Lin'an which wasn't near any sources of copper so the quality of the cash coins produced under the Southern Song significantly deteriorated compared to the cast copper-alloy cash coins of the Northern Song dynasty. The Southern Song government preferred to invest in their defenses while trying to remain passive towards the Jin dynasty establishing a long peace until the Mongols eventually annexed the Jin before marching down to the Song establishing the Yuan dynasty.
The Western Xia was a Tangut-led Chinese dynasty which ruled over what are now the northwestern Chinese subdivisions of Ningxia, Gansu, eastern Qinghai, northern Shaanxi, northeastern Xinjiang, southwest Inner Mongolia, and southernmost Outer Mongolia from 1032 until 1227 when they were destroyed by the Mongols. The country was established by the Tangut people; likewise its earliest coins were escribed with Tangut characters, while later they would be written in Chinese. Opposed to Song dynasty coins that often read top-bottom-right-left, Western Xia coins exclusively read clockwise. Despite the fact that coins had been cast for over a century and a half, very little were actually produced and coins from Western Xia are a rarity today. Although the Western Xia cast their own coins barter remained widely used.
The Jin dynasty was a Jurchen-led dynasty of China that ruled over northern China and Manchuria from 1115 until 1234. After the Jurchens defeated the Liao dynasty and the Northern Song dynasty, they would continue to use their coins for day to day usage in the conquered territories. In 1234, they were conquered by the Mongol Empire.
Nagasaki trade coins (長崎貿易銭), also known as Nagasaki export coins, refer to Japanese mon coins specifically cast for export by the Tokugawa government between 1659 and 1685 during the Sakoku era. Though the inscriptions on the coins often match Chinese coins from the Song dynasty they’re often cast with different typefaces such as the fact that the Genpō Tsūhō (元豊通寳) produced at Nagasaki was in Clerical script while the Song dynasty’s versions were in Seal script and Running script. Due to the success of these coins they’re often still found in modern day Vietnam and Java, and were copied by contemporary Vietnamese mints as they had become the de facto standard coinage in Vietnam as native production had declined in the 17th century. As the export of gold and silver was banned by the Qing dynasty Japanese merchants were most likely to go to Hanoi and Hội An to gain access to Chinese products causing these coins to start circulating en masse on the Vietnamese market. A special “5 elements” series of Nagasaki trade coins were also cast for export to Taiwan.
Kucha coinage was produced in the Kingdom of Kucha, a Buddhist, Tocharian-speaking state located in the Tarim Basin, during the 1st millennium CE.
The coinage of the Great Shu Kingdom is the earliest known coinage produced by a peasant revolt in the history of China, the revolt lasted from 993 until 995 and during this period a small number of cash coins were produced by the peasant rebellion using the era names of the rebel leader Li Shun. It was only with the strongest military efforts that the Song dynasty was able to suppress the rebellion and restore their rule over the Shu region. The coinage produced by the Da Shu Kingdom is often rather roughly produced and as the rebellion only lasted a few years not many cash coins were produced leading to them being extremely rare today.
The Great Qing Copper Coin, also known as the Qing Dynasty Copper Coin or Da-Qing Tongbi, officially the Tai-Ching-Ti-Kuo Copper Coin, refers to a series of copper machine-struck coins from the Qing dynasty produced from 1906 until the fall of the Qing dynasty in 1911. These coins were intended to replace the earlier cast cash coins and provincial coinages, but were welcomed to mixed receptions.
Bingqian, or Bingxingqian, is a term, which translates into English as "biscuit coins", "pie coins", or "cake coins", used by mainland Chinese and Taiwanese coin collectors to refer to cash coins with an extremely broad rim as, these cash coins can also be very thick. While the earliest versions of the Bingqian did not extraordinarily broad rims.
Iron cash coins are a type of Chinese cash coin that were produced at various times during the monetary history of imperial China as well as in Japan and Vietnam. Iron cash coins were often produced in regions where the supply of copper was insufficient, or as a method of paying for high military expenditures at times of war, as well as for exports at times of trade deficits.
The usage of cash coins in the pseudoscientific practice of traditional Chinese medicine (TCM) are primarily used in two main medical practices, notably coin rubbing and the preparation of "coin teas". Coin rubbing is practiced by ethnic Han Chinese and others in many parts of Southeast Asia and is primarily used as a treatment for "hot" diseases and is related to the more familiar pseudoscientific practices of cupping therapy and acupuncture.
The Zhouyuan Tongbao is a copper-alloy cash coin produced during the reign of Emperor Shizong of the Later Zhou dynasty, a historical Chinese state that existed in the Five Dynasties and Ten Kingdoms period. The design of the Zhouyuan Tongbao cash coins closely resembles that of the Kaiyuan Tongbao (開元通寳) series produced during the earlier Tang dynasty period. The Zhouyuan Tongbao cash coins were produced from recycled Buddhist statues confiscated from Buddhist temples. For this reason the Zhouyuan Tongbao is commonly referred to as "Arhat money" or as the "money that destroyed Buddha". Nicknames only reserved for a handful of Chinese cash coins, as confiscation of Buddhist statues for coin production only happened around 7 times in Chinese history.
Cash coins with flower (rosette) holes are a type of 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 (半兩) cash coins cast under the State of Qin or the Han dynasty. Cash coins are characterised by their round shape and square hole, but Huachuanqian are cash coins with an octagonal hole. These octagonal holes are mostly found in Chinese cash coins, but are in some rare instances also found in Japanese, Korean, and Vietnamese cash coins.
Lead cash coins are a type of Chinese, Japanese, and Vietnamese cash coin that were produced at various times during the monetary history of imperial China, Japan, and Vietnam. Typically cash coins produced in China between 300 BC and 1505 AD were made of bronze and those produced after 1505 AD were made of brass. But, like with iron cash coins, at times when copper was scarce government authorities would produce lead cash coins to supplement the money supply and maintain market liquidity.
