Jin dynasty coinage (1115–1234)



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 (which later evolved into the Yuan dynasty; further reading: Yuan dynasty coinage).

History
Although the Jin dynasty had started issuing paper Jiaochao in 1154, they didn’t produce coins until the year 1158, prior to that coins from the preceding Liao and Song dynasties continued to circulate within Jurchen territory, as well as a continuing large inflow of coins produced by the Song, this was because the territory of the Jin didn't have enough copper to meet the demand. Jin era coins circulated alongside paper money and silver sycees, and were the main medium of exchange for the general population.

In the beginning iron coins continued to circulate but this had become to be perceived as an inconvenience so the Jin government ordered the immediate ban on melting down copper for usage other than currency, and was quick to open more copper mines to manage the production of copper coinage. 3 mints were opened that together produced 140,000 strings of coins a year (or 140,000,000 cash coins annually), after inflation had become a problem this production became less profitable for the Jin government.

Coins produced by the Jin dynasty compared to earlier Liao dynasty coinage are both of higher quality, and quantity; this is because the Jurchens chose to model their coins more closely after the Song’s both in production as superficially in its calligraphic style. The Taihe Zhongbao (泰和重寶) were cast with a very special and particular style of calligraphy known as jade tendon seal script.

Due to the constant Mongol invasions and high military expenditures, coins cast after 1209 had become a rarity.

Eastern Xia coinage
According to information from an attempted seller, in a small coin hoard in the Russian Far East in 2011 new seven cash coins were discovered, these coins bore the inscription Dongzhen Xingbao (東眞興寶) alluding to a rebel state named Eastern Xia that was founded during the Mongol conquest of the Jin dynasty.
