[1][need quotation to verify] The majority of cash coins in circulation at the time of the Ming were actually from the Tang (618 to 907) and Song dynasty (960 to 1279) eras.
Meanwhile, the return route also ensured constant supply of the Spanish silver dollar coins which were minted in New Spain (Mexico), and mined from Potosí in Bolivia or Peru.
[7] After the Chinese became independent following the retreat of the Mongols back north and a bloody civil war culminating with the victory of Zhu Yuanzhang the Ming dynasty rose to power and under it a long period of stability and growth came.
[11] The term "Zhiqian" (制錢) was used to discern full-valued cash coins produced by the imperial government from older ones from the Song dynasty period, which were known as jiuqian (舊錢), and privately produced forgeries of non-standard weights and alloys that were referred to as siqian (私錢) or sizhuqian (私鑄錢).
[8] and Shangqian (賞錢, "Tip money") which is a term used to refer to cash coins that were small, thin, and very fragile (comparable to Sizhuqian) that were used to pay the wages of employees of the imperial government (including the mint workers themselves) and was one of the most commonly circulating types of cash coins during the Ming dynasty among the general population.
[11] The raw material copper that was necessary for the production of Ming dynasty cash coinage came from mines in the provinces of Jiangxi, Shaanxi, and Shanxi.
[11] Despite the government preferring paper money over copper-alloy cash coins, the Chinese market had a high demand for them, this demand would stimulate an overproduction of forgeries that inundated the markets of Ming China, often these forged cash coins were cast in such miserable quality that a single real Zhiqian could buy 300 fake ones.
[12] These cash coins with the inscription Taichang Tongbao (泰昌通寶) were produced by his son, the Tianqi Emperor, in large quantities as a sign of filial piety.
[11] Chinese people at this point started to refrain from using copper-alloy cash coins and the markets preferred the usage of silver ingots instead.
[13] The government granted him permission to cast 10 wén cash coins leading to debasement, in 1622 their production had ceased.
[15] An example of these Chongzhen Tongbao cash coins with mint marks the Chinese character "Zhong" (忠) which translates as either "loyal" or "honest" located above the reverse side of the square centre hole.
[15] No coins with the inscription Zheng De Tong Bao (正德通寶) were ever produced for circulation by the Zhengde Emperor, however during the late Ming, and early Qing era many "lucky charms" with this inscription were produced, but these usually contain more decorative reverses featuring various auspicious depictions.
[17] No cash coins are known to have been cast and put into general circulation with the following seven Ming dynasty period reign titles:[15] Jianwen (建文), Hongxi (洪熙), Zhengtong (正统), Jingtai (景泰), Tianshun (天顺), Chenghua (成化), and Zhengde (正德).
[18][19] "Hong Xi Tong Bao" (洪|熙通寶) was produced in 1425, during Hongxi years, when Zhu Gaochi was the emperor of Ming.
After Zhu Di came to the throne, he carried out a series of reforms covering all fields, including politics, economy, culture, military and diplomacy.
[35] "Xing Chao Tong Bao" (興|朝通寶) was produced by Sun Kewang, in 1649 (sixth year of Shunzhi), when he became the Dongping King.
[36] At that time, Sun produced a large number of "Xing Chao Tong Bao" and it had its distinct features with a profound influence.
"Da Shun Tong Bao" was often sewn onto clothing as a sort of celebration to the peasant rebel army.
