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. One early period example is the Bronze 1 cash.

Zhu Yuanzhang, better known as the Hongwu Emperor, proclaimed the Ming in 1368. It was originally based at Yingtian (now Nanjing) before being moved to Beijing by the Yongle Emperor in 1421.
From the founding of Ming until 1450, the emperors attempted to use paper currency, but this experienced the same hyperinflation as its predecessors. For the most part, the country was starved for silver in the early part of the dynasty and much trade occurred via barter; in later years, silver from Japan and Spain (through the Manila Galleon) flowed into the country and were traded as bullion now known as sycee. However, the emperors also periodically minted coins. Alongside copper coins cowrie shells continued to circulate during this period as well.
