Qing dynasty coinage
Qing dynasty coinage was based on a bimetallic standard of copper and silver coinage. The Manchu-led Qing dynasty was proclaimed in 1636 and ruled over China proper from 1644 until its overthrow in 1912 as a result of the Xinhai Revolution. The Qing saw the transformation of a traditional cash coin–based cast coinage monetary system into a modern currency system with machine-struck coins, while the old traditional silver ingots would slowly be replaced by silver coins based on those of the Mexican peso. After the Qing dynasty was abolished, its currency was replaced by the Chinese yuan of the Republic of China.
