Yuan dynasty coinage
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 (from previous Chinese dynasties), while they immediately abolished the Jin dynasty's paper money as it suffered heavily from inflation due to the wars with the Mongols.
