Monies of Account and Monetary Transition in China, Twelfth to Fourteenth Centuries.

Between the twelfth and the fourteenth centuries China's monetary system shifted from a multiple currency system including paper notes, bronze coin, and uncoined silver to a unified paper currency system established by the Mongol Yuan dynasty. Consequently, China's long-standing bronze coin standard was replaced by a new money of account denominated in silver. However, silver largely disappeared as a medium of exchange under Yuan rule.
