The paper money of the Qing dynasty (Traditional Chinese: 清朝鈔票) was periodically used alongside a bimetallic coinage system of copper-alloy cash coins and silver sycees; paper money was used during different periods of Chinese history under the Qing dynasty, having acquired experiences from the prior Song, Jin, Yuan, and Ming dynasties which adopted paper money but where uncontrolled printing led to hyperinflation. During the youngest days of the Qing dynasty paper money was used but this was quickly abolished as the government sought not to repeat history for a fourth time; however, under the reign of the Xianfeng Emperor, due to several large wars and rebellions (most notably the Taiping Rebellion), the Qing government was forced to issue paper money again.
