The Da-Qing Tongbi (Traditional Chinese: 大清銅幣), or the Tai-Ching-Ti-Kuo copper coin, refers to a series of copper machine-struck coins from the Qing dynasty produced from 1906 (Guangxu 31) until the fall of the Qing dynasty in 1911. These coins were intended to replace the earlier cast cash coins and provincial coinages, but were welcomed to mixed receptions.
