| Additional information |
Issued by imperial decree in 758 under Emperor Suzong as an emergency fiscal measure during the An Lushan Rebellion, the Qianyuan Zhongbao was assigned a face value of ten cash — ten times a standard single-cash piece — while containing far less than ten times the copper. The scheme was a deliberate debasement, and the population knew it. Merchants refused the coins at face value almost immediately, and within months a second variety valued at fifty cash was introduced, compounding the problem.
The resulting monetary chaos forced a formal revaluation in 759, collapsing the ten-cash piece to a single-cash in official exchange. Production ceased shortly after.
