Stack casting was a main method to mint coins from the Qin and Han dynasties to the Northern and Southern Dynasties. With the stacked pottery fan (mold for casting copper coins), over a hundred of coins could be minted at a time. The production efficiency was higher than vertical casting with sectional molds. This is a mold case for Wuzhu coins minting in the 17th year of the Jianwu period (AD 41). It can be used repeatedly to cast the pottery mold cases. There is the date and other inscriptions on the back of the mold. Wuzhu coins began to be minted in the 16th year of the Jianwu period of Eastern Han (AD 40). This case, dated the 17th year of the Jianwu period, is very valuable for the study of coin minting in the Eastern Han dynasty.
