This mould is made of grey clay pottery, with a very detailed structure and four cavities. The top is narrow and the lower portion broad. The left hand side is straight, and the right hand side is curved.
The upper left corner of the mould is marked with the character “jie”(介). Moreover, the inside of the mould has an impression for casting four "Dangjin” spades. The impressions for casting the bu are 8.5 cm long, with two vertical lines through their centers, and two horizontal lines that connect the vertical lines. Each piece of money measures 4. 25 cm long, 2 cm wide, with a 1.1 cm long head. The reverse side of the mould is uneven and has a fingerprint on it.

“Dangjin” were a form of cast metal currency from the state of Chu. This money mould was discovered in Handu, near the bronze-casting workshop of the ancient city of Zhenghan, verifying that this bronze-casting workshop was likely the location where “dangjin” money was produced. This find also verifies that “Dangjin” currency was used in the mid and late Chu state period, primarily circulated through trade in the newly expanded territories and border regions of the state.
