Superb quality, rare this nice!
Cowries were used as primitive money in China since the 2nd millenium BC. Later on, bronze cowrie-shaped coins and cowrie-shaped coins made out of carved bone (like this piece) were used as money. This piece is of very nice high quality! The bronze cowries are rare and almost always crude, like this piece. These are rightfully considered to be the very first bronze coinage of China.
This coin is unconditionally guaranteed to be authentic.
