Xin dynasty
Spade money () was an early form of coin and commodity money used during the Zhou dynasty of China (1045 to 256 BC). Spade money was shaped like a spade or weeding tool. Under the Xin dynasty created by Wang Mang spade money was reintroduced; there were 12 different types of spade money in the Xin dynasty, ranging in values from 100 to 1000 "qián".
