Spade money


Spade money was an early form of coin used during the Zhou dynasty of China (1045 to 256 BC). Spade money was shaped like a spade or weeding tool.

Hollow-handled spades (Chinese: 布幣; pinyin: bùbì) are a link between weeding tools used for barter and stylised objects used as money. Although flimsy, it retains the hollow socket by which a genuine tool could be attached to its handle. This socket is rectangular in its cross-section and still retains the clay from the casting process. In the socket, the hole that fixes the tool to its handle is also reproduced.

The inscriptions on these coins usually consist of one character, which can be either a number, a cyclical character, a place name, or the name of a clan. The crude writing is that of the artisans who made the coins, not the more careful script of the scholars who wrote the votive inscriptions on bronze. The style of writing is consistent with that of the middle Zhou period. Over two hundred inscriptions are known. Many have not been fully deciphered. The characters can be found on the left or right of the central line and may be inverted or retrograde. The alloy of these coins is typically 80% copper, 15% lead, and 5% tin. They are found in hoards of hundreds rather than thousands, sometimes tied together in bundles. Although there is no mention in the literature of their purchasing power, it is clear that they were not small change.

Flat-handled spade money does not have the hollow handle of the early spades. Nearly all have distinct legs, suggesting that their pattern was influenced by the pointed shoulder hollow-handled spades with further styling for easy handling. They are generally smaller and sometimes have denominations specified in their inscriptions in addition to place names. In combination with the little evidence of establishment dates of some mint towns, flat-handled spade money could have been a later development. Archaeological evidence dates them to the Warring States period (475 to 221 BC). Arched foot spades have an alloy consisting of about 80% copper; for other types the copper content varies between 40% and 70%.
