A sycee (; from Cantonese , , ) or yuanbao () was a type of gold and silver ingot currency used in imperial China from its founding under the Qin dynasty until the fall of the Qing in the 20th century. Sycee were not made by a central bank or mint but by individual goldsmiths or silversmiths for local exchange; consequently, the shape and amount of extra detail on each ingot were highly variable. Square and oval shapes were common, but boat, flower, tortoise and others are known. Their value—like the value of the various silver coins and little pieces of silver in circulation at the end of the Qing dynasty—was determined by experienced moneyhandlers, who estimated the appropriate discount based on the purity of the silver and evaluated the weight in taels and the progressive decimal subdivisions of the tael (mace, candareen, and cash).
