Chinese cash coins were minted for more than two thousand years by many of the rulers who have shaped the history of one of the world’s great civilizations. The legends on each coin are easily identifiable and from the mint names, first used regularly by the T’ang emperors, we can trace the expansion of China. The size changes of the coins mark the periods when inflation affected the country. Each of these Chinese cash coins was laboriously hand made by castings in a form that resembles a flattened tree and molten bronze. The circular shape of the coin represented heaven, while the square hole in the center represented the earth. Cash coins were considered a great symbol of wealth and were also worn as amulets against disease, evil or negative energy directed at the wearer.
