我国最早从实物货币向金属货币过渡是在商代晚期(约公元前14-11世纪),当时仿海贝形状铸行的“青铜贝币”标志着我国货币开始进入金属货币的阶段。 在我国宋朝铸钱最多且制作最精美。两宋共有18帝57个年号,有48个年号改铸新钱,其中43个年号铸的是年号钱。 The earliest transition from physical currency to metal currency in China was in the late Shang Dynasty (about the 14th to the 11th century BC), when the imitation shellfish shaped bronze coins indicated that China’s currency began to enter the metal currency stage. In our country, the Song Dynasty made the most money and produced the finest. There were 18 dynasties and 57 new years in the two Song dynasties, with 48 new titles rebuilt and 43 new year titles cast by year numbers.
