Silver is a monetary unit with silver ingots as the main form. Originated in the Han Dynasty and prevailed in the Ming and Qing Dynasties. As legal tender unit, it ends with 1933. People after 1933 still use it. Modern silver can be divided into real silver and virtual silver.
True silver refers to the actual circulation of silver, which can be roughly divided into four types: ingot, medium ingot, small ingot and broken silver. Due to different regions and users, there are more than 70 kinds of silver weights, including Kuping, Guangping, Guanping and Cao Ping. In the thirty-fourth year of Guangxu (1908), the Qing government stipulated that Kuping 1 was equal to 37.438+0g.
