[Edit this paragraph] At the end of the Western Han Dynasty, Wang Mang's regime was cast with a strange shape, which was divided into two parts: the upper part was a round copper coin with a square hole and the lower part was a knife shape. [Edit this paragraph] The coin has a shape of 502 words, with a total length of 7.3 cm and a weight of about 16.4 g.. Under Xin Mang's monetary system, there are 500 "five baht" currencies. People are unwilling to use it, and it will be abolished soon. Switch to the "six springs and ten cloth" system. [Edit this paragraph] There are still many situations, such as Wang Mang's "One Knife and Five Thousand". Because of its special shape and excellent casting, it is favored by collectors and still maintains a high price. 5000 yuan to 10000 yuan each. Good luck.
