Jingyou Yuanbao was minted in the first year of Jingyou (1034) of Renzong in the Northern Song Dynasty. It is nearly a thousand years ago. Your Jingyou Yuanbao is 3 centimeters. The coin spectrum records that the Jingyou Yuanbao is divided into two. There are only iron coins, and the diameter is about 3.2 centimeters. If the diameter of your coin is less than 2.8 centimeters, it is a small flat coin, and the market price is one or two yuan. If the diameter is larger than 3 centimeters, it should be discounted by two cents. , if it is not an iron coin, it may be an iron-eye coin. Ruan Shengzu (1820-1841), the monarch of the Ruan Dynasty in Vietnam, cast Mingming Tongbao Xiaoping copper coins and zinc coins, and began to cast large coins with beautiful names. The coin is made of beautiful copper and has the inscription "Ming Ming Tong Bao" on the front. On the back, characters reflecting Confucianism from the traditional Chinese classics Four Books and Five Classics are selected as inscriptions. Those with four characters and eight characters are considered rare when one is equivalent to a hundred. During the Jialong and Mingming periods, zinc money was vigorously promoted, especially when Emperor Mingming "used lead money. Rich households did not dare to keep it secretly, and businessmen from neighboring countries did not dare to bring it back."
The economic thought of "the circulation of this money is not only beneficial to the people, but also beneficial to the country, and it is naturally only beneficial" should be deeply inspired by the monetary policy of lead and iron money by Gao Yu of the Southern Chu Dynasty in the Five Dynasties of China. If you go bareback, it will cost 7--10 yuan
