There was no silver circulation in the Tang Dynasty, and the settlement was mainly copper coins. In the Tang Dynasty, each Kaiyuan Bao Tong copper coin was 8 cents in diameter, 10 pieces weighed 1 2 pieces, and 1,000 pieces weighed 6 Jin 4 liang. During the Zhenguan period of Emperor Taizong, material civilization was extremely rich. Usually, one or two taels of silver can be converted into 1 0,000 copper coins (also called consistency), so you can buy 200 taels of rice, and 10 taels is one stone, which is 20 taels. In the Tang Dynasty, a stone was about 59 kilograms. Based on the average rice price 1.75 yuan a catty, one or two pieces of silver are equivalent to RMB. During the Kaiyuan period of Emperor Xuanzong of the Tang Dynasty, the price of rice rose to 10, which was also one or two pieces of silver = 2065 yuan.
Generally, the price of silver is now converted into rice, and modern rice is cheap and expensive in ancient times. In addition, due to geographical differences, rice price fluctuations, weight conversion and other factors. The price should be discounted. Moreover, in ancient times, money was usually not exchanged for a penny or two, and it often cost 12300 yuan or more to exchange money. So this conversion is not very accurate. It can be roughly judged that the purchasing power of one or two pieces of silver in the prosperous times is between 2000 and 5000 yuan, and one or two pieces of silver
