Later, people switched to bronze as currency, and finally gold, silver, copper coins and silver notes appeared.

However, this currency was too small, too light, and particularly easy to confuse. Therefore, in order to rectify the chaotic monetary system, the emperor chose to abolish the currency of the Sui Dynasty. Kaiyuan Tongbao was minted, and this currency replaced the remaining currencies in society. Then such a currency came into people's sight.
At the beginning, the four characters "Kaiyuan Tongbao" were written by the calligrapher Ouyang Xun.
This currency has lasted for more than 1,300 years. What is even more shocking is that there is a nail mark of the empress on the back of this currency. It turns out that in order to show his favor, Emperor Gaozu of the Tang Dynasty granted permission for his children to mint currency. right. One day, Empress Changsun looked very curious, so she picked it up and looked at it. While viewing it, she accidentally left a trace of her fingernail. The currency was made from molds, leaving a moon-shaped nail pattern.
