Money is money, which is legal tender and can only be issued by the state, namely the People's Bank of China.

This is a chapter, which belongs to handicrafts and can be said to be worthless. If the workmanship is good and the design is good, you can refer to dozens of pieces, but they are only handicrafts, not commemorative coins.

Pay attention to official website of China People's Bank, and there will be an announcement when issuing commemorative coins.
