Various commercial banks approved by the state to engage in foreign exchange business, such as China Bank, China Industrial and Commercial Bank, China Agricultural Bank and China Construction Bank. It is illegal to exchange foreign currency in places other than designated foreign exchange banks and legal foreign exchange exchange points.

Domestic convertible foreign currencies mainly include: British pound, Hong Kong dollar, US dollar, Swiss franc, Singapore dollar, Swedish krona, Danish krona, Norwegian krona, Japanese yen, Canadian dollar, Australian dollar, euro, Macao dollar, Philippine peso, Thai baht, New Zealand dollar and Korean won. Other foreign currencies are not convertible in our country.

Therefore, we should be especially wary of some lawless elements selling some old foreign currencies that cannot be used in the market. For example, don't buy old coins from Latin American countries such as Peru and Chile in the 1950s and 1960s to avoid being cheated.

Extended data:

All commercial banks in Chinese mainland do not exchange foreign currency cash, including foreign currency that has stopped circulating, slightly damaged foreign currency and foreign currency of some small currency countries. In Chinese mainland, there are a large number of valuable foreign banknotes with small face value, slight damage and small currency value.

Through the secured transaction function of Alipay, the leading independent third-party payment platform in China, these valuable banknotes will be returned to the issuing country through legal channels, thus reducing the people's unnecessary foreign exchange settlement losses.
