During this period, the early paper money issued by the central bank, the rare legal tender, and the paper money issued by local banks and commercial banks were the most valuable.

1. Early banknotes issued by the central bank, such as Sun Yat-sen's commemorative coins for the founding of the People's Republic of China and foreign tickets with Yuan Shikai's head in the third, eighth and ninth years of the Republic of China, have high collection value because of their age, small circulation and special historical background.

2. Rare edition of legal tender: as the main currency in circulation during the Republic of China, legal tender with different editions, serial numbers, wrong editions and special titles, especially some special commemorative editions issued after the victory of the Anti-Japanese War, has a considerable market price because of its high rarity.

3. Banknotes issued by local banks and commercial banks: Due to the limited circulation, strong regionality and short circulation time, there are very few banknotes issued by local banks and some commercial banks with a long history during the reign of local warlords, such as banknotes issued by the Sichuan military government and banknotes issued by the Jinsui border region.
