Ancient silver coins. Silver coins were first used in the Spring and Autumn Period and the Warring States Period. At that time, silver coins were cloth-shaped, plate-shaped and round-cake-shaped. After Qin Shihuang unified the currency, he ordered that silver should not be used as the currency. There were a few silver coins in Wei, Jin, Sui and Tang Dynasties. In the Song Dynasty, the scope and quantity of the use of silver greatly increased, and the status of silver in circulation surpassed that of gold.

By the end of the Song Dynasty, it was abolished. Paper money was widely used in the Yuan Dynasty. After the Ming Dynasty, silver gradually became a common currency. In Qing dynasty, silver was the main factor, supplemented by copper. From the late Qing Dynasty to the Republic of China, many kinds of silver coins were issued in various places. Ancient paper money. Jiaozi in the Northern Song Dynasty was the earliest paper money in China and even in the world.

Paper money was mainly used in the yuan dynasty, and the yuan system was adopted in the early Ming dynasty. The "Daming Treasure Banknote" issued during the Hongwu period in Ming Taizu is made of mulberry paper, which is one foot high and six inches wide, and is the largest banknote in China.

In the early Qing Dynasty, no paper money was printed. Later, due to national difficulties, "household paper money" was issued, referred to as "official paper money". Later, the "Bao Qing Banknote", referred to as "Bao Banknote", was issued, and its denomination was complicated, which quickly depreciated sharply. By the end of Xianfeng, official tickets had become waste paper, and treasure banknotes were always worth only two or three articles. After Tongzhi stopped using paper money, copper coins were still used.
