1, money-making system:

The basic unit is Wen, namely 1 copper coin, which is called "1 coin" or "1 coin". 1 currency has a small currency and is often used together in large quantities. ComMonly used units are mo and Hang.

The standard number of 1 Mo is 100, and the standard number of 1 Hangzhou is 1000, but in fact, since the Southern and Northern Dynasties, Mo and Hangzhou have been shrinking (called "short Mo" or "save Mo"), and by the Northern Song Dynasty, the court clearly stipulated 65,400.

2, silver two systems:

Silver is a very complicated system, and the basic unit is "two". In fact, the weight unit of this kind of silver is slightly different at different times and in different regions. It can be roughly estimated according to 37.5g 1 two materials, 1 two = 16 money. There is also a question about the fineness of silver, which is generally divided into "snowflake silver" (with high fineness). 96%) and mixed silver (generally 90-95%, the lowest is no longer in circulation).

In fact, the banking system and the money-making system are parallel, and there is no fixed distinction between the main currency and the secondary currency, and there is no fixed proportion.

Before and after the Song Dynasty, money was mainly used, and money was seldom used.

The Yuan Dynasty used paper money to make money.

Since the Ming Dynasty, a large amount of silver has been used in daily circulation. In the Ming and early Qing Dynasties, 1 two pieces of silver could be exchanged for about 600-800 words. From the Qianlong period, the money gradually decreased with the inflow of silver, gradually turned into outflow and gradually depreciated. After the Opium War, I often got more than 2,000 pieces!
