Coin rating is a process of determining the old and new degree of a coin, which is a relatively subjective process. Traditionally, people often use vague words such as getting better and better coins to describe the appearance of a coin.

Because the newness of coins has a great influence on the currency value, the simple lack of standardized description of coins is obviously not conducive to the market transaction of collecting coins. After long-term development, people have gradually established a set of relatively objective and standardized coin rating standards, which originated in the United States and has been widely promoted around the world.

1. The first set of fixed banknotes in China. China's first set of RMB banknotes.

Since 1948 China People's Bank issued the first set of RMB, five sets of RMB have been issued so far. The fourth set of rating notes is the first series of rating notes since the founding of New China. Including 1 jiao to 100 yuan * * * all nine denominations.

At the same time, the fourth set of RMB-rated banknotes is the only set of coins issued in the form of rating, and it is the most authoritative and influential banknote variety at present, which has extraordinary significance in the history of currency issuance in China.

2. Commemorating the 30th anniversary of the fourth set of RMB circulation.

It has been 30 years since the fourth set of RMB came out. With the improvement of people's living standards, the use of small banknotes has decreased, and the loss rate has been high. However, due to the accelerated frequency of use, large bills have been seriously worn, and new bills or good quality are rare.

The collection of the fourth set of RMB-grade banknotes conforms to the current situation and solves the huge market demand of less genuine products and less good products. The People's Bank of China issued the fourth collection to commemorate the 30th anniversary of RMB circulation.
