在古玩市场中钱币的存世数量决定其价格，“物以稀为贵”;既要看年代是否久远、流通时间的长短，更要看存世量的多少。我国钱币有近5000年的历史，从先秦到清代货币，品种有数万种之多。先秦货币如齐、燕、赵国的刀币等，由于年代久远存世数量稀少而价格昂贵。

In the antique market, the price of coins is determined by the number of coins in existence, and "the rarity is the most expensive". It depends not only on the age and circulation time, but also on the quantity of coins in the world. Chinese coins have a history of nearly 5000 years. From the pre Qin Dynasty to the Qing Dynasty, there are tens of thousands of kinds of coins. The currency of the pre Qin Dynasty, such as the Dao coin of Qi, Yan and Zhao, was expensive because of its long history and few quantity.

The period of the Republic of China is not only a witness of the prosperity and decline of ancient Chinese feudal dynasty, but also a pioneer who opened the door of the world and knocked on the modern process. During this period, the Double Flag coin came into being. It was not only a witness of the founding of the Republic of China, but also a currency in circulation, a commemorative coin with historical significance, and its status was extraordinary. The biggest difference between the coins issued by the Republic of China and that of the Qing Dynasty is that the dragon pattern was replaced by the Jiahe pattern composed of rice ears, and most of the coins cast in various provinces were the cross of two sides of the national flag.
