1. Knife coins originated in the primitive society of China. Due to the different modes of social production, different currencies were produced as circulation tools. The main features of currency are unified pricing system and easy circulation and carrying. In the pre-Qin period, there were four main forms of money, namely, cloth, shells, coins and knives. Cloth coins are the function of farming civilization, knife coins are the function of fishing and hunting civilization, and the use of shells as money can be traced back to more than 3800 years ago. Another most important money circle is a round coin with a hole in the middle, which can be strung together with cloth.
Second, the development of knife coins The development history of knife coins in China is not very long, and they have been widely used in the Spring and Autumn Period and the Warring States Period. Knife coins first appeared in the state of Qi. Later, due to Qi's constant foreign wars and wars with neighboring countries, the currency of sword currency was spread to other countries, and its circulation scope was expanded. Moreover, due to the different casting areas, different knife coins have been produced, but they can be roughly divided into three series: Qi Dao, Yan Dao and Zhao Dao. And six ancient Dao coins are strung together end to end, just to form a ring. We can also see the ingenious design and supreme wisdom of the ancient people in China.
