At that time, the earliest paper money in the world was in the Song Dynasty. At that time? Sex? It has been widely used in the folk, and it is very convenient to use, because carrying copper coins with you is very heavy, and the use of paper money makes people more convenient.
(Song Jiaozi)
During the Spring and Autumn Period and the Warring States Period, in order to adapt to the development of commodity economy, various ancient coins began to appear in various vassal States, most of which were modeled after the tools of production and life at that time.
For example, the ancient coins of Chu state have developed from Beibi to literally Beibi, which are called flour money and ant nose money. The ancient coins in the Central Plains have different shapes. For example, in the northern coastal areas, the shape of knife coins evolved from the fishing and hunting tool-knife cutting.
After Qin Shihuang unified the six countries, he agreed to the monetary policy in order to consolidate his rule and develop the economy. He extended half a penny from the outer circle to the whole country. This is the first monetary reform in China's history. This kind of copper coin has solved the complicated and inseparable currency problems of various countries and formulated the weight and form to meet the needs. This kind of money is a milestone in the history of coin development in China, which indicates that the form of the outer circle and the inner side has been stereotyped since then, and it has continued until the end of the Qing Dynasty. The shape of the inner side of the outer circle also conforms to China's philosophy of round place since ancient times.
In the Han Dynasty, the commercial economy gradually improved and the coin system began to reform. Five baht coins were minted in 65438 BC+065438 BC+08 BC, and continued to the Sui Dynasty. In the Song Dynasty, the raw materials of coins were both copper and iron, and the commercial development of the Song Dynasty reached a new height. At this time, the circulation of coins was more severe, so the number of coins cast by the court was quite amazing. There were forty or fifty kinds of annual money among more than a dozen emperors in the Song Dynasty. The back of the coin is engraved with Xichun Bao Tong, who was cast in the seventh year of Xichun in the Southern Song Dynasty. Hey? The word is calendar year, that is, the so-called calendar year money. This currency year system became popular at the end of the Song Dynasty, more than 300 years earlier than the European calendar year money. Because the Yuan Dynasty and the early Ming Dynasty mainly used paper money, but less copper coins were cast, there was no groundbreaking reform on the shape of copper coins in the early Yuan Dynasty and the early Ming Dynasty. After the mid-Ming Dynasty, silver became a common currency. Due to the increase of purchasing power, copper coins are no longer suitable for high-value goods, so higher-priced goods are usually bought with silver, and copper coins are only used for small payments, but the court still has not stopped issuing copper coins. In the Qing Dynasty, after seeing the western coinage technology, Zhang Zhidong bought a coinage machine from England and set up a mint in Guangzhou. China began to make coins by machine for the first time. At this point, the mechanism currency officially entered the monetary field of our country, saving a lot of character costs. Coin, as a microcosm of a country's historical development, can witness the economic development of ancient society, while China's coins can more comprehensively explain the development history of coin culture with oriental characteristics. Because of their historical value, more and more people like to collect these ancient coins.
