First, copper coins, ancient copper coins, refer to all kinds of square hole coins after Qin and Han Dynasties, and the casting period of square hole coins continued until the late Qing Dynasty and the early Republic of China. During the Spring and Autumn Period and the Warring States Period, with the development of commodity economy, the metal weighing currency that needs to be divided and identified in circulation gradually became unsuitable and was replaced by metal coins.
Second, most ancient coins in China are cast in the form of copper alloy, and square hole coins (copper coins) are the most common ones. Chinese ancient coins have a long history, a long history, various varieties and colorful colors, which are the treasures of China traditional culture. For thousands of years, China's monetary culture has condensed the wisdom and talents of the Chinese nation, and created its own, dazzling and unique monetary culture. Ancient coins are also called spring, cloth, silk and Kong Fangxiong.
Third, it has become a new hot spot for collection investment, and many ancient coins stand out in the auction. The collection and appreciation of ancient coins need to master a lot of knowledge, including currency history, numerology, archaeology, epigraphy and cultural relics, ancient Chinese and so on. Some coins look ordinary, but they are actually treasures. Experts can easily get treasures from sellers who don't know much about the value of ancient coins.
Fourth, the square hole copper coin should be said that the sky is round and the ground is square. In ancient times, people thought that the sky was round and the earth was square, so Qin Shihuang made money on this basis. After Qin Shihuang unified China, he also unified the currency. Abolish coins such as knives, cloth and shells, and use "half Liang" as currency. That is to say, the inscription of "Banliang" was cast with the square hole copper coins of the later Qin State, weighing 12 baht (one or two is 24 baht), so it is called "Banliang" copper coins as heavy as its inscription. Since then, this "half-liang" which evolved from a round hole to a ring of money has been circulating in China for more than two thousand years.
Fifth, the square hole coins cast in the Han Dynasty are still called "half Liang", but their weight is decreasing. For example, in the second year of Lv Hou (186), it fell to eight baht, and in the fifth year of Wendi (175), it fell to less than one baht, which is called "pod money". In the first year of Jianyuan (BC 140), Liang Wudi cast another three baht. In the fifth year of Yuanshou (former 1 18), the "half Liang" was abolished, changed to five baht, and the text "five baht" was cast. This five-baht coin began to be used in the Eastern Han Dynasty, and it was followed in successive dynasties until it was abolished in the fourth year of Tang Wude (62 1). It has been used for a long time and its currency value is relatively stable, making it an important coin in the history of China.
6. During Wang Mang's reign as emperor, he implemented the treasure system, called money "spring", and added two sets of coins, "six products of spring goods" and "ten products of cloth goods". Six products of spring goods, also known as "six springs", are the general name of six kinds of round coins in Wang Mang's treasure system. Namely Koizumi, Yaoquan, Youquan, Zhongquan, Zhuangquan and Daquan. Junichiro Koizumi is six points in diameter, weighs one baht, and is worth one penny, with the words "Junichiro Koizumi" on it. Other spring coins have different diameters, weights and values. Liu Quan is a worthless coin, but Koizumi and Daquan are widely circulated.
Seven, ten kinds of cloth goods, also known as "ten kinds of cloth", are also the general name of ten kinds of cloth coins in Wang Mang's guarantee system, namely small cloth, mysterious cloth, young cloth, original cloth, poor cloth, medium cloth, strong cloth, young cloth, secondary cloth and big cloth. The small cloth weighs fifteen baht, is one inch and five minutes long, and is worth one hundred articles. Others are increased by one baht in turn, the length is increased by one point, and the face value is increased by one hundred. The cloth weighs 24 baht, is 2 inches and 4 minutes long, and is worth 1000 pieces, so it has a large circulation. Other fabrics are difficult to identify, easy to confuse and inconvenient to circulate.
Eight, China ancient coins are often named after the year of the emperor, also known as "annual money". It was first cast by Han Cheng in the five lakes and sixteen countries. In 338, Li Shou proclaimed himself emperor in Sichuan, Yunnan, Guizhou and other places. Started casting "Han Hangqian". Soon, in the Southern Song Dynasty, in the first year of Xiao Jian (454), five baht was cast as filial piety, and in the nineteenth year of Taihe (495), Emperor Xiaowen of the Northern Wei Dynasty cast five baht as Taihe. The annual money has been customized since the Song Dynasty. The title of the Song Dynasty changed frequently, and a lot of money was invested in it.
After nine yuan, all the coins in the past dynasties were basically named after the year number. For example, Zhiyuan Bao Tong in Yuan Dynasty, Hongwu Bao Tong in Ming Dynasty and Bao Tong in Gan Long in Qing Dynasty.
