Wen │ Yin Bo
During the sixteen years of Wang Mang's usurpation of han rule, he carried out four currency reforms. According to the history books, the Zhou Chamber minted money to "treasure in gold, good for swords, flowing in springs, cloth in cloth, and bundled in the drapery", and Wang Mang asked the ancient system to reform the system to prove that he was the orthodox status of the descendants of the Zhou royal family. During the third reform, Wang Mang introduced the treasure goods system, six major types of currencies in parallel, and the Zizhi Tongjian Han Ji Han Ji Twenty-Nine records: "All treasure goods have five things, six names, and twenty-eight products." Among the eighteen products, "six goods of money, one product of gold, two products of silver goods, four products of turtle goods, five products of shell goods, and ten products of cloth goods." The "six products of money goods" are six springs (50 daquan, 40 zhuangquan, 30 middle springs, 20 young springs, 10 springs, and 10 koizumi naoichi), and the "ten products of cloth goods" are ten cloths (100 small cloths, 200 mobu, 300 young cloths, 400 preludes, 500 poor cloths, 600 zhongbu, 700 zhuangbu, 800 dibu, 900 subbu, and 900 large cloth yellow thousand). In the cloth goods, the small cloth weighs 15 baht, which is increased by 1 baht in turn, and the large cloth weighs 24 baht. The weight ratio of Kobu to Koizumi is 15:1, but the exchange rate is 1:100. The weight ratio of Obu to Koizumi is 24:1, and the exchange rate is as high as 1:1000. There are many kinds of treasure-based currencies, the value of the currency is chaotic, the changes are frequent, and most of them are large-value currencies with inflated values, resulting in soaring prices, extreme inconvenience to use, and boiling public resentment, which has accelerated the collapse of the new Mang regime.
The national treasure Jin Kui Zhiwan is also a product of Wang Mang's reform. The money has a unique style, the upper part is a square hole round money, the seal book "National Treasure Golden Kuai" four characters, "National Treasure" means the national treasure goods, that is, the common coin, "gold" refers to gold, "匮" is a unit of gold; the lower part is rectangular, the book "Zhiwan", meaning that one coin can be worth five baht ten thousand coins. This coin, whether from the form or text, is not contrary to Mangquan. First, the money is above the circle below and the outer circle is inside, which is in line with Wang Mang's belief in the idea of the five elements of yin and yang; second, its font and writing are similar to those of a knife and five thousand and a knife of more than five hundred, the middle of the word "bao" is written as a double king, representing the dominance of the Wang family, while the middle of the "treasure" character of other coins in the past is written "Wang Miao" or "Wang Er". The money flow copper is uneven, obviously after the molding has not been polished and processed, it is likely that it has not been formally flowed. There are many different views on the nature of this coin, some people say that it is a circulating currency, but because the discount is too high to officially enter the circulation field; others believe that the coin is not a common currency, one is used to record the amount of gold held by Wang Mang, and the other is said to be used for the opening of the furnace and the town treasury. The Book of Han mentions that a pound of gold is worth ten thousand yuan, which is the same as the value of the national treasure, and perhaps the straight money is the voucher for exchanging gold.
Before the founding of the People's Republic of China, only one and a half pieces of money survived in China, half of which was the fragment of the upper part of the collector Liu Yanting recorded in the "Ancient Spring Hui kao", one was excavated in the Weiyang Palace area of Xi'an in the twenty-seventh year of Guangxu (1901), changed hands several times during the Republic of China, appeared in the Hong Kong auction market after the founding of the People's Republic of China, bought by the government, and is now in the National Museum. After 2000, Shaanxi has successively unearthed news of the excavation of the national treasure Jin Kui Zhiwan, but it is difficult to distinguish between true and false.
The national treasure Jinkui Zhiwan is well-cast, the shape is unique, the font is beautiful, and it is rare to pass down the generations, and it is one of the fifty treasures of ancient Chinese money, and it is named the title of "Ancient Money Leader".
