Tongbao became the top ten money in the Great Song Dynasty, and Li Zongbao in the Southern Song Dynasty cast it after July (1225). At that time, "Dasong Yuanbao" coins were used, while "Dasong Bao Tong" only had small iron coins. The bronze man only saw a kind of big money when he picked it up. Very little finishing. "Dangshi" is one inch and six minutes (5.2 cm) in diameter and weighs 30 to 35 grams. Qian Wen's regular script is straight-reading, and his calligraphy is very beautiful, which is characterized by connecting words from the beginning. According to the cloud, it was written by Cai Jing, a great calligrapher in the Song Dynasty. According to Qian Wen's shape, it can be divided into two types: thin books with small characters and thick strokes with large characters, of which thin books are the best. When you collect a lot of money and invest it in Xichuan, it's like a prison in Jiading. There's no way to know how much you voted. Become a rare coin treasure in the world. Li Zuoxian's "Gu Quan Club" has a written description: "Money is recited as ten, which is not included in the history of the Song Dynasty, but was obtained by Lv Yaoxian, which is rare in the Song Dynasty" ("Gu Quan Club" Li See XIV).
65438+In 1930s, Mr. Liu Yanting, a famous economist in Gu Quan, learned that Mr. Qu Mufu had a collection of 1 piece. Picked up a lot of money, praise is a unique product. Qu Mufu (1769- 1844), a native of Jiading, Jiangsu, once collected more than 2,000 pieces of Gu Quan. At that time, Liu Zeng wrote to ask for an extension of ink, but unfortunately he failed to do so. 10 years later, 1847, Liu saw 1 piece of Da Song (word Yaoxian, Bing Shen Jinshi, official worship of Fujian Governor, like to collect ancient mirrors, coins, bricks and other cultural relics). Liu thought that the money collected by Lu was Qu Mufu's old money. Mr. Weng Shupei, an economist in Gu Quan, pointed out in his "Gu Quan Huikao": "What Yao Xian got was not hidden by Li Sheng, so the extension can be known." Qu's big money is said to have been transferred to other people's collections in the eleventh year of Daoguang (183 1), and has since disappeared. After years of circulation, the coins collected by Da Songlu have always been owned by Mr. Li, a family of Tibetan springs. Li once wrote: "The Song Dynasty should have collected a lot of money, but Mr. Lu has one. Recently, I heard that Zangjia has it, but there are no ten products in the north and south. The owner of the coin is Lu Laoji. "
In addition to the above-mentioned Er Quan, according to the data collected so far, there are more than ten works of DaSong collected in the world.
It is estimated that the market price of a piece is more than 40 thousand, but there are too many fakes.
