There were 92 kinds of copper coins in Song Dynasty. In the Song Dynasty, there were "Chunhua Yuanbao", which was a pair of real calligraphy, and "Duiwen" and "Zhidao Yuanbao", which were a pair of real calligraphy and cursive script.
The coinage system was formed under the specific historical conditions of the Song Dynasty. With the rapid economic development in Song Dynasty, not only the number of coins increased greatly, but also the variety of coins was required to be diversified, which was also the need to stop the disadvantages of privately casting small money and the chaos in Qian Wen and establish the centralization of central currency. It is also the need to attach importance to literary works and carry forward the essence of calligraphy art in Song Dynasty. Therefore, the literary money born in the Song Dynasty is extremely precious, no matter its historical political value or artistic value in calligraphy. It has become a unique variety in the history of coins in China, and has been regarded as a precious coin by collectors in past dynasties.
In addition, the number of calligraphy in the past dynasties can be seen in the Song Dynasty. According to legend, there are four styles of Yuanfeng coins minted during Yuanfeng period in Song Shenzong, namely seal script, official script, regular script and cursive script. Among them, Su Dongpo's official script "Qian Wen" is calm and heroic, and is called "Dongpo Yuanfeng". During the reign of Song Zhezong, Sima Guang and Su Dongpo wrote Yuan Yu Bao Tong, a pair of calligraphy. Make the book currency popular in the Song Dynasty. The emperor who is good at calligraphy can't bear loneliness, and often shows his skill in Qian Wen. According to textual research, Song Taizong Zhao Huan was the first person who wrote "Imperial Calligraphy Money" by the emperor, and Song Huizong Evonne had the highest achievement in calligraphy among the emperors. He was incompetent in governing the country and keeping the country safe, and the "shame of Jingkang" was captured by nomadic people with his son Qinzong. However, I have a special liking for Qin Qin's chess and calligraphy, especially the calligraphy "thin gold body" iron painting silver hook, which is unique. The popularity of calligraphy coins in the Song Dynasty is not unrelated to the emperor's personal admiration, especially the popularity of royal calligraphy coins with year numbers. Qian Wen's style changed in the Ming Dynasty. Since the mid-Ming Dynasty, Qian Wen has been made by craftsmen, with plain fonts and neglected layout and structure, so it is impossible to talk about calligraphy.
