Kaiyuan Tongbao is the currency of Kaiyuan Tongbao in the Tang Dynasty, and the coin has "Tongbao" in the Tang Dynasty. In the early Tang Dynasty, the five baht of Sui Dynasty was used, which was light and confusing. In the fourth year of Wude reign of emperor Gaozu of Tang Dynasty (621 A.D.), in order to rectify the chaotic currency system, the Sui coins were abolished, and the strict standard of the five baht in the Western Han Dynasty was imitated, and the "Kaiyuan Tongbao" was created to replace the remaining five baht in the society.
This coin is treasured by Mr. He in Shanghai and is a rare and excellent collection.
Kaiyuan Tongbao is thick and moistening. It has no dryness and astringency of the new forgeries. Further investigation of the texture of the coating shows that it is a pure, natural and practical one, and a little green rust is also found. Some rust is distributed in different depths on the whole, showing a natural appearance, which shows the unique appearance of rust slurry handed down from the Qing Dynasty. In addition, looking at the material, we can see that the white copper is bright, the copper quality is superior, and the copper color shows the aging. In a word, those who know a little about the ancient spring and its good nature can clap their hands and say that the gate is open.
The original "Kaiyuan Tongbao" was inscribed by the calligrapher Ouyang Xun. The shape of the coin is still the same as that of the Kong Yuan coin of the Qin Dynasty. It is stipulated that every ten Wen should be weighed one or two, and the weight of each article is called one coin, while the weight of a thousand Wen is six catties and four Liang. From then on, China's currency system officially broke away from the two systems of baht in the name of weight and developed into Tongbao currency system, which became the standard of coinage in all dynasties after the Tang Dynasty, which lasted for nearly 1300 years.
Kaiyuan money is not the year name money (Kaiyuan is the year title of the Tang Xuanzong period), but has the meaning of opening up a new era, correcting the accumulated defects of the past currency system. Later facts have proved that Kaiyuan money has indeed ushered in a new era, which marks that wuzhu coin, which has been dominant for six or seven hundred years, has finally bid farewell to the circulation field. From the Tang Dynasty on, coins were no longer named after weight, but renamed as Tongbao, Yuanbao or chongbao, and were given the year title at that time. This kind of currency system lasted until the end of Qing Dynasty.
