Guangxu Yuanbao was one of the currencies circulated during the period of Guangxu in Qing Dynasty. Zhang Zhidong, governor of Guangdong and Guangdong provinces in Hubei, took the lead in introducing British coin machines to mint silver and copper yuan, which were followed by other provinces. There are nineteen provincial bureaus casting. Except for the central household department, the copper coins cast by local provinces are all inscribed on the upper margin of their fronts. Guangxu Yuanbao is the first large denomination currency circulated in Guangxu year of the Great Qing Dynasty. It is the first circulation currency to introduce overseas technology in China. It also has certain historical significance for today. Among Guangxu Yuanbao, the most valuable is the Shuanglongshou coin made in Guangdong Province: Kupingzhong one or two. Dragon is the symbol of power, nobility and honor in Chinese traditional culture. Among the collections, the collection of dragons is the most abundant and has great appreciation space. Therefore, it has become the law of the collection circle that every Dragon must hide and every Dragon must rise. Especially the porcelain and silver coins, which are marked by the image of the dragon, have only risen for many years, and the shuanglongshou coin is one of the outstanding ones with high value.
