The picture shows the Zhongwai Tongbao Guanping Yin Yiliang silver coin. It was born in the late Qing Dynasty. There are different opinions about its casting background. Some people believe that it was cast in Hong Kong by the British government in order to control trade with China during the Xianfeng period; some people say that it was a sample coin cast by the Shanghai Jiang Customs when preparing for tariff reform. The words "Guanping Yin Yiliang" are in the center of the front of the silver coin, and "Zhongwai Tongbao" is surrounded by the outer circle. Due to the scarcity of the existing number and the controversial background, it has attracted widespread attention in the collection market and has high collection value and research value.
