I am a native Chinese scholar and expert on historic machine-made silver dollar minted and circulating in old China during the Qing Dynastry and Republic of China until 1949, as well as foreign trade dollars from the USA, Japan, France, Mexico, etc, circulating in old China in the same period. I would like to display my collection of old silver dollars and expose the counterfeits by US coin dealer interest groups and their member coin grading companies such as ANACS, PCGS and NGC.
