Thanks Comeaux. No way I am master in any coin. I am just a keen watcher here. Sorry I don't see any pictures here. Care to show me the link? Anyway Imperial coins refer to coin circulated after Qin Shi Huang (260 BC 210 BC) unified China to 1911. But really the only few coins I know a little bit are those from late Qing dynasty. Republic of China were formally established on 1-JAN-1912, hence we refer to coin circulated during 1912 to 1949 as Republic coins with the 1949 Sinkiang dollar being the last coin minted. People Republic of China were established on 1-OCT-1949.
