My Asia library is quite good. The mint mark doesn't match any of the marks in my Chinese references. I am indeed hoping someone out there can help me puzzle it out. This is an excellent forum for getting and giving info. Numismatics is a very solitary hobby. The only time we get together are at club meetings, local, regional, and national shows and conventions. The internet has given so many more people access to other collectors, incredible research material, and exposure to new interests. This really is a great era in the numismatic community.
