Most likely this medal was created on April 9, 1913 in four classes. At least according to the only (?) published source about this decoration – “Orden aus aller Welt Sammlung Tammann 80. Auktion Katalog, 4-5 November 2008, p.178”. In turn compilers of this catalogue used “The China Year Book, Chicago 1916”, “The China Year Book, Chicago 1920” and “Who’s Who in China, 3rd edition, Shanghai, 1925”. Since this medal wasn’t listed in “The China Year Book of 1920” they concluded that: “It seems that it was distributed after that year by only Sun Yat-sen’s Government in Canton. The maker’s name and the date are indeed typical for decorations by the Canton Government”. There, that’s all we have.
Now let’s take a look at different classes and variations of this interesting medal. Since we don’t have any precise information about design of different classes of this medal I think it will be a good idea to avoid naïve (and possibly incorrect) labeling. That’s why instead of class I will use the word variation.
