American Dollar Dog

The caption on the back of this photo, according to the web site where I found it, says:

A cabinet card by G.W. Brown from Cheyenne, Wyoming circa 1900. Text on the back reads: “TONY, The American Dollar Dog,” is probably the only dog in the world that can tell the difference between an American dollar and a counterfeit or Mexican dollar. However incredible this may seem to many, it is nevertheless true and there has never been counterfeit dollar given him to test that he failed to detect. Any one doubting the above statement can be convinced by calling at the Jewelry Store of Geo. W. Brown, 17th st. Cheyenne, Wyo.”
