At the cowboy poetry gathering I talked to a buckle collector who told me that this Vintage Utah Territory American Express buckle was priced right but it was not original.
It was part of a scam. The guy made these buckles and sold them then he sold a book which authenticated them. He made more on the books than the buckles!
On the back side it has: American Express Co. recommend Kyanize brass polish. It has the words rare stones, a NTY inside of a chevron, Tiffany Broadway New York under the wire loop, the ad on the buckle back Kyanize brass polish and some other text we can't make out. It has a picture gallon tin can container, ..make sure you click on image to enlarge.
Great Patina, no defects, measures 2-3/4inches x 4-3/4 inches
