Here is a ca. 1900-1920 coin (800/1000) silver pin, unmarked, that features a lovely, bezel-set, Colorado turquoise cabochon stone measuring 3/4" X 3/8" X 3/16" thick. The pin measures 1" X 1 1/2" wide and weighs .27 oz. There are traditional Navaho designs on the silver, indicating a Navaho maker. The pin was probably designed by Fred Harvey, the hotel magnate, and sold in one of his hotel's gift shops. The design is simplistic; the pin is early. (There is a C-catch rather than a modern safety catch, indicating age.) This one is a collector's item.
