The pin is unmarked and tests positive for sterling silver. The surface has aged mellow patina/ tarnish both front and back which attests to its age.Beautiful old feel to the sterling silver. The closure includes a C clasp and long pin stem with some slight bends to it. A very nice Old Fred Harvey bar pin to add to your early handmade Navajo or Fred Harvey Era pin collection. Measures: 2 3/4" long; 5/8" wide.
