Up for bid is a beautiful enamel double gold filled pin found at a local estate sale. From what I could find this is a fraternal pin, a service cross pin. The back side has some writing in Polish and also marked with the gold content: 1/10 10K Double G.F. and also what looks like an N in circle mark, maybe the maker. The pin measures a hair under 1 1/2 inch wide across the eagle wings by 1 13/16 inch tall. The eagle has a different gold color and is not marked, so I am not sure if this is gold filled or not. See all photos as part of the description.
