You are bidding on a cool and very hard to find, circa 1890s to 1920, hard to pinpoint, silver tone metal, unknown content, Tuebor marked front with eagle type symbol as shown, some kind of US Army veterans affiliation I believe, button back lapel pin in the picture. 5/8 inches wide. Nice shape, some light wear throughout, could use a fine cleaning. Zoom in for details.

Look at the picture.
