Hi Everyone, I bought a small box of military & Police buttons. They were all old and backmarked. I have one though, that I would like some help in identifying. I found some buttons on this site that looked similar but were excavated, said to be Confederate, and backmarked. So, I’m not getting excited about this one but still curious. It is silver in color, the block “I” on the front, no markings, pretty clean, not perfectly rounded, has some flat spots around the edge, the back looks like a drilled hole shank possibly soldered on. it measures 7/8”, is hefty, and not magnetic. Thanks, Cheryl
