Hi guys,
Found a very corroded round thing in lake off Chicago. Started cleaning it just to make sure it wasn't trash and with the first big chunk removed it exposed a strong gold color. Turns out its what looks to be a naval button. It was a 2 piece, but the back rusted away. The front has a lot of the gilt left as seen in the photo below. It has the eagle on top of the anchor, which is above 3 cannon balls. Also has stars to the right and left, with what looks to be a rope border. Thanks in advance for any help!
