The coin was cut straight down the middle and a 45° angle on the cut, looked like it was an intentional cut. I checked around that spot pretty good but didn't find the other half, probably got cut in half back in the 1800's. That button I found yesterday looks to be an early civil war Revenue Cutter Service coat button. Later on after the civil war they became The Coast Guard, pretty excited about that one, I think that one might be kind of a rare find. The shank is still on the back of it and its not dented or scratched up, and it whole, I got some of it cleaned enough to see some gold gilt on it and once I'm able to clean the rest of the crud off it, it will be a nice looking button, the flat button from yesterday was made in London.
