Recently found these 3 items. The smallest is a button, 3/4". The medium seems like a button with the shank broken off, 1 3/8". The largest I'm not really sure about. It is really large, 1 7/8". It looks like on the back there were 2 possible shanks that broke off and then the holes were punched threw after. On the front there is a light design around the edge. They were all found within 10 feet of each other. Any help identifying and aging would be appreciated.
