Went digging today at a brick house built in the 1820's and found some cool relics! Got two flat buttons, one that looks like it was stepped on by a horse or something since it's so flattened out, and the other which is probably my most ornate flat button! The only thing is...where are the older coins? Anyways does anyone have any idea what the possible button is on the very top? It's empty in it and with no sign of a shank mark so maybe it's the front of a two piece button? Plus any clue how old it is or what the design represents? Thanks!
