Hi everyone,
Previously at this site, I've found everything from a late 1600s coin to yesterday's surface covid coins.
The keepers are self-explanatory... but that little crudely ornate buckle is interesting. I don't think it's a knee buckle as the pin is oriented like a shoe buckle and the bend is too pronounced. Any ideas? Thanks and happy Memorial Day!
