The first picture is the item.
Two inches wide, round shaped, brass object.
It has an eagle clutching a ship anchor and a cannon.
6 cannon balls stacked in a pyramid shape underneath eagle.
The second picture is of the back. It is thin brass material about thickness of old metal soda can.
The below items found at same dig site. Need help identifying.
I think other round object may be smashed bullet with holes punched in it. It also has lines scratched on it, possible home made necklace. Other two items brass.
