13 stars and a bust of a younger George Washington
prior to being president...
The two tabs on back press fit into something to hold it in place.
I am wondering if the "curve" is by design or was it bent while lost in the ground, is it meant to be flat?
Appears to be machine stamped brass or is it plated steel, hard to tell from the picture?
Very thin metal, not strong and not much corrosion?
