Gee, I looked and looked and looked and couldn't find that dang 5% tin & zinc anywhere. ~ Chris
Let you know when I have it looked at. Thanks all
Composition .950 copper, .050 tin and zinc.
That does not make them annealed.
Even though the pics are poor (my pics are bad too ) it looks like the material is raised above the surface of the coin. It also appears that their is some sort of residue around the perimeter. Looks a lot like residue on the reverse, as @paddyman98 said earlier.
It's highly unlikely that the zinc and/or tin would remain segregated in the melt especially with no other evidence of improper alloying.
Objectively look at the coin to determine if this stuff on the rev is raised. If it is, it wasn't there before minting. You can also Try soaking it in acetone (not nail polish remover) and see if the residue dissolves
How long should I leave the coin in acetone?
