Tacc Pillar of the Community United States 3535 Posts	Posted 12/20/2024 4:26 pm In my opinion your coin looks to be an example of "Flat Field Doubling" I did include a link if interested. https://www.error-ref.com/?s=Flat+field+doubling Report this Post to the Staff

It's unique to proofs, and it refers to, proofs being struck 2-3 times during the minting process and quite often causes very slight doubling, especially when highly magnified, like we see oh so often.
