My mother in law bought a few proof sets and I was checking out this 1964 proof set and noticed it appears that the coins sealed within it are damaged. Now my eyes are not the best and I see the disclaimer from the Philadelphia Mint stating that any “damaged” coins must be a figment of my imagination. Or do I not fully understand what a proof set truly is? I was under the impression that these are all virgin untouched coins in a state of perfection. So set me straight or cry alongside of me. Should they be unblemished? Am I imagining the scratches that I think I see on these coins?
