HiYa's from a newcomer. So I received this 2007 John Adams Presidential Dollar a couple years ago. I bought some double edged, and missing edge letter coins, and this one was included with a purchase. The back of the coin with the Statue of Liberty is fairly legible and centered though lightly struck. Poor John, on the coins face, has no recognizable features, but his name and some lettering are present. The edge lettering is distinguishable but distorted. I'm pretty sure this damage occurred at the mint, but I haven't found other examples of this type of stamping error. Any information or insights would be appreciated. I apologize for the pics, tough to balance light/glare trying to show detail. Thanks Ken
Welcome to CT. I'm thinking the damage happened after it was struck. No sure way to know what caused the damage.
Post Strike Damage (PSD) You can tell because there are still details visible in the areas that have been hit and flattened. That means that the coin was struck normally and then the impacts and damage came later. Even if these impacts occurred while it was still inside the Mint (and there is no way to prove where the coin was when the damage happened.) it still happened after the coin was struck so it is PSD not a mint error.
IDK, but why would one side be normal, since both sides are struck at the same time? That's why I would guess it was damage and not a mint error. If something happened at the mint to do that, I don't see how the reverse would be unaffected.
