Anyone with enough numismatic background to understand the resulting piece would be far less likely to be scrutinized as a counterfeit, while still retaining huge profit potential. Damaging/wearing surfaces to hide evidence of counterfeiting is a time-worn practice.
I think it's great that he shared his coin with the rest of us here. I know myself and others are going to learn a thing or two about this type of coin and is it genuine or a well done fake.
The evidence is insufficient either way in these images. I believe the preponderance of evidence indicates it's real but impaired - always liked low-grade Barbers and this is precisely how they wear, and (to my mind) difficult to fake this well. If you learn anything from it, learn to take an out-of-the-blue post of a rarity like this and use it to train the reflex to immediately check date and mint mark location and orientation, and any other issue-specific markers. None are visible here for this coin, so all you have left is speculation. The corollary to "question everything" is "then go look for answers to the questions."
From what I can tell from these images - the coin appears genuine - It has Reverse A - MM is above "R & D". The die markers for the OBV are worn away, however based on the low quality images ( they are better than I can do, so don't feel bad ) I would say the spacing of the second One is correct. The MM is the correct shape and size...placement is good. The coin should be graded AG 3 details - net Poor. It's value is what the market will bear - I wouldn't pay more than $500 for it, personally. Then again, I wouldn't pay anything for it, as it doesn't fit in my collection.
