Yes these cards look very suspicious, the definition is weak and the background colors don't look right to me. I wouldn't take a chance, especially with the as is final sale inscription.
This guy is a real dirt bag! He even put minor dings on the corners to make them look more authentic. And the lame story about the estate sale is classic scam artist.
I agree with Jim's comment about c56 and c55 reprints being put all over eBay!
You used to be able to see who was bidding on a card and you could warn them when they were about to buy a fake, but not anymore!
