I got these 3 at an auction. I'm not sure about the authenticity. I bid on them knowing they could be fake. No harm in trying. :) P1010176.JPGP1010179.JPGP1010182.JPG
Welcome, but I don't quite understand your logic. Why buy if it may be a forgery? It just enriches the bad guys. Feel free to post pics here before you buy. The S in Sandy Koufax looks off.
The Mickey Mantle is a forgery in my opinion as well as the Koufax. I do not study Muhammad Ali's signature enough to opine, but from the few I've seen, it looks off. I would get a refund for these pieces if I were you. Next time, you should come here and post a picture asking for an opinion before you purchase; there are many nice people that would love to help.
Hold on before judging. I purchased a trunk with a lot of different items in it. I knew that the pics where in the trunk and I really wanted the trunk. I should have explained better.
