Hello, my name is Clint and I am new on the board. I used to collect cards as a kid and am starting to get back into it a little bit on a limited budget conscious basis. As you probably guessed from my name I am a Cubs fan and I am currently looking to acquire a topps ernie banks card in psa 6 or better from 1954-1971. I have been in contact with a guy who has all the remaining banks cards that I need, all in psa 6. The prices he has quoted are similar to what you would expect to pay on ebay. Looking closely at the 1969 card there appears to be a large dark blob of dirt or something near ernie's shoulder. When I brought this up he offered to replace it with a different 1969 banks psa 6. Also the 1961 seems to have odd kinda blotchy print defects around the border. My first question is how could the 1969 card end up in a psa 6 holder? My next question is whether it could be possible that any or all of these cards are fakes? Seems unlikely to me as I would think someone making phonies wouldn't waste their time with psa 6 ernie banks cards. Anyway I have included scans he sent me of the cards below, any opinions/advice would be greatly appreciated.
