Just about every experience sport card collector and dealer know the antics of PRO Grading.  I have seen about 40 cards graded by them and all of them were trimmed.  About two years ago I bought a card from a dealer (PRO graded).  When I got it I found it was trimmed and not a very good job at that.  This 1965 Mantle instead of being worth a few hundred dollars was worth almost nothing.  I asked for a refund, but the fine print stated "No returns on graded card".  note: if you see this in an auction - bad sign.

I did some of my own eBay/CSI research and found this dealer was not only selling PRO graded cards, but he was also buying vintage cards ungraded and generally in fair condition.  I started a log of cards bought and cards sold.  I even copied some of the photos of the cards.  I remember he bought a 1959 Al Kaline, not what I would consider a big collector item.  Three weeks later he had it on ebay, but now it was graded PRO-9.  His price for the card was $3.50, he sold it as a mint condition card for $82.00.  Not only were there many cards but I started to compare the photos of what he bought and what he sold.  I noted several cards with print flaws, marks, back to front relationship and other areas that would make a DNA expert pay attention.  These were the same cards.  For one month I added he made $20,000 in gross profit.  I also found out he had another buddy who was doing the same thing.  When I complained to him about this action he changed his feedback to private and also his bidder list was changed to private also.  This prevented me from doing more research.  I also gave this information to eBay, but I guess they are not cops and figure buyer beware.

Guess what they are still selling on eBay.......find them, it isn't hard.
