JimB"I know that if I buy an sgc 60, it wont have a crease or wrinkle for example. I cant say that with psa - and in fact, have had too many psa 5s fail to cross because of a difficult to detect wrinkle. "
I submitted a '53 Topps Campenella to PSA about ten years ago. I was sure it would come back as an 8. It came back a 6. I broke it out and resubmitted it at a show. It came back a 6 again. I questioned them at the show about it and the guy brought it back to the grader. He circled an area on the back of the card that he claimed had a minor wrinkle. I could not see it under a 10x loupe. Regardless, they said that a card could not grade higher than a 6 with a wrinkle. I imagine it would have to be pretty minor and the card to be otherwise nm/mt or mint to receive a 6. This "wrinkle" was so minor, it is impreceptible under 10x loupe. Assuming their grading standards have not officially changed, that is their policy. It differs from SGC's. SGC is much more tolerant of centering at the vg level. I have seen at least a half dozen example of 0/100 centering or worse at the SGC 40 level. THey each have their nuances.
