I have been a longtime submitter to PSA but have decided to give SGC some (if not all) of my card grading business.

Since I have never submitted to SGC I was wondering specifically about the following 2 scenarios:

1. How will they handle an off center card when it comes to grading. PSA gives it the curse of death, the dreaded OC or MC.

2. If a vintage card is pristine in every way (sharp corners, great centering, etc) but it had the misfortune of being taped to someone's old photo album. What is the maximum it could grade? There is no paper loss on the card, the tape was carefully removed, but you can still see the residue it left behind.(and some slight discoloration where the card was never exposed to light)

Any help would be greatly appreciated.
