Who stamped my Babe?

What I wanted to know is what would happen to the grade because of the stamp. Ex: If it was a PSA 8, how many grades lower would it get because of the stamp?

In theory if the card is an 8 except for ONLY the backstamp shouldn't it grade an 8 (MK)?

Either a PSA 8(MK) or a PSA 6...I believe the standard rule of thumb is to knock the grade down by 2 because of the stamp.

MK is one of the qualifiers that they can choose to not remove,even if you select No Qualifiers. For Registry users, it counts as a 2 point loss on grades 3-9. For a PSA 2, it counts as a 1, and for a 1(MK), I think it counts as a 0.5.

Is that true? So a card that is otherwise a 9 but has a stamp on it could theoretically get a 7 grade? That seems pretty generous.

Yes, it would be a 9(MK) which would count as a 7 for set registry purposes, if it was Mint or Gem Mint otherwise. I cracked an SGC 20 out of the slab and I'll send it to PSA because it has a mark on it, and I think it would be a 6 or 7(MK). SGC is much harder than PSA on marks and miscuts because of PSA's use of qualifiers.
