Off Center Reverse Grading Question

[Gr8Beldini]

Hi. Generally, what would the two major grading companies do with a card that a clear cut, razor sharp 8 with perfect centering on the front, but is very off center on the reverse? Would they knock it down a half grade? Full grade? Two full grades. Id like to get this card graded, but wonder if maybe I should just sell it raw. Any feedback is appreciated.

Well PSA lists their reverse centering grading criteria. The back of a PSA 9, for example, has to be at least 90/10 centering. So they are quite lenient compared to the front.

In practice, SGC and PSA care even less from what I can tell about back centering than their stated criteria. I've seen PSA even with cards miscut on the back still get a number grade.
