who is going to turn in their card for overgrading, unless they bought it for the higher price/grade and didnt think the card deserved the higher grade and would rather have the lower grade adn the cash difference?
but its still in the higher grade holder for when THEY sell it, so what's the difference? i don't see someone sending a card to sgc complaining it has too high a grade.

The SGC Guarantee
SGC Guarantees that all cards submitted shall be graded by SGC grading experts in accordance with SGC grading procedures. In the event the owner of an SGC card believes that the card has been overgraded with respect to such procedures, the owner may resubmit the card to SGC for a review of the assigned grade.
If the grade determined under such review is lower than that originally assigned to the card, SGC shall, at SGC's discretion, either replace the card or pay the difference between the current fair market value of the card at the newly established grade and the current fair market value of the grade originally assigned to such card, in the form of either cash or grading credit. Due to the volatile nature of the sportscard market and Internet auctions/sales, the selling prices in these auctions do not necessarily represent the current fair market value of any particular sportscard. SGC will determine the current fair market value of a card which is assigned a lower grade on review, based upon what SGC believes to be reliable current market information. Clerical errors with respect to the description or grade of the card(s) which would be obvious upon inspection shall not be subject to the SGC guarantee stated herein.
