I agree with Marc...the value is in the memoriabilia, not the cardboard. A grade of "Mint" by a grading company isn't going to affect the value of the card that much imo cause it's the cardboard that's being graded, not the authentication of the memoriabilia. You have the certification by the Card company and that is your "authentication." I would leave it as is.|
BTW: Congrats on getting the card!
Always looking for GAI,SGC,PSA vintage Hockey and Boxing.
