Pop report on an SGC 8 is only 6 total with none higher with 40 graded total.
I would NEVER send a card to SGC in a PSA holder. That being said you have a conundrum here.
It is honestly a very nice looking card and most likely could have gotten a straight PSA 8. That OC in this case is certainly borderline.
You could send it back to PSA and ask for no qualifier but why?
It's a MINT 9. I feel the OC is a bit BS to be honest.
SGC would grade this a 6 to an 8 and most likely a 7 but it might be worth the risk if you need an 8.
If this were my card, I'd be proud to own it. You have a good eye.
I'd probably break it out and get an honest grade from SGC.
It would look a heck of a lot better even in a 6 or a 7 SGC holder.
My opinion only. Please keep us posted.
PS I love "shaggy" edges and usually factory fresh shaggy edges help a card that has never been tampered with. This card BELONGS in an SGC holder.
