How much does an authentication sticker impact a grade?
I see a comic at auction that is CGC slabbed with an 8.0, with these comments:
sticker left bottom of back cover
crunch right top of front cover
crease bottom of back cover
spine stress lines spine
It’s a signed issue and there is a Beckett auto authentication sticker on the back.
Is there a standard deduction or grade max for a book with a sticker on it?
I’m wondering how much it can be improved with just removing the sticker
Thanks!
