Submitted these recently through my local GameStop. I did 5-6 orders last year through them and didn't have any issues. Overall has been a decent experience and has yeilded good returns (with the exception of the Spider-Man acetate card but that one is really on me).
For my fancy or higher value items, I submit directly to PSA myself.
Does anyone else submit to PSA through GameStop or another intermediary, or do you submit directly to PSA?
I am also contemplating submitting to SGC this year. I have a stack of vintage cards I'd like to grade.
I will be making submissions routinely and sharing the results. I'd be interested to hear any opinions and answer any questions.
Some stuff I grade for value or to make money and some stuff I grade for fun for my own collection. I'd love to hear from others and their experience with the grading process!
