You could see about an informal review. I'm not sure PSA would do it.
I brought a couple cards to a show that I thought SGC had gotten wrong. Both T206s. One was a 50 the other a 40. The 50 looks great the 40 looks a bit better than 40, maybe a 50 maybe a bit better or worse depending. I dropped off a few cards for grading and asked if I could get some info about the grades on a couple other cards. The guy gave a quick look and showed me why.
The 50 has a
tiny crease about halfway up the left edge. And a flake of paperloss on one corner that's less than the wear on some 50's I knew about the tiny flake of surface missing but not the tiny crease. Combined they kept it to a 50.
The 40 had a very light erasure on the back that I hadn't seen. And I'd had the card since the early 80's.
He also mentioned that I could have them reviewed, but that they probably wouldn't change. I agreed that now I saw the flaws the grades were right, or at least so close as to not matter.
Can't hurt to ask, the worst they can say is that they won't look at them without being paid.
