Is there any way to tell why a card graded by PSA gets the grade it gets? At least with Beckett and there sub grades you have some idea.
Not as far as I know. Would be nice, though.
Who knows, I have a "PSA 10" that has visible damage on one of the corners - then I have PSA 6 and 7 vintage cards that look almost perfect.
Thats why I prefer Beckett with their sub grades
