Hey all, thanks in advance for any helpful feedback. I have recently purchased a 1953 Topps Mickey Mantle PSA 7 oc. (Thanks to fellow board member Pete Sycks). Anyway, I want to get rid of the oc qualifier. I wanted to send it back to PSA to try and get it re-graded as a PSA 7. Or even maybe a 6.5. Does anyone know if I can send just that one card back or is there a minimum. Does anyone have any experience with this or helpful hints?
