Hi. For the vintage collectors here, what's your percentage difference in value for a card that is graded with the qualifier O/C versus with no qualifiers. I am looking at 1958 Topps for reference. So if card A is graded a PSA 7 and card B is a 7 O/C, how much would you take off? Any help in gauging this is greatly appreciated.
