What’s an acceptable grade for vintage cards?

[Exhibitman]

I want them to look like they did when i was a kid: no better than ex on most older cards and the Mantles all p-vg as they were when I pulled them out of bargain boxes. The cards from when I was a kid in the 1970s have to be pack-fresh: For every seven cards there has to be one centered, clean, crisp card, and the rest off-centered (every Nolan Ryan I ever pulled from 1973-1979), miscut, print-flawed (e.g., 1976 Topps George 'Snow Day' Brett), and every seventh card wax-stained or gum-stained (preferably the Mike Schmidt cards, which always seemed to be the case when I was a kid; is there a 1975 wax pack Schmidt that doesn't have a stain, 'cause all of mine had stains?). If I owned a 1976 Schmidt that was centered or a Jackson without that print flaw in the color band it would just feel wrong.
