Probably get more attention over in the "Postwar Baseball Cards Forum (Pre-1980)" forum... anyway, the gray backs are supposed to be slightly rarer though only occasionally is someone expecting a premium for them. When someone is looking for a premium they might want 10-20% for commons and maybe 25% for stars. This is unusual though - typically folks don't differentiate - and, to the best of my knowledge, most don't bother collecting both stock variations.
