I'll tell ya, I once pulled a blank back Oscar Gamble from a grocery store pack and I've had blank back proofs that came straight from the Topps archives. If I didn't know the provenance of the cards, there would be no way for me to tell which one was a proof and which one was a blank back error. There are times when a card is obviously a proof (the T206s with the little crosses, or one color progression proofs on mylar). But in many cases there's no practical way to tell, so one shouldn't loose sleep over the issue. |
