JayExtending the reasoning I am hearing from some people in this thread, all blank backed M101-4/5s would be proofs. That is obviously not the case. Don't know who the dealer who sold the piece was, but unless he/she has further information I would say that they were wrong(amazing how most dealers err in their favor). I agree with Barry and Corey that, short of finding some new evidence, this piece should not be considered a proof.
