Super cards Leon.
I'm sure that you know that I love 'em both! If the timing was right and I happened to have the funds - I'd be in the 15k ballpark for the scrap and 25k ballpark for the proof.
I'm certain that I'm not alone in terms of a desire to have cards like these --- so my guess at today's hammer price in a top tier auction for the pair is 50-70k.
Best,
Scott
P.S. If you ever do want to sell 'em shoot me a line
