on the Cronin, I think SGC just messed up and printed the wrong flip. They have the #63 Proof noted because they have graded them before...

I would call this Cronin in link above and also the Joe Judge missing ink, both printers scraps, and not true proofs.
The real R319 proofs are far different, they will have design or card number changes, ie #106 Durocher wrong number, #110 Goslin name on 2 lines, #123 Russell dark cap, #123 Sewell wrong number, etc.
