20. Barry, Jack (Print Group 2)
Jack Barry has even fewer total Sweet Caps than Barger right before him, but his Factory 25 is not as rare. Interestingly, using the 29 graded PSAs with factory numbers, the Factory 25 looks more common (24%), but in my survey of 31 PSA slabs, only 16% were Factory 25s. I found only 6 SGC graded slabs, and 2 of the 6 were Factory 25s.
