If you want to maximize value I'd suggest submitting them to PSA/DNA when the run a $10 special (maybe it's $15 now).
For whatever reason, people will pay 5x more for these autographs when they are encased in PSA/DNA plastic.
Some of them may not pass, though. I think at least two of the Koufax may be ghost signed, and Goslin, Combs, Faber, and Ruffing all had their wives signing for them after illnesses and strokes. Others on this board will know if these are good or not. The Goslin looks exactly like one I had denied by PSA.
PS. Make sure you get a "good" Combs.
