Autograph baseball, old mags question

Hi everyone:
I'm new to the board so I wanted to introduce myself. My name is Steve and I'm selling off my card and memorabilia collection that I built with my dad during the 80s.
I have a bunch of autographed balls that I'd like to sell: Sandy Koufax, Tom Seaver, Whitey Ford, Don Sutton, Dave Winfield, Lou Brock, and Eddie Matthews. I know they're legit - I saw them at card shows - but I realize I need to authenticate them. Are they worth it to sell? Besides Koufax, it seems the PSA/DNA cost would be more than they would garner.
Also, I have some Street & Smith baseball preview magazines from 1950, 1953, and 1962. They're in goode condition. Any market for these?
Any help would be appreciated. Thanks!
Steve
