Signed baseball (a league of their own) real players.

following the release of a league of their own, I met the original players, dotty pepper and all. I have 5 or 6 signatures, with years they played, and years they were inducted in the hof. Many have since past away. Am looking to get an idea on value, and a possible trade for a Jim Croce autographed portrait, or maybe some old u.s. Silver coins. Also have a Nolan Ryan signed baseball I'm willing to trade. Open to all offers.
