That's a great collection. Best ones are the stars: Musial, Yogi, Jackie Robinson, Campanella, Ted Williams. All look real to me, for starters. There are some of these that are counterfeited, but their print quality is different, they're zoomed in, and they have white or gray backs. Yours should all have cream backs. There are also some image variations that may be uncommon or rare, so just because it's a common player doesn't mean it wouldn't have demand.
In those conditions, they vary from about $2-5 for the commons and $20-250 for the Hall of Famers and stars. Too bad the Yankees team isn't from 1951, since then it would have Mantle during his rookie season. You can see many of them posted for sale on COMC.
