I need someones help! I have a baseball signed by 9 players from 1950-1951 Philadelphia Athletics team. I can find all of the individual players, but nothing as a team. It’s signed by Bob Hooper, Elmer Valo, Pete Sauder, Eddie Joost( who later became manager), Alex Kellner(?), Bobby Shantz, Gus Zernial, Joe Tipton, and Sam Zoldak. Does anyone have any idea what this is worth?
