Goober is in the process of cleaning out boxes from his basement and has found this:

BatDad dimly recalls getting a very young Goober a team-signed Brooklyn Dodgers ball (Hey, BatDad, what about me?? Only boys get team-autographed baseballs? Huh?--BG), and it seems to be from the '56 team, though we're not absolutely certain. The ball is inscribed "To Steve." The signatures: Sandy Amoros, Duke Snider, Pee Wee Reese, Carl Furillo, Rube Walker, Don Bessent, Walt Alston, Ransom Jackson, Gino Cimoli, Ken Lehman, Don Newcombe, Sal Maglie, Ralph Branca, Don Drysdale, Johnny Podres, Roy Campanella, Carl Erskine, Chico Fernandez, Ed Roebuck, Gil Hodges, Jim Gilliam, Roger Craig, Sandy Koufax, Charles Neal, and someone with a completely illegible signature.

Notably absent: Mr. Jackie Robinson. It's like Jackie doesn't care whether or not little Goober Jr. goes to college. Or else he didn't like Steve very much.

Thoughts? Can anyone help us on the year and the value?
