The most valuable thing I own would have to be my Hank Aaron and Willy Mays signed baseball. Along with half the Atlantic Braves baseball team. Its been passed down a generation and I cannot wait to pass it down to my kids. Its so awesome having a piece of history.
What do you have thats most valuable to you? and why?
Sorry to break it to you, but those mass 'team signed' balls aren't actually signed by the player.
