I collect autographs because these guys are my heroes(other than my dad). I watch these guys do something millions of people dream of doing but can't because they aren't good enough. I don't really care about value too much, I'm not selling anything. I do know that if I can get my packers helmet signed by Favre it will be worth a lot. Its hard to really explain, I'm sure someone else could do it better than me. The reason why people need multiple autographs of a certain player is because we have multiple items we would like signed by them. There is a team bat, team ball, 8x10s, bobblehead, magazines etc... Its no different than any other hobby really. I don't understand collecting stamps, but people do it.
