Collecting and selling are two different things. When I was a kid the Cubs did a charity basketball game across the street from my house, at town of 4000. After the game they signed autographs. I got Santo, Kessinger, Reuschal bros., and Billy Williams signed my glove. Those autographs are probably in a closet somewhere. So what did I do with my autographed glove. I used it to play baseball. We didn't think of possible value but it was cool a player signed something. Some famous people don't do autographs because it's about profit and not personal.
