Sammy Sosa has, I think, 11 rookie cards. His 1990 Leaf is easily the best one of the bunch. There was a while there where it was booking for roughly $100. This card was very popular. And very expensive. But now…not so much. PEDs will do that, I guess.
Still, its a nice card from a set that is still kind of popular, if not historic. 1990 Leaf was one of the hobbies first premium sets, and collectors loved it. It also had a very good checklist. Key rookie cards in the set in include Sosa, Frank Thomas (#300), Larry Walker (#325), John Olerud (#237), Dave Justice (#297) and Albert Belle (#180).
