$50. 792 cards in Binder.There are two main standouts about the 1984 Topps set: The Don Mattingly rookie card and the team names in huge block letters that run down the sides of the cards. Mattingly may not be a Hall of Famer, but he's a hobby icon and that card remains high on many collectors' want lists. And those block letter team names combined with the dual imagery on the front make this set's design truly unique. Cards are Nr Mint.
