Albert Pujols – 2001 Bowman Autographed
Baseball cards had become so ubiquitous by the early ‘00s that none was really considered rare unless they came with a gimmick. We are talking about memorabilia cards, autographs, and low-numbered parallel ones. Among the most valuable of these would be the Albert Pujols autograph card in the 2001 Bowman set. If you have this in good condition, you can get an amount in the four figures for it.

Don Mattingly – 1984 Donruss
Don Mattingly might not be in the Hall Of Fame, but his rookie Donruss card has up-to-date Hall Of Fame pricing. In mint condition, this card is worth up to $650. For a baseball player, who achieve quite as much as his steroid era counterparts this is quite a great accomplishment. According to Cardboard Connection, this one is tough to find. If you have it, you may want to hold onto it!
