1990 baseball cards contain many different players including rookies and future hall of famers. The card makers from this year including Leaf, Topps, Donruss, Fleer, Score, and Upper Deck.

Leaf is the most expensive and valuable cards from this year, and they include the rookie baseball card selection of players that include Frank Thomas and Sammy Sosa.

In Donruss and Topps 1990 baseball cards, there are rookie cards of Bernie Williams and Larry Walker (also in Fleer) along with Juan Gonzalez, in addition to many other great hall of famers such as Cal Ripken Jr.

Presented here is a selection of 1990 Leaf baseball cards, which are the most valuable cards of this year's selection.  While some consider the Topps and Donruss baseball cards from this year to be overproduced and thus not worth that much, I think there is still significant value to be uncovered from these cards in future years.  In my opinion, these cards are undervalued. In 2016 I just recently purchased a cello box of 1990 Donruss baseball cards for a long term investment.
