The 1990 Fleer Baseball set is often remembered for its clean design, massive checklist, and key appearances from some of the most iconic players of the era. While the majority of the cards from this overproduced era hold little monetary value, there are several standout cards that command solid premiums in PSA 10 condition due to iconic player status and rookie-year relevance.
