The 1990 Fleer baseball card set is considered one of the most valuable sets from the late 1980s and early 1990s. While there are no truly ultra-rare rookie cards in the set that can fetch tens of thousands of dollars, there are several cards that have appreciated well over the years and can be quite valuable in high grades.

One of the most coveted and valuable cards from the 1990 Fleer set is the Ken Griffey Jr. card. Griffey was already establishing himself as a superstar by 1990 and his Fleer rookie from 1989 was highly sought after. The 1990 Fleer Griffey card, while not technically a rookie, is still one of his earliest mainstream baseball cards. In near-mint to mint condition grades of PSA 8 to PSA 10, Griffey’s 1990 Fleer card can sell for $100-$300. Highly centered PSA 10 examples in flawless condition have even sold for over $500.

Another very valuable 1990 Fleer card is the Frank Thomas rookie. Thomas went on to have a Hall of Fame caliber career and his rookie cards from 1991 are expensive, but the 1990 Fleer is considered his true rookie by collectors. Like Griffey, the Thomas rookie appreciates significantly in high grades. A PSA 9 copy can bring $150-$250 while a PSA 10 Thomas rookie has sold for upwards of $600-700 due to its scarcity.

Staying with rookie cards, the 1990 Fleer Eric Davis rookie is also very valuable in top condition. Davis made a big splash early in his career and this is his most widely available rookie issue. Well-centered PSA 9’s sell within the $100-$200 range and pristine PSA 10 Davis rookies have sold for $400 or more. Other notable rookie cards that can reach $100+ in high grades include Tom Glavine, Moises Alou, and Gregg Jefferies.

Moving beyond rookies, superstar cards that pop in value include the Nolan Ryan and Roberto Alomar issues. Ryan is one of the most iconic players of all-time and his 1990 Fleer shows him with the Texas Rangers. Very nice copies in PSA 8-9 grade sell within the $50-100 range, but perfect PSA 10 examples have sold for over $250. Alomar had recently won a Gold Glove and was expected to be a star. PSA 9-10 copies of his 1990 Fleer card command $75-150.

Another star of the era with a valuable 1990 Fleer issue is Wade Boggs. By 1990, Boggs was a perennial batting champion and one of baseball’s best hitters. His 1990 Fleer is widely available but grades nicely. PSA 9 Boggs cards will sell within the $75-125 range while PSA 10s have sold for $200 or more. Mark McGwire also has a desirable 1990 Fleer card as he was breaking out as the new slugger for the Athletics. High graded versions in PSA 8-10 can reach $50-100.

While not as valuable overall as sets from the 1980s or star-studded rookie year issues of the early 90s, there is plenty of money to be made by acquiring and grading the top rookie and star cards from the 1990 Fleer set. Cards like Griffey, Thomas, Davis, Ryan, Boggs, and McGwire all have high end PSA 9-10 versions that can sell for well over $100 due to strong long term demand from collectors. For investors, the 1990 Fleer set remains an often overlooked gem full of cards that offer breakout potential with a top grade.
