1991 Fleer Baseball Cards Most Valuable (PSA 10 Values)
The 1991 Fleer baseball set is best remembered for its blinding yellow borders—but within that polarizing design lies a surprisingly collectible core of stars, legends, and Hall of Famers. While the set was massively overproduced during the junk wax era, high-grade PSA 10 examples have emerged as sought-after gems for modern collectors.
Below, we break down the most valuable 1991 Fleer baseball cards based on recent PSA 10 sales and population reports. From generational icons like Ken Griffey Jr. to two-sport marvels like Bo Jackson, each card comes with a unique story that transcends its yellow frame.
1. Second Generation Stars (Ken Griffey Jr., Barry Bonds) #710
Estimated PSA 10 Value: $80–$120
PSA 10 Population: 217
Significance: This dual-player card features two of the most iconic sluggers of their era: Ken Griffey Jr., the kid with the sweetest swing in baseball history, and Barry Bonds, who would go on to become MLB’s all-time home run king. At the time, both were ascending stars—Griffey was establishing himself as a perennial All-Star and Gold Glove outfielder, while Bonds was already an MVP with elite power-speed numbers. The card captures the intersection of two Hall of Fame-caliber careers in their prime.
2. Nolan Ryan #302
Estimated PSA 10 Value: $80–$100
PSA 10 Population: 232
Significance: Even at age 44, Nolan Ryan was still blowing hitters away in 1991. The legendary right-hander had already thrown six no-hitters by this point (with his record-breaking seventh coming later that year). Ryan finished his career with 5,714 strikeouts, a mark that may never be broken. This card reflects the dominance of a pitcher whose longevity and velocity made him a mythical figure in MLB history.
3. Ken Griffey Jr. (Bat Around .300) #450
Estimated PSA 10 Value: $50–$60
PSA 10 Population: 74
Significance: This card is especially interesting because it has two distinct back variations that collectors chase. On the reverse, one version reads: “In 1990 Griffey Jr. would blossom and bat .300”, while the other says: “In 1990 Griffey Jr. would blossom and bat around .300.” The key difference is the word “around”—and the version with the word “around” is the more rare and desirable of the two. As for Griffey himself, by 1991 he was already turning into the superstar everyone predicted. Known for his effortless swing, highlight-reel defense, and charisma, he was the face of baseball throughout the ’90s. He finished his Hall of Fame career with 630 home runs, 10 Gold Gloves, and a legacy as one of the most beloved players in the game’s history.
4. Don Mattingly #673
Estimated PSA 10 Value: $50–$60
PSA 10 Population: 70
Significance: A fan favorite throughout the 1980s, Don Mattingly was the heart and soul of the Yankees before the dynasty years. He won the 1985 AL MVP, collected nine Gold Gloves, and batted over .300 in seven different seasons. Though injuries shortened his career, Mattingly remains one of the most beloved Yankees and a symbol of consistency and class at first base.
5. Ryne Sandberg #431
Estimated PSA 10 Value: $50–$60
PSA 10 Population: 46
Significance: A smooth-fielding second baseman with surprising power, Ryne Sandberg was the face of the Cubs during the late '80s and early '90s. The 1984 NL MVP was known for his professionalism, leadership, and offensive production at a traditionally defense-first position. He was inducted into the Hall of Fame in 2005 and remains one of the top second basemen of all time.
6. Jose Canseco #5
Estimated PSA 10 Value: $40–$60
PSA 10 Population: 19
Significance: In 1991, Jose Canseco was still riding high from his historic 40-40 season in 1988. As one of the Bash Brothers with Mark McGwire, Canseco helped redefine power hitting during the steroid era. While his legacy remains complicated, there's no denying his cultural impact on the sport during its most explosive offensive period.
7. Robin Yount #601
Estimated PSA 10 Value: $50
PSA 10 Population: 28
Significance: Robin Yount was a rare player who spent his entire 20-year career with one team—the Milwaukee Brewers. A two-time MVP, Yount collected over 3,000 hits and was known for his leadership, versatility, and humility. He entered the Hall of Fame in 1999 and remains one of the greatest all-around players of his era.
8. Roger Clemens #90
Estimated PSA 10 Value: $50
PSA 10 Population: 38
Significance: By 1991, Roger Clemens was already a two-time Cy Young Award winner and one of the most intimidating pitchers in baseball. Known as “The Rocket,” Clemens combined velocity, command, and intensity to become a seven-time Cy Young winner and 1986 AL MVP. Though his Hall of Fame case is clouded by PED allegations, his dominance on the mound was undeniable.
9. Orel Hershiser #208
Estimated PSA 10 Value: $45–$50
PSA 10 Population: 7
Significance: Orel Hershiser authored one of the most legendary pitching streaks in baseball history, tossing 59 consecutive scoreless innings in 1988—a record that still stands. That same year, he won the Cy Young Award, World Series MVP, and Sports Illustrated’s Sportsman of the Year. Known for his bulldog mentality, Hershiser was a staple of the Dodgers' rotation and later became a respected broadcaster.
10. Bo Jackson #561
Estimated PSA 10 Value: $40–$50
PSA 10 Population: 88
Significance: There’s never been an athlete quite like Bo Jackson. A two-sport star who excelled in both MLB and the NFL, Bo’s raw power and speed made him a human highlight reel. In baseball, he was an All-Star with 30+ homer power and a cannon for an arm. Injuries cut his career short, but his mythical status only grew—cementing him as one of the most electrifying athletes of all time.
