The 1991 Upper Deck baseball card set was truly revolutionary and is considered one of the most iconic and valuable sets of all time. Upper Deck broke into the baseball card industry in 1989 and completely changed the game with its unprecedented quality, attention to detail, and focus on the collector experience. By 1991, they had solidified themselves as the premier brand and their second flagship set took the hobby to new heights.
Some key things that made the 1991 Upper Deck cards so special and desirable included the thin glossy stock they were printed on, sharp colorful photography, and premium feel in the hand. Upper Deck also pioneered modern security features like holograms, 3D embossing, and microprinting that made their cards very difficult to counterfeit. Perhaps most importantly, they had exclusive licenses with MLB, the MLBPA, and the players’ union which meant they could use players’ names and likenesses.
While there are many highly sought after rookie and star cards from the set, here are some of the most notable:
Ken Griffey Jr.: Widely considered the crown jewel of the set, Griffey’s rookie card showcases him in glorious action photography swinging the bat. Its rarity, Griffey’s iconic status, and the card’s pristine condition and visual appeal have all contributed to it regularly selling for well over $10,000 in gem mint.
Frank Thomas: Another star rookie, “The Big Hurt” looks determined in his portrait shot. Thomas went on to have a Hall of Fame career and his card remains a top chase for White Sox collectors. Near mint copies trade hands for $3,000-5,000.
Nolan Ryan: Iconic photo of the flamethrower winding up is paired with his then-record 5,000th career strikeout milestone on the back. Even in well-worn condition “The Ryan Express” card commands $500-800 due to his legend status.
Cal Ripken Jr.: Clean and classic full body action shot highlighting Ripken’s smooth defensive skills. As the iron man and one of the most respected players of all time, his card remains a steady $300-500 even after all these years.
Kirby Puckett and Dave Winfield: Both all-time great outfielders are captured in beautiful action photography on their ’91 UD cards. In top grades their cards can reach $1,000+ due to their championships and Hall of Fame careers.
Don Mattingly: Clean cut portrait of the ’85 MVP shows why he was one of the most popular players of the late 80s. High grade “Donnie Baseball” cards trade between $500-800.
Mark McGwire: Powerful full body image foreshadows “Big Mac’s” record breaking home run chase later in the decade. His rookie card in gem mint can reach $800-1,000 for dedicated collectors.
While stars on winning teams like the Braves, Blue Jays and Twins are most coveted, there are also some more obscure gems to be found:
Darren Daulton: Iconic action shot of the heart and soul Phillie blocking the plate. In sharp condition it can reach $300-500 due to sentimental Philly collectors.
Bret Saberhagen: Close up portrait of the ’85 Cy Young winner. Near mint copies can be found for under $100 but demand may increase as Royals contenders gain new fans.
Jeff Bagwell: Clean image highlights Bagwell’s smooth swing during his early Astros days. High grade copies trade in the $150-250 range with room to appreciate as his Hall of Fame case strengthens.
Chuck Knoblauch: Action photo captures his speed and skills. Twins collectors have pushed near mint examples up to $150-200 in recent years.
Omar Vizquel: Full body shot shows smooth defender’s range. Very tough to find in high grade but could gain more collector interest as one of game’s best fielders.
While players like Clemens, Bonds, and A-Rod may be more controversial today, their ’91 UD rookies remain some of the most visually striking and dynamically captured rookie cards ever. For dedicated collectors, finding high quality examples of any of these stars from the 1991 Upper Deck set is a true thrill and crowning achievement. Over 30 years later, it remains one of the most beloved releases that still has the power to excite hobbyists of all ages.
