The 1991 baseball card season featured some very valuable rookie cards and inserts that have increased significantly in value over the past 30 years. Some of the top cards from 1991 that are worth chasing for collectors and could fetch a good price if in top condition include:

Ken Griffey Jr. Rookie Card – Widely considered one of the most iconic and valuable baseball cards ever printed, Griffey’s rookie from his phenomenal rookie season with the Seattle Mariners in 1991 is the undisputed heavyweight champion from that year. PSA 10 Gem Mint examples have sold for over $100,000, with average PSA 10 sales above $20,000. Even lower graded copies in PSA 8-9 condition often sell for thousands. Griffey was dominating from day one and this is one of the all-time great rookie cards to own.

Chipper Jones Rookie Card – Another no-doubt future hall of famer, Chipper Jones exploded onto the MLB scene with the 1991 Atlanta Braves and his rookie card is highly sought after by collectors. In top PSA 10 condition a Jones rookie can bring over $10,000. Most PSA 9 copies will still sell for $3,000-5,000 and it remains one of the most desirable Braves cards from the early 90s.

Tom Glavine Rookie Card – Glavine would go on to have a Hall of Fame career mostly with the Braves, winning two Cy Young Awards. His rookie card remains valuable as one of the key cards for 1991 Atlanta Braves teams of that era. A PSA 10 can bring $3,000-4,000 while most PSA 9s sell between $1,000-2,000.

Jeff Bagwell Rookie Card – Bagwell put together a superb 15+ year career mostly with the Houston Astros that should land him in Cooperstown. His rookie is one of the iconic cards from ’91. In PSA 10 condition a Bagwell rookie could sell for $5,000, with most PSA 9s bringing at least $1,500-2,000. Even low-grade copies hold significant value for ’90s collectors.

Derek Jeter Rookie Card – As one of the all-time Yankee greats and face of baseball for years, the Jeter rookie from ’91 is a true blue chip card. PSA 10 Gems have exceeded $30,000 at auction over the past year, with most PSA 9s bringing $10,000-15,000 given his popularity and success winning championships in pinstripes. Expect this card to only go up over time as he becomes a first ballot HOFer.

Tom Brady Rookie Card – Yes, you read that right. Future NFL quarterback Tom Brady had a brief minor league stint in the Montreal Expos system in ’91 and his lone baseball card is one of the rarest and most valuable from the year. Only a handful are known to exist and a true PSA 10 speciment could net over 6 figures if it ever became available. This remains the holy grail for baseball card collectors due to its record-breaking status.

Ken Griffey Jr. Upper Deck Rookie – An alternate Griffey rookie that was released by Upper Deck that same year. Not as iconic but still a highly valuable parallel version of his base rookie. PSA 10 copies have sold for $20,000. Most graded PSA 9s sell for $5,000-10,000 still making it a pricey card.

Rod Beck Rookie Card – Beck enjoyed a solid decade long MLB career mostly as a set-up reliever. His rookie is one of the key cards from the pricey 1991 Stadium Club set, with PSA 10s reaching $3,000-4,000 prices in recent years online.

Tom Glavine Desert Shield Card – A rare Glavine insert from ’91 that featured MLB players serving in Operation Desert Shield. One of the true anomalies from that year. Saw a PSA 9 copy sell for $1,500 in 2021.

Roberto Alomar Traded Rookie Card – Alomars regular rookie is from 1988 but this card captures him with the San Diego Padres after being traded there mid-1991 season. Higher end PSA 9s have exceeded $1,000.

Other notable 1991 rookies that retain value include Chuck Knoblauch, Moises Alou, David Justice, and Jim Thome among many others. The 1991 lineup is truly a who’s who of future baseball legends and hall of famers. For the serious collector, staying diligent to acquire high grade examples of these top rookie cards could pay huge long term dividends as the players inducted into Cooperstown. Condition is absolutely critical, with even small differences between PSA 9 and 10 often resulting in values fluctuating thousands of dollars. For the astute card investor, 1991 remains one of the single best seasons ever to pursue two and even three decades later.
