The 1990 Score baseball card set is one of the more popular vintage sets from the late 80s and early 90s. While the base cards from the set don’t hold huge value on their own, there are several rare errors and variations that can be quite valuable for collectors. Let’s take a deeper look at some of the more notable 1990 Score baseball card errors and variations that are worth money for collectors today.

One of the biggest errors from the 1990 Score set involves a printing plate error on the Greg Maddux rookie card. On a small subset of Maddux rookie cards, the printing plate was misaligned, causing part of the next card in the sheet to bleed over onto the right side of the Maddux card. This error is easily one of the rarest from the entire set, with experts estimating less than 10 examples are known to exist. In top graded condition, a miscut Maddux rookie card could sell for well over $10,000 due to its extreme rarity and significance as one of the best rookie cards from the late 80s/early 90s.

Another popular error involves the Robin Yount card. On a small number of Yount cards, the printing plate was miscut, extending the image of Yount further down the right side of the card. Like the Maddux error, this introduced part of the next card in the sheet onto the Yount card. Examples of the Yount miscut error in top condition can sell for $500-1000 depending on the severity and centering quality. It’s a much more obtainable error for collectors compared to the Maddux, but still holds solid value recognition among error card collectors.


In addition to miscuts, there are also several missing/extra color errors that occur throughout the 1990 Score set. The most famous example involves the Nolan Ryan card, where on some copies the photo is missing the blue/teal color, making Ryan’s uniform appear solid gray. High grade examples with strong eye appeal can sell in the $200-400 range. Other notable missing/extra color errors include the Ozzie Smith (missing teal), Mark McGwire (extra teal), and Tony Gwynn (extra teal) cards. These errors usually sell in the $50-150 range depending on the player and condition.

Beyond specific player errors, there are also a few errors that occurred at the set level during production. The most valuable of these is known as the “blue tint” error, where a run of cards were printed with an overall blue/teal tint instead of the normal colors. Ranging from commons to stars, cards with this error command big premiums simply due to the visual appeal and rarity. Examples can sell from $20-200+ depending on the individual card and demand. Another set-wide error involved gum stains on many of the cards during packaging. While not as valuable as true printing errors, gum-stained examples can still add a premium over normal copies in higher grades.


The 1990 Score set also saw its fair share of odd test prints and proofs that make their way to collectors. Among the most notable are gold foil test prints that were apparently used early on during the design process. Only a tiny handful are believed to exist, and they sell for thousands when they surface due to their one-of-a-kind status. There are also a small number of photo variation proofs known, where cards were printed without statistics/team logos to test photos. While not quite as valuable as the gold foil proofs, these photo variations still demand 4-figure prices.

When it comes to 1990 Score errors and variations, condition is absolutely king. The rarest errors from this set can be quite valuable, but only in the highest certified grades of Mint or Gem Mint. Even top tier errors like the Maddux miscut lose a tremendous amount of value in lower grades. As such, collectors need to be very careful when buying vintage error cards to ensure they are indeed in the claimed condition. Reputable grading from services like PSA or BGS helps provide buyer confidence and protects long term investment potential.


For collectors looking to pursue valuable 1990 Score errors, the best approach is thorough research and patience. Unless deep pocketed, it may take years to find some of the key pieces like the Maddux miscut. In the meantime, lesser errors and variations can still offer an affordable entry into the world of vintage error card collecting. With time and persistence, a collection of 1990 Score errors can become quite valuable and appealing to both error card and baseball card enthusiasts alike. The unique stories and rarities from this set make it a fun niche to explore within the hobby.

While most 1990 Score base cards don’t hold huge individual value, the various errors and production anomalies from the set offer collectors opportunities to acquire truly one-of-a-kind pieces of sports memorabilia. From miscuts and missing colors, to odd test prints and proofs, 1990 Score had its fair share of mistakes that have become highly sought after – and valuable – among today’s error card collectors. With the right combination of condition, eye appeal, and significance, some examples can sell for thousands. For patient collectors willing to do their research, building a collection focused on the rarest errors from this classic set offers an exciting long term investment prospect within the baseball card hobby.
