The baseball card company Upper Deck made its debut in 1989, revolutionizing the industry with its quality cardboard stock and attention to detail. Like any mass produced product, errors made their way into packs. Some 1989 Upper Deck errors have become enormously valuable collectors items today due to their rarity and significance in the hobby.
One of the most famous and coveted errors from the inaugural Upper Deck set is the Ken Griffey Jr. rookie card missing the banner. Griffey’s rookie is one of the most iconic cards in the hobby for good reason – his graceful swing and effortless talent showed he was destined for greatness from the start. A small number of Griffey rookies were missing the trademark Upper Deck banner at the top of the card front. This subtle error made these cards instantly stand out from the regular issue. Today PSA Gem Mint 10 examples of the Griffey bannerless rookie have sold for over $30,000 due to their scarcity.
Another significant rookie error is the Mark McGwire card with flipped front and back images. McGwire, like Griffey, was immediately identifiable as a future star in 1989 with his prodigious power. But a small batch of his rookie cards had the front image, which shows McGwire launching a home run, mistakenly printed on the back instead. Likewise, the standard statistical information usually found on the back was wrongly placed on the front. Examples of this intriguing flipped image McGwire rookie have reached over $15,000 at auction.
While star rookies tend to attract the biggest prices, key errors on cards of established veterans from the 1989 Upper Deck set also hold significant value. A notable example is the Nolan Ryan card missing the copyright information along the bottom edge. Ryan was a surefire Hall of Famer by 1989 after over two decades of dominance on the mound. But without the usual Upper Deck copyright on a small number of his cards, they stood out as abnormal. Currently, PSA 10 examples of the 1989 Upper Deck Nolan Ryan missing copyright error have sold for upwards of $7,500.
Errors were not limited only to major stars though. Even relatively obscure players from the 1989 Upper Deck set have errors that excite avid collectors. A unique error is the Kent Hrbek card having its front image reversed left to right. As a solid veteran on consistently competitive Twins teams, Hrbek was a known name but not an all-time great. Yet due to the rarity induced by this odd front image reversal, examples have reached around $2,500 at auction.
On occasion, production mistakes resulted in entire sheets missing colors on specific cards. One such dramatic error was a sheet missing the red tint that usually accentuated highlights, logos and photographs across every card surface. While less identifiable than individual player errors, finding an unbroken full sheet of 1989 Upper Deck cards lacking red adds major condition census value. Just a few have been discovered, with one full sheet recently selling for over $11,000.
The 1989 Upper Deck set broke new ground with its photographic reproduction quality far surpassing other contemporary issuers. Like any mass produced item, a small number of production irregularities occurred despite quality control efforts. Some 30 years later, the most significant 1989 Upper Deck errors have become highly coveted by savvy collectors willing to pay big money for their statistical rarity within the larger set checklist. As exciting rookie seasons translated into storied careers for players like Griffey and McGwire, their error cards from that pioneering Upper Deck release have gained legendary status matching their on-field prominence.
