What’s the big deal about factory seals? If you’ve browsed through trading cards on eBay, you’ll quickly notice that factory-sealed sets, packs, and boxes sell for significantly more than their opened counterparts. As anyone who has tuned into an episode of EconTalk with Michael Munger will tell you, the answer lies in transaction costs.
The reasoning is straightforward: a factory seal serves as proof that no one has meddled with the cards inside. This is crucial, especially for vintage wax packs that can be easily opened, sorted, and resealed with inferior cards. The same principle applies to card sets. A dishonest seller could easily open a set, extract the top cards, and swap them out for lesser-quality ones. In fact, I’ve had to lower the prices on unsealed sets I’ve sold on eBay, as buyers can’t be certain I haven’t cherry-picked the best cards—or that the sellers I purchased them from didn’t do the same.
Take the 1989 Fleer baseball set, for example; it includes some highly sought-after cards. This set boasts rookie cards of Hall of Famers like Ken Griffey, Jr., Craig Biggio, and Randy Johnson. It also features one of the hobby’s most infamous error cards, the Bill Ripken card.
Legend has it that during a photo shoot, Ripken grabbed the nearest bat and posed for the camera. Unfortunately, during the initial production run, an expletive was visible on the bat’s knob, legible to anyone who received the card. Ripken has claimed he scribbled that profanity on the bat to claim ownership.
Once the error was spotted, Fleer promptly halted production of the Ripken card and produced several corrections—one with the profanity crossed out, another whited out, and a third with a black box covering it. Even these corrected versions carry a few dollars in value, despite Bill Ripken’s career being overshadowed by his brother, the legendary shortstop Cal Ripken.
As with any tale of notable blunders, conspiracy theories abound. How could such an obvious mistake slip past Fleer’s quality control? Given the comedic missteps in the 1990 Donruss set, which included the famous Juan Gonzalez reverse negative card and Nolan Ryan cards with swapped backs, I’m not surprised the Ripken card made it through. The conspiracy theorists speculate whether this error was a deliberate attempt to generate buzz or merely a fortunate oversight. If it was a stunt, it certainly succeeded: 37 years later, we’re still discussing it, and unopened boxes of 1989 Fleer cards continue to outshine those from Topps, Donruss, Score, and Bowman in value.
Remarkably, all of this unfolds without government intervention. There’s no requirement to submit cards to an official authenticator or join a dealer’s guild to trade baseball cards and collectibles. The stark price difference between sealed and unsealed sets illustrates that effective mechanisms exist to prevent fraud. If such a system can thrive in the world of trading cards, why wouldn’t it work for matters of greater significance?
