Rare Nintendo Game Cartridges Discovered in Wisconsin Storage Unit
A forgotten storage unit in Waukesha, Wisconsin, yielded a treasure trove of nearly 100 rare Nintendo game cartridges, including an unknown version of Super Mario Bros. Experts believe these could fetch millions at auction.

An astonishing discovery in Waukesha, Wisconsin, has unearthed a collection of rare Nintendo game cartridges that experts suggest could be worth millions of dollars. The find, comprising almost 100 copies of games including a previously undocumented version of Super Mario Bros. and Duck Hunt, has sent ripples of excitement through the collector community.
The cartridges are distinct from known editions, reportedly produced two years after the last official production run. Key differences noted by enthusiasts include unique labels, specialized screws, distinct manuals, and altered motherboards, indicating a significant anomaly in Nintendo's production history. The seller’s account suggests these games were intended for destruction, sent to a metal recovery service for recycling, but miraculously escaped the melting pot.
Professional grading services have begun assessing the condition of the cartridges, with some achieving top marks from the Professional Sports Authenticator (PSA) for Nintendo Entertainment System (NES) games. This level of preservation is rare for vintage gaming hardware and significantly boosts their potential market value.
A Collector's Dream or a Production Anomaly?
The existence of these cartridges raises intriguing questions about Nintendo's past operations. While the exact circumstances of their production and subsequent survival remain somewhat mysterious, speculation points to them being test units or a special limited run that was never widely released. The meticulous detail differentiating them from standard releases—from the hardware components to the packaging—suggests a deliberate, albeit clandestine, effort.
The market for retro games has seen substantial growth in recent years, with rare items commanding astronomical prices. High-profile auctions have previously seen classic Nintendo titles fetch hundreds of thousands of dollars. This latest find, with its sheer volume and unique characteristics, could potentially shatter previous records, especially if the pristine condition of many cartridges is confirmed by further grading.
This event highlights the enduring appeal of vintage gaming and the potential for unexpected windfalls in overlooked collections. As details emerge about the specific version of Super Mario Bros. and Duck Hunt, its historical significance and monetary value will become clearer. The Waukesha find serves as a potent reminder that hidden treasures can still be discovered in the most unexpected places, even within the realm of video games.
