A retro game shopper in Wisconsin has unearthed one of the most unexpected hauls in recent collecting history: 97 sealed copies of a previously undocumented Super Mario Bros. cartridge variant. According to a Time Extension report, Nintendo Wire’s Jason Ganos noted that “Something was strange about these cartridges” while browsing a Wisconsin retro store, kicking off a discovery that has the wider community buzzing.
The find is remarkable both for its scale and for what the cartridges appear to represent. Reports describe the variant as never-before-seen, meaning collectors and historians had no record of it prior to this stash surfacing in the wild. A single sealed copy of an unusual Super Mario Bros. release can already command eye-watering prices on the secondary market, so a run of 97 identical sealed copies represents a staggering concentration of one variant under a single roof.
Why a New Mario Variant Matters
Super Mario Bros., originally released for the Nintendo Entertainment System in 1985, remains one of the most cataloged and analyzed cartridges in gaming history. Collectors document every known label revision, board variation, and regional release, partly because the game’s cultural weight keeps demand high decades after launch. Earlier this decade, rare print runs and prototype versions of the title have sold at auction for sums that redefined what retro cartridges can be worth, fueling an entire subculture of variant hunters.
That context is what makes Ganos’s find so significant. A new variant, once authenticated and documented, reshapes the known catalog of one of the medium’s defining titles. Researchers will want to determine whether the cartridges represent a regional test print, a canceled retail run, or a minor production tweak that simply escaped collectors’ attention for decades. Whatever the answer, the discovery adds a new chapter to the history of one of the most reproduced cartridges ever manufactured.
What Happens Next
The collector community will be watching closely as more details emerge. Documentation, authentication, and provenance are likely to dominate discussion in retro gaming circles in the coming weeks. For longtime fans of the franchise, the discovery is also a reminder that physical cartridge hunting still pays off; sealed stock from the 8-bit era has a way of turning up in the unlikeliest places, from estate sales to small-town retro shops.
