A retro shop owner based in Waukesha, Wisconsin, located some 15 miles west of Milwaukee, discovered that he was holding on to a rare stash of NES carts in his storage room. According to Nintendo Wire<\/em><\/a>, these cartridges were never-before-seen versions of Duck Hunt and Super Mario Bros., which were some of the most popular games on the Nintendo Entertainment System. What\u2019s more important is that these haven\u2019t been opened, and the original owner said that these supposedly came directly from Nintendo of America. Their condition is so pristine that PSA (Professional Sports Authenticator) gave them extremely high grades of no less than 9.6, with five units getting the coveted perfect 10.<\/p>\n

Kevin Braun, the owner of the retro shop OneStopWonders, said that a person sold him the cartridges years ago and that they\u2019ve just been sitting untouched in his storage unit. The man said that his grandfather owned a business that recovered precious metals from circuit boards, and that this box was supposedly sold to him for salvaging. It\u2019s unknown how it ended up in storage instead of recycling, but Braun bought it from the seller, thinking he could resell it in his shop for around $10 to $15 each.<\/p>\n

Thankfully, he forgot about these cartridges until his friend and EIC of Nintendo Wire, <\/em>Jason Ganos, got a chance to look at them. When he saw the carts for the first time, Ganos knew that he was looking at something special but didn\u2019t realize how exceptional they were until he shared the find on a high-end gaming Facebook group. Two different people working as directors at different grading companies then reached out to him, telling him that there was something strange about these cartridges. They then asked for more photos of one cartridge and the manual and even told him to disassemble one unit for a deeper inspection.<\/p>\n

This is where he discovered that these cartridges were some of the last produced units made during the 40th week of 1993. The manuals weren\u2019t seen before, either, with the back page saying, \u201cmaintenance or service,\u201d whereas previous known versions said, \u201cmaintenance or repair.\u201d Because of these finds, he proceeded to take a flight to PSA in California early the next morning, where the grading company confirmed its authenticity. <\/p>\n

It seems that the cartridges in the box were made as replacements for warranty repairs or refurbished consoles, or as part of a bundle that never saw release. We would never know which is true, though, unless Nintendo of America confirms why they were made. If you\u2019re an avid collector or simply want to get your hands on an original Nintendo game that hasn\u2019t been released, three carts will be auctioned off at Goldin Auctions<\/a> starting August 12. <\/p>\n

It\u2019s unclear how much these carts will go for, but it\u2019s estimated that they\u2019d cost at least four digits, with the perfect 10s possibly hitting five digits. This is possible, given that an ultra-rare NES Gold Nintendo World Championships cartridge auction sat at $77,000<\/a> and probably sold for a much higher price. So, if you want to get your hands on this, you\u2019d better have a war chest of at least $100,000 to guarantee that you can get one \u2014 just don\u2019t blow on it<\/a> if you insert it in your NES console and it doesn\u2019t work for the first time.<\/p>\n<\/article>\n
