In a remarkable discovery, 97 Super Mario Bros./Duck Hunt NES cartridges were found in a Wisconsin warehouse, dating back to late 1993.15
These cartridges, which are among the last printed copies, were acquired by Kevin Braun's OneStopWonders shop.3
Jason Ganos, who transported the cartridges, expressed anxiety over TSA inspections during his flight to California.
The cartridges were originally part of a stock that Nintendo needed to offload quickly, leading to their recovery instead of disposal.
Of the original 100 cartridges, 97 remain, each individually wrapped and accompanied by a manual.4
Authentication by PSA revealed impressive grades: 60 at 9.8, 31 at 9.6, one at 9.4, and five achieving a perfect 10, a first for NES cartridges.
Experts suggest these rare finds could fetch between four to five figures at auction.
The auction is set for Aug. 12, 2026, at Goldin Auctions, making it a highly anticipated event for collectors.2
