Until recently, the record for the most expensive videogame relic belonged to a very rare working prototype of the Nintendo Play Station, sold for $ 360,000 in February 2020. If instead we limit ourselves to video games, at the end of 2020 a sealed copy of Super Mario Bros. 3 was sold for 156,000.
Figures that pale in comparison to the $ 660,000 paid by those who won a Super Mario Bros. cartridge for NES still sealed and perfectly preserved. What makes this copy of a game theoretically available used for less than thirty euros particularly attractive to collectors are some peculiarities of the package.
There are a few key factors that make this copy particularly valuable. First of all the perfect conditions, then the belonging to the fourth reissue, the one in which a particular identification code is missing, then the trademark symbol next to the phrase Nintendo Entertainment System, which was added only in 1987 in all the Nintendo game boxes.
