In 1985 Nintendo, Kyoto, Japan, introduced the Nintendo Entertainment System, and 8-bit game console. It was accompanied by Super Mario Bros., the best-selling video game as of 2008 with 40,000,000 copies sold.
On February 6, 2019 an extremely rare Super Mario Bros. game cartridge sold for $100,150 at auction, establishing a price record for a game cartridge, according to 01net.
"The colossal amount is primarily explained by the rating given to the game by the company Wata Games, a strong reference for those with expertise on video games. The game, in an astonishing state of conservation, was awarded a score of 9.4 out of 10.
"Between 1985 and 1986, the cartridges of Super Mario Bros ... were dispersed in 11 variants.
Two of them were distributed only in New York and Los Angeles, in order to test the market. The distinctive sign of these two variants is a small sticker to seal the box. The lot sold at auction was the last remaining copy of the two test versions known to date" (https://www.barnebys.com/blog/the-little-italian-plumber-raises-prices-and-heads-nintendo, accessed 1-2021).
