If you convert that figure into dollars, it's $13,000 or £10,800.
The cartridge contained a demo of three games - 'Super Mario Bros.', 'Rad Racer' and 'Tetris - and was awarded to contestants of the Nintendo World Championships in 1990. In total, only 90 of these kind of cartridges exist in the world - and it's why they're so heavily sought after, and why the sale of one of them is quite news-worthy.
Ars Technica reported on the sale, which began when a customer walked into Seattle's Pink Gorilla Games, a retro-gaming shop, with a plastic bag full of NES cartridges. Among them were standard enough cartridges like 'California Games', 'Strider' and 'Spy Hunter', but there at the bottom of the bag was one of the most valuable game cartridges in the world.
After a bit of due diligence and authenticating, the customer was then handed a cheque for $13,000 after being told that the cartridge was extremely valuable. Of course, most people would probably hold on to the cartridge - and maybe try get a higher price on eBay or something. Not so, according to Cody Spencer, the co-owner of Pink Gorilla Games.
"I think what led him to being comfortable with it was how up front I was about everything... Literally, we could've gotten that [cartridge] for, like, 20 bucks. Or a dollar! He had no idea at all," Spencer told Ars Technica.
While $13,000 is definitely a tidy sum for a game cartridge that's three decades old, it's by no means the most expensive price ever paid for a game. A one-of-a-kind Atari game, 'Gamma Attack', was offered for sale for $500,000 once in 2008.
