Nintendo cartridge sells for £10,000.

From the Daily Mail:

A gaming enthusiast has paid a whopping £10,800 on eBay for an extremely rare Nintendo cartridge.

Despite the astronomical cost the buyer, JJ Hendricks, was happy with his purchase saying the game was the 'Holy Grail of Gaming.'

The special cartridge was created for the Nintendo World Championships in 1990, and featured three mini games of Super Mario Bros, Rad Race and Tetris.

Eager competitors in the U.S had to score points within a time limit of six minutes and 21 seconds for each game.

The competition consisted of eight rounds, separated into three age groups and ended with a grand final at Universal Studios.

Only 116 special cartridges were made and 26 gold versions were given out to winners and runners-up in a Nintendo Power magazine contest.
