Company Description
To celebrate their 100th anniversary in 1990, Nintendo launched its first annual nationwide video game competition series: the Nintendo World Championships. Throughout the games, contestants played a special Nintendo World Championships cartridge for NES which contained 3 minigames: Super Mario Bros., Rad Racer and Tetris. 26 gold cartridges of the game were distributed to Nintendo Sweepstakes winners. At the same time, parents of contestants became irate that their children did not get one. Officials then decided to give the 90 finalists grey cartridges, though some cartridges were also given to Nintendo employees. People speculate that between 350 - 400 copies were ultimately produced, but the number that still exists and is in good condition is much smaller. Therefore, this cartridge is considered to be the one of the most valuable NES cartridges ever released.
