An auction house announced that a new-in-box copy of Super Mario Brothers 2 for the Nintendo Entertainment System sold for over $80,000.

The 1988 video game had sold for $88,5000 and it was considered so valuable because it was still in the original packaging, which had never been opened.

The game had been found in the back of a walk-in closet in Floyds Knob, Indiana with a collection of other opened games.

The game had also been graded by WATA Games, a company that grades video games. After a game receives a grade, it is then sealed in a plastic container with the score printed on it.

This particular copy of Super Mario Brothers 2 had received a grade of 9.8 A+, which is one of the highest possible scores a game can achieve. Whoever purchased the game will be unable to play it unless they break the seal and open the game, thereby destroying its value.
