A sealed copy of Super Mario Bros. just broke the record for the most expensive game ever sold.
A mint copy of the 1985 game sold for $114,000 on Heritage Auction. The record was previously held by the same game and was sold for $100,000.
The game was graded at a 9.4 out of 10 which means the game was in near perfect condition.
