Rare copies of Super Mario Bros. 3 could potentially sell for around $30,000.

An extremely rare copy of Super Mario Bros. 3 for Nintendo has been sold for a whopping $30,000. While most copies of the game sell for around $15 or $30, this particular edition was priced much higher due to the fact it was sold as an original game, rather than as a bundle with the Nintendo Entertainment System, as most editions of the game were.
