This week a copy of Super Mario Bros., at first glance indistinguishable from the one gathering dust in your parents’ attic, sold at auction for $100,150. According to Heritage Auctions, this “set a world record for a graded game,” which means perhaps it didn’t have that much dust on it, according to Wata Games, which graded it at 9.4, or Near Mint. But, you might be wondering as you rush over your parents’ attic: Why is this simple cartridge, box, and manual worth over one-hundred thousand dollars?
