A rare copy of Super Mario Bros. for the original Nintendo gaming system just sold on eBay for $30,000.
Normally, Super Mario Bros. sells for about $15 on eBay. It’s an easy game to get because it was shipped with the system. Everybody got a copy. Well, almost everybody.
In the beginning, Nintendo did NOT include Super Mario Bros. Instead, they sold it separately. That’s why this game is worth 30 grand. It's one of the rare copies – in a sealed box with mint-condition packaging – of Super Mario Bros. that wasn’t bundled with the system. (Mashable)
