Of course, it'll lose value the moment it's opened

An unopened copy of “Super Mario Bros.” for the Nintendo Entertainment System (NES) reportedly fetched the highest selling price for a video game, selling for $114,000 at an auction held by Heritage Auctions on July 10. It was the highest-graded “Super Mario Bros.” title ever, having been graded 9.4 A+ by WataGames, indicating that it is in “exceptional,” near mint condition.

“The demand for this game was extremely high, and if any lot in the sale could hit a number like that, it was going to be this one,” Heritage Auctions video games director Valarie McLeckie said in a press release.
