“It has been at the bottom of my office desk all the time since the day I bought it,” said the unnamed salesman in the statement. “I never thought about that at all.”
It is also one of the first copies of the game to be packaged in plastic paper, instead of having an adhesive seal, according to the auction company.
This particular version of the game went on sale in 1986, but Nintendo changed the packaging in early 1987, so only a relatively small number was sold.
“Since the production window for this copy and similar ones was so short, finding another copy of this same production performed under similar conditions would be the same as looking for a single drop of water in an ocean,” said Valarie McLeckie, director video games from Heritage Auctions. “Never say never, but there is a good chance that it cannot be done.”
The $ 660,000 price includes the buyer’s prize and breaks the previous record for a copy of the Super Mario Bros. game.
