Unopened Super Mario Bros. game from 1986 sells for $660,000

The auction house said the video game was bought as a Christmas gift but ended up being placed in a desk drawer, where it remained sealed in plastic and with its hang tab intact until it was found earlier this year.

Heritage Auctions in Dallas said the video game sold Friday.

The auction house said the video game was bought as a Christmas gift but ended up being placed in a desk drawer, where it remained sealed in plastic and with its hang tab intact until it was found earlier this year.

“Since the production window for this copy and others like it was so short, finding another copy from this same production run in similar condition would be akin to looking for single drop of water in an ocean,” said Valarie McLeckie, Heritage’s video game specialist.

Heritage said it is the finest copy known to have been professionally graded for auction. Its selling price far exceeded the $114,000 that another unopened copy that was produced in 1987 fetched in a Heritage auction last summer.
