Sealed Super Mario Bros

So it's difficult to surpass Super Mario Bros as the most expensive and rarest video game of all time. But how is that possible? It's possibly the most well-known game of all time, if not the most. Everything hinges on the specifics.

A sealed edition of Super Mario Bros sold for an astounding $660,000 in April 2021. The game was sealed, undamaged, and basically flawless because it had been stored in a drawer unopened for 35 years. However, it wasn't the most expensive game ever. A few months later, another copy of Super Mario Bros sold at auction for an astounding $2 million, setting a new record for the highest money ever spent on a video game.

This copy was flawless and professionally graded, much like the $660,000 copy. Additionally, it was only printed in a single copy, making it more uncommon than the typical Super Mario Bros game. With those elements together, it might be the only game in existence that satisfies all of those requirements.
