There is an auction on ebay for Nintendo Campus Challenge 1991. There is only one of these in the world and it's a very sought after piece of Nintendo gaming history.
In 1991 Nintendo hosted a second Nintendo World Championship but toured 58 college campuses so they called it the Campus Challenge. Nintendo made a special cartridge just for this event that had Super Mario 3, PinBot, and Dr. Mario. After the competition was finished all of the cartridges were supposed to be destroyed, but in 2006 this cartridge appeared at the garage sale of an ex-Nintendo employee.
The auction started at $0.99 with no reserve but the price already up to $3,250. Where will it end up? We will be sure to update the VGPC price for Nintendo Campus Challenge 91 once the auction closes.
The game sold for a record $20,100. A user on youtube posted a video showing the last two minutes of the auction as the price increased from $8,500 to $10,000 and then to $20,100 with 2 seconds left.
