In 1991, Nintendo toured US campuses with Nintendo Campus Challenge. After this national tournament, all the cartridges were destroyed save one, which was retained by a Nintendo employee and sold to US collector Rob Walters at a 2006 New York garage sale. In 2009, the game was resold on eBay for $20,100 (£12,350).
