The gold Punch-Out!! Special cartridge was given out as a prize during the Nintendo Famicom Golf US competition. This version of Punch-Out!! was actually the very first release of the game and has some differences from the retail release, including wording, color, and music variations. There’s not even a final bout, the game ends after you defeat Super Macho Man.
Apparently there were 10,00 of these released. 5,000 for high scorers in the contest, 1,000 randomly to people who scored a hole in one in the contest and the last 4,000 randomly to those with certain numbers on their ranking.
I can’t remember what these normally fetch, anyone happen to know off hand?
