This is a near complete collection of Nintendo NES NTSC games, as there are only three missing titles (Pac-man, Bubble Bobble 2, and Stadium Events). NTSC is the format used in Canada, Japan, Mexico, North America, and parts of South America and Asia.
The starting bid is $6,495 and the shipping is $400, so the average game price is just under $10. There are also many rare NES Nintendo games that can sell for well over $50. The seller has put together a huge list of all 677 games and their condition.
