Navy CPO Nintendo Contra challenge coin. If you’re a military, Navy, or Nintendo challenge coin collector, this is a must have for the collection. These very rarely go up for sale. The attention to detail is crazy good retro to the original game in the 80s. It’s heavier than most coins. I’ve also listed the rare Nintendo cartridge challenge coin as well.
