Contra on the Nintendo Entertainment System (NES) is regarded as a collector's item by video game enthusiasts. Contra is a popular run-and-gun shooter game from 1988 that is recognized for its difficulty and fast-paced gameplay. It was a hugely significant game in the 1980s and early 1990s, helping to popularize the shooter genre. Collectors value the game because of its popularity and significance as a classic game, as well as its relative scarcity. The game was initially released in big quantities, but many copies were lost or destroyed over time, making complete and original versions of the game difficult to find. Collectors prize the game's packaging, which includes the original box and manual, especially if it is in good shape. Also, some versions of the game are more valuable than others, such as the original "Contra" release and the subsequent "Contra Force" release. A round quality seal is located on the front of the box. A round quality seal can be found on the cart label.
