2. Vintage Video Games and Consoles

Do you have a box of old video games your children left behind when they moved out? Original Nintendo Entertainment System (NES), Super Nintendo, and Sega Genesis cartridges are fetching unprecedented prices. The key to high value in the video game market is the packaging. A game cartridge alone might sell for twenty dollars, but that exact same game in its original cardboard box, complete with the instruction manual, can sell for ten times that amount.

Unopened, factory-sealed games from the 1980s and 1990s routinely command thousands of dollars at specialized auction houses. Even the consoles themselves retain solid value, provided they are clean, functioning, and include the original cords and controllers.
