Lite-Brite
Ah, Lite-Brite. You might remember the infomercials about this toy. The Lite-Brite consists of a lightbox with tiny plastic pegs of different colors. The pegs slot into a panel and light up to create an illuminated picture, either by using a template or creating an image of our own. If you have one laying around, these artistic devices are worth $100.
Happy Meal Toys
Since 1979, the Happy Meal toy has been an integral part of every McDonald's Happy Meal experience. Some of these small trinkets have proven quite valuable—for instance, the 2002 collection of Disney-themed characters recently sold for $300.
