Happy Meal
As a child, being taken to McDonald’s was one of the most exciting moments imaginable. Not only did you get to eat their iconic fries, but you also got a toy! Depending on the Happy Meal Toy you own from the 1979 releases, you could be walking around with some extra cash you could do well with. From the release, certain themes have become popular (2002 Disney Characters) and could get you an average of $300 on eBay.
Furby
Who remembers these strange but adorable creatures? Furbies were incredibly lifelike for their time, with automatic moving parts and sounds that made them seem like real creatures. They also had plenty of personality! These 1990s toys were a big thing among kids, and the cool design – a mixture of a hamster and an owl – made it a standout. If you own one still in an unopened box, you could get an average of $900 for it.
