Lite Brite
Named one of the top 100 toys of all time by Time Magazine, the Lite Brite was and still is, incredibly popular ever since its release 1967. Its average price used to be $9.97, but now an original vintage one could flip for $130-150.
Moon Shoes
While these shoes might look weird, they made you feel as if you were walking on the moon – hence the name. They were popular for around 40 years! Back when they were released in the 1950s, they cost $37.52. Now you can flip an original pair for as much as $200. Naturally, they would need to be in great condition to meet that price.
