Lite Brite
Time Magazine included the Lite Brite in its list of the top 100 toys in history. Released in 1967, it was very popular then and it still is. Back in the day, you can buy one from the store for $9.97. If you held onto an original one, you can sell it for $130 to $150!
Moon Shoes
We know that they look rather weird, but they made you feel like you were taking a stroll on the moon. For 40 years or so, these were all the rage. When they first came out during the ‘50s, they were sold for $37.52. These days, you can get as much as $200 for an original pair as long as it is in good condition!
