Game Boy
The Game Boy ate up the juice of so many batteries in our homes. Aside from this, it also ate up all the time that we could have spent on our studies. It was hard to think of anything else when we were so focused on Tetris Attack, Adventure Island, Zelda, and Super Mario. You should have held onto your limited edition Game Boy since it is now worth $1,500!
Hot Wheels
When you are a child, there is no way for you to afford any car at all. This is where Hot Wheels comes in. The company makes miniature versions for kids to play with! There have been about 4,000,000,000 units made, and at least a few of them are worth a lot of money. A good example would be the limited edition 1969 prototype of the Volkswagen Beach Bomb. It now has a value of $125,000. Whoa.
