The Original Monopoly
There are many different versions of Monopoly, but one version stands out above the rest, regardless of which expensive properties are on the board. In 2011, the hand-drawn version created by Charles Darrow in 1933 brought in an incredible $146,500 (real money). If you have an older version of Monopoly, you will almost certainly find yourself in a pile of money… real money.
Game Boy
The Game Boy not only ate up thousands of batteries in our house, but it also ate up hours that I could have spent doing my homework. It was difficult to do anything else with games like Super Mario, Zelda, Tetris Attack, and Adventure Island. Limited edition Game Boys can now sell for over $1,500, making them one of our childhood’s most valuable toys.
