The original Game Boy
Everyone has an old Game Boy -- but don't get too excited. The real value comes with the original 1992 version of the portable gaming device, especially the iteration bundled with Tetris. Lightly used models can land you a few hundred dollars, while mint-condition editions can fetch upwards of $1,500. But honestly, what monster would buy a Game Boy and leave it unopened?
You almost definitely have a mountain of VHS tapes littering your basement floor, and most of them aren't worth more than the rewind fee at the store that was once your local Blockbuster. However, there are some examples of rare tapes that are worth thousands upon thousands of dollars. These coveted titles range from cult classics to first editions of classic films like Star Wars, King Kong, and Beauty and the Beast.
