1982 Skeletor Action Figure, $1,650
Skeletor was He-Man’s main nemesis, and he also happened to live in a pretty cool crib known as ‘Castle Grayskull.’ And despite him being the villain, everyone wanted a piece of him and his very impressive fortress. This particular figurine of Skeletor from 1982 is worth $1,650, but that’s as long as it’s never actually been played with.
