Polly Pocket
These Barbie-inspired toys were first designed in 1983 and later picked up by Mattel in 1998. Polly Pocket's claim to fame was the unique "Polly Stretch" rubber garments, which could be put on the dolls and removed with ease. If you got your hands on a set between the years of 1989 and 1998, they sell for over $200 each.
Luke Skywalker Action Figure
In 2015, Japanese fashion designer NIGO, the founder of Bathing Ape, recently let go of his Star Wars collection for over half a million dollars, including this extremely rare in-box Luke Skywalker figurine. Only 19 others are currently in existence. The Skywalker action figure sold for $25,000 on its own.
