2. Blythe Doll: $2,000
Inspired by the popular '70s Margaret Keane paintings with the big eyes, the 1972 Blythe dolls hit stores without much fanfare. Even though they had a fun feature, where you could change their eye color with the pull of a string, the toy just didn't make it too far off the shelves.

But today that's a whole different story, where these collector's dolls now fetch up to $2,000 at auctions.
