Six Million Dollar Man
The Steve Austin doll was the heart of Kenner's line of Six Million Dollar Man-themed toys. The action figure stood 13" tall and included several interactive items, like a bionic eye that the user could actually look through, and skin that rolled back to the interchangeable bionic elements underneath. In its original packaging, this toy is worth up to $800 on eBay.
Evel Knievel
Evel Knievel has gone down in history as America's number one daredevil. The action figure version of this famous motorcycle stuntman was extremely popular. Between 1972 and 1977, Ideal Toy Company released several Evel Knievel-related merchandise items, which amounted to over $125 million in sales. A factory-sealed Evel Knievel toy can resell for over $300.
