For kids growing up in the '80s, He-Man, GI Joe, and Transformers made up the "Big Three" of toys. Decades later, these old toys can cost between US$ 50 and US$ 500 on the market. For example, a Cobra Commander figure sent in the mail can fetch $ 100 on sites like eBay.

The boxed versions of these action figures will always be the best sellers as the characteristic of the box indicates that these figures are of high quality. The original Optimus Prime Year One figures have been known to retail for US$$300, while a Transformers Jetfire can fetch US$200. A boxed vehicle such as the GI Joe Dreadnok Thunder Machine can even fetch US$500.
