Like many of the toys from our childhood, Hasbro was responsible for bringing the visions of mega-franchises like Transformers to life. The 1984 Hasbro Optimus Prime Series 1 Transformer was a toy that coincided with the start of The Transformers animated TV series.
The show was based on the toy and included Optimus Prime, who is perhaps the most famous of the original Transformers. This first generation toy can sell for thousands if it is truly original and in great condition. Professionally classified toys in protective boxes are the ones that sell the most.
