Like many toys, action figures often have a thriving second life on the collectors' market. And these five figurines are at the very top of the heap—fetching thousands of dollars each at auction. These are the most valuable action figures out there:
5. Soundwave, Transformers
Year: 1984
Company: Hasbro
Value: $4,000 (mint condition in box)
Soundwave was one of the most popular Transformer from the original Hasbro line and it has become a tough action figure to come across today.
4. Computron, Transformers
Year: 1986
Company: Hasbro
Value: $6,500 (mint condition in box)
This Transformer was only available in a gift set and was a combination of five other techno-bots (Scattershot, Afterburner, Lightspeed, Nosecone, and Strafe).
3. Kamala, WWF
Year: 1992
Company: Hasbro
Value: $9,600 (mint condition in box)
Kamala's trademark is a moon painted on his stomach. However, when Hasbro released the figure, it had a yellow star. It's rumored that only 24 of the moon belly version exist.
2. Optimus Prime, Transformers
Year: 1984
Company: Hasbro
Value: $12,000 (mint condition in box)
This 1984 action figure was the first production of Optimus Prime and it is nearly impossible to find in its original box.
