Yes, some action figures are worth money. The value of an action figure depends on several factors including its rarity, condition, whether it's still in its original packaging and its age. Some valuable action figures include certain versions of Star Wars characters, which can sell for hundreds or even thousands of dollars. For example, a 1978 Luke Skywalker action figure was sold for $25,000 in 2015. Other valuable action figures include certain G.I. Joe figures, Transformers and figures from the Masters of the Universe line. However, not all action figures are valuable and it's best to research specific figures to determine their potential worth.

An action figure is a poseable character toy figurine, often made from plastic and based on popular characters from movies, video games, television programs, or comic books. These figures are typically marketed towards boys and adult collectors. The term "action figure" was first coined by Hasbro in 1964 to market their G.I. Joe figure to boys as dolls were often marketed towards girls. Action figures can include features such as movable limbs, interchangeable accessories and in some cases, voice boxes for sound effects.

The most popular action figure of all time is arguably G.I. Joe. Introduced by Hasbro in 1964, G.I. Joe is often considered the first action figure and it has remained a staple of children's toy boxes for over five decades.
