We're still amazed that the popularity of Star Wars doesn't just stay the same, it seems to grow with every new movie release. People are Star Wars mad, so it's not exactly a shock that all of the action figures of the past are quite valuable in the present. Like Barbie, not all Star Wars action figures have huge monetary values attached, but some will definitely show their worth.
In the $2,000 to $3,000 range you have Boba Fett (1979), Boba Fett (1985), Han Solo (1980), Death Star II (2005), and C-3PO (1999). For about $4,000 to $8,000 you've got Chewbacca (1977), Death Squad Commander (1977), Boba Fett LEGO (2010), Darth Vader (1983), and Anakin Skywalker (1985). The rarest of the gang is the original Jawa with vinyl cape (1977), which is worth around $18,000.
