Luke Skywalker's Lightsaber
One of three lightsabers built for the Sarlacc Pit sequence in Return of the Jedi, Luke Skywalker's Lightsaber is a highly rare piece of Star Wars history. This particular prop is made from metal, brass, and rubber, and was used for several close-up shots of R2D2. It's not the one that got fired up in the air — that one was plastic, to keep a metal projectile away from Han, Chewy, and the rest of the crew — nor is it the "hero" version that you see in Luke's hand afterward. As a result, this lightsaber has elements of both the other props and has a chipped edge along the top rim that's also visible in the film, lending it an extra bit of authenticity.
