Hero lightsabers from the franchise have been key chases for "Star Wars" collectors when they appear at public auction. Three lightsaber props have sold for $100,000 or more at Heritage in recent years, including Mark Hamill's "Luke Skywalker" hero lightsaber from "A New Hope" and "The Empire Strikes Back," which fetched $450,000 in June 2017.

The prop is believed to be the first of its kind to go on the market, as the other few lightsabers left from the original trilogy were instead cycled through museums.
