An auction this September will feature the lightsaber used by Darth Vader in The Empire Strikes Back. The prop is expected to fetch up to $3 million, the auction house estimates. Also going up for bid are Sauron’s helmet from The Lord of the Rings and Indiana Jones’ belt, bullwhip and pistol holster from Indiana Jones and the Last Crusade.

The 'Star Wars' prop is part of a new big-ticket auction also featuring Sauron's helmet from 'Lord of the Rings.'

The coveted prop that was used in the films 'The Empire Strikes Back' and 'Return of the Jedi' is soon hitting the block from Propstore.
