A uniform worn by Leonard Nimoy as Spock in Star Trek is expected to make around �50,000-70,000 ($78,058-109,281) in a sale at the Prop Store.
The auction will be held at London's BFI IMAX in association with Odeon cinemas on September 23.
Nimoy, who died earlier this year, was launched into stardom after taking on the role of Spock. He played the character in the show's original run from 1964-1969 as well as in an animated series and various films.
His huge popularity, which extends beyond the Star Trek series due to numerous appearances in other media, ensures a strong market for his memorabilia.
A set of prosthetic ears worn by Nimoy on the show sold for $10,000 at Bonhams in 2008.
Other lots in the sale include a Stormtrooper's helmet from Star Wars: The Empire Strikes Back that is valued at �40,000-60,000 ($62,446-93,669).
In 2013, a Stormtrooper's helmet signed by George Lucas sold for $245,000 at Sotheby's New York.
