Have you ever wanted to own Data’s head? You may have that chance this weekend.

Premiere Props is auctioning off some Hollywood memorabilia Sept. 28, including some props found in the Star Trek movies and television series. One, Data’s head, was made in the likeness of Brent Spiner for the “Star Trek: The Next Generation” episode “Phantasms.” The starting price is $500, but it’s estimated to pull in at least $4,000.

The head, according to the website, is made with “Data-colored” foam latex, faux hair and plastic eyes. If you turn it around and look at where the neck is severed, you can even find the prop circuity that makes up Data’s positronic matrix.

If you’re a Data fan, then you can also vie for a chance to get the jumpsuit uniform Spiner wore in 1996’s “Star Trek: First Contact.” The uniform is expected to go for at least $2,000, with the starting bid at $200. It is possible Spiner wore it for later Star Trek movies as well, including 1998’s “Star Trek: Insurrection.”

Other pieces in the auction include the proton collector from “Star Trek IV: The Voyage Home,” the plaque from the Son’a ship from “Insurrection,” a backlit control panel from the Enterprise bridge, a tricorder holster from TNG, phasers and tricorders from different series and films, and even a “signed” letter from “Star Trek” creator Gene Roddenberry.

We threw the “signed” in quotes because it was likely signed by Roddenberry’s assistant or secretary. But the letter, from 1967, was to a reporter with a Santa Monica newspaper, talking about the pressures of putting together Season 1 of the original series, and even providing confirmation that NBC had renewed the show for a second season. It’s even on the original “Star Trek” letterhead from Desilu.
