Propworx, Inc. was an auction house specialising in the sale of science fiction memorabilia, run by Alec Peters, a noted American memorabilia collector of the genre.
Propworx was founded in in 2008 when Peters was given the exclusive rights to facilitate the sale of the production assets of the Battlestar Galactica franchise. The two auctions held in 2009 were well received and Propworx was later commissioned to facilitate the sales of other genre franchises such as Caprica, Iron Man, and Stargate.
Propworx, later handled the sale of the larger set pieces of the defunct Las Vegas Star Trek: The Experience exhibition in April 2010. This was a prelude to Propworx' first specialised Star Trek auction.
In August of 2012 Propworx announced via the RPF that it was closing its doors and subsequently filed for bankruptcy.
