Star Trek auctions
A number of Star Trek auctions have been held during the history of the franchise. 

During the years of production, thousands and thousands of set pieces, props, wardrobe items, and other production materials have been acquired, as well as thousands of dedicated fans who will pay a hefty price to add parts of this historic series to their personal collections. In the past, franchise owner Paramount Pictures chose to keep the production inventory, to be used again in future episodes; but after the cancellation of , when there were no more Trek productions planned for the foreseeable future, Paramount's successor, new franchise owner CBS Broadcasting, decided to liquidate these assets in 2006 (though previous auctions liquidating smaller amounts of assets were held). This precipitated a number of high-profile auctions.

Butterfield & Butterfield Auction Galleries
Note: for all applicable listings only Star Trek-themed catalog covers are depicted has been a San Francisco-based auction house, founded in 1865. The auction house ended its independent existence in 1999 when it was bought by Internet auctioneer . In 1993 the auction house was commissioned to sell off the estate of William Ware Theiss.

The William Ware Theiss Estate Auction

Held on , this  was the largest ever held in regard to garments Theiss had designed for , most of which he apparently retained possession of after the series wrapped. Proceeds of the auction were to go, according to his will, to "Project Angel Food", a LA-based non-profit agency that served hundreds of meals on a daily basis to those challenged by HIV-AIDS, cancer and other diseases. Though most of the 144 lots, of which #805 – #918 were Star Trek related, have since then attained legendary status, some of the more remarkable were:
 Lot 810: William Shatner's Tunic from several Star Trek episodes Estimate: $3,000 – $5,000; Highest bid: $18,400
 Lot 834: Leonard Nimoy's Tunic from  Estimate: $5,000 – $7,000; Highest bid: $8,625
 Lot 835: Nichelle Nichols' Costume from the Star Trek episode "Mirror, Mirror" Estimate: $2,000 – $4,000; Highest bid: $6,325
 Lot 850: William Shatner's Tunic from  Estimate: $3,000 – $5,000; Highest bid: $10,925
 Lot 852: DeForest Kelley's Tunic from Star Trek episode "Court Martial" Estimate: $2,000 – $4200; Highest bid: $9,200
 Lot 858: Mark Lenard's Ensemble from  Estimate: $1,000 $; Highest bid: $6,325
 Lot 883: Mark Lenard's Tunic from  Estimate: $1,000 – $2,000; Highest bid: $4,887
 Lot 918: Leslie Parrish's Costume from  Estimate: $700 – $900; Highest bid: $9,200
It is remarkable that some of the more titillating designs of Theiss, for which he has become renowned since, did not do well in this auction. For example lot #866, Diana Ewing's garments featured in , sold for a mere $173,00 (originally estimated at $300 – $500), whereas the garments worn by the Dohlman by France Nuyen in  as lot #843, merely sold for $1,150, having been originally valued at $800 – $1,200

 Christie's  is a renowned worldwide operating auction house, its headquarters based in New York City, with an outstanding reputation. It is currently the world's leading auction house by revenues. Over time, it has held some auctions in which Star Trek items were represented, the 2006 auction, the most remarkable.

Christie's East Entertainment Memorabilia Auction
Held on  and  in New York City, it featured a small amount of Star Trek related lots (lots 726-730) sold in the second part of the auction.  Lots 727-730 were notable as it constituted a complete away mission prop set from The Original Series, with lot 726 as an additional item.

 Film and Television 
Held on  as  in New York City, this was a specialized Hollywood memorabilia auction, consisting of originally 290 listed lots, including several stemming from science fiction franchises, of which 222 were eventually auctioned off. The vast majority of these were commercial period memorabilia, though a portion also stemmed from production sources. Lots 57-71 were Star Trek related. Some lots were interesting as they contained among others collections of negatives and slides of behind-the-scenes imagery, that was usually discarded during the production of the series, but most of the items consisted of said commercial period memorabilia, though three stood out:
: An original twenty-six page typewritten proposal by Gene Roddenberry for the original "Star Trek" television seriesEstimate: $12,000 – $15,000; Highest bid: $19,550 (including buyer's premium)
: An original "tribble" prop from the popular episode Estimate: $1,500 – $2,000; Highest bid: $1,150 (including buyer's premium)

It was rather AMT's second master tooling model. This model came from the possession of Stephen Edward Poe, to whom the model was given by Gene Roddenberry after the production of The Original Series had wrapped. Though slated as such, it has never been used as an on-screen production asset.

 Fred Phillips collection 
During the "Film, Pop and Posters" auction of  as , Christie's auctioned a selection of items, lots 17-26(a), consigned to its Los Angeles auction house from the estate of Fred Phillips. Items that were sold included the original mold for Spock's Vulcan ears (estimate: $20,000) (), as well as a number of other molds and makeup pieces, along with scripts, autographs and other memorabilia. 

 40 Years of Star Trek: The Collection 
Main article: 40 Years of Star Trek: The Collection
From October 3 through 5, 2006, Christie's held a very high-profile auction titled 40 Years of Star Trek: The Collection, in the process becoming one of the most, if not the most, publicized Star Trek auction. The auction of 1,000 lots, all of which were Trek studio models, props, wardrobe, or other memorabilia, took in more than seven million dollars. As it does for most of its auctions, Christie's offered a very collectible print catalog, with photographs and descriptions for every item in the sale.

 Film and Entertainment Memorabilia 
On May 30, 2007, Christie's held another auction, this one titled Film and Entertainment Memorabilia, , in New York. The sale of 288 lots included a wide variety of items from film and entertainment history, including 26 lots (Lots 262-288) containing items from Star Trek, a few of which were re-listed from October 2006's auction. On the date of the sale, exchange rates were approximately as follows: US$1 = £0.51, SFr 1.23, ¥121.52, €0.75. The buyer's premium was changed between the 40 Years auction in October 2006 and May 2007. It was changed to 20% up to 500 thousand dollars, but none of the items in this sale went above that amount. Some selected items:

: Spock's headband from Estimate: $500 – $700; Highest bid: $4,500; Price: $5,400
: Data's bootsEstimate: $200 – $300; Highest bid: $750; Price: $900

 Profiles in History  is a Hollywood memorabilia seller that often includes several rare or unique Star Trek items in its auctions. Profiles prides itself for thoroughly researching their lots and, like Christie's, offers very professional catalogs of all its auctions. Printed copies can be purchased on-line, or PDF versions can be downloaded for free at their official website. The vast majority of their auctions are held under the title "Hollywood Memorabilia Auction", soon shortened to "Hollywood Auction", plus a follow number, as well as on occasion a sub title. Digressions occur when the auction in question is themed, such as an estate sale. Over the years Profile's Hollywood memorabilia auctions have tended to become quite large, typically held over a two-day period. In recent years, the number of lots offered up rarely drop below the one thousand mark.

On 27 October 2010, Syfy channel began airing a tie-in television series, , which showed "Profiles" employees tracking down, appraising and helping auction off film, television and pop culture memorabilia, though the series was cancelled in 2011 after a mere two seasons.

In recent years "Profiles" has come under increasing scrutiny by noted collector Alec Peters, whose blog, "" has since its inception rapidly become a focal point for collectors of Sci-Fi, and in particular Star Trek memorabilia. Main issues Peters had with "Profiles" concerned misrepresentations, accuracy of descriptions and  – or rather their lack thereof – , though "Profiles" in their Conditions of Sale (article 10) explicitly distances themselves from responsibility for accuracy of descriptions, which is a blatant contradiction of their own trumped-up reputation. Items with a Star Trek pedigree are among those regularly misrepresented as "the real deal". One of the more recent examples concerned the offering of a Jem'Hadar battle cruiser model, supposedly used as production asset, in "Profiles"s Hollywood Auction #40 of 12 June 2010. The item was pulled from the auction just prior to the start of the auction without the auction house even bothering to provide a formal explanation, further undermining their credibility.   More examples of unsubstantiated assumptions in the auction descriptions has since then come to light, but in Profile's defense, the sheer volume of offered memorabilia make a thorough provenance research a truly herculean, if not nigh impossible, task, hence their "" provisional clause in their Terms of Sale.

Peters went on to found his own action house, , and has facilitated several major Star Trek auctions himself, starting wit the one in 2010.

 Hollywood: A Collector's Ransom II 

Held on 1 and 2 June 1996, at the Pacific Design Center in Los Angeles, CA, this larger auction consisted of 951 lots of movie and television memorabilia.

 It's A Wrap! Main article: It's A Wrap! sale and auctionIt's A Wrap! is another Hollywood memorabilia seller. In November 2006 CBS announced that It's A Wrap! would conduct a major sale of thousands of Trek items, most of them in eBay auctions. Essentially the follow-up to the earlier October auction, it effectively cleared CBS' inventory of all pre-2009 Star Trek-related items, save for a relatively small collection of choice items retained for exhibition purposes, which are currently under the custody of Paramount Consumer Products when not on tour.

 Julien's Auctions 

 is an auction house, located in Beverly Hills, Los Angeles, California, that was established in the early 2000s, and which has vied to become a competitor of Profiles in History, selling Hollywood memorabilia. In 2010 it held a specialized Star Trek auction.

 Star Trek 

Julien's specialized Star Trek auction was held at the  resort in Las Vegas on . The first part of the auction originated from the personal belongings, not production-related material, of William Shatner, though Lots 1385-1406 were mostly uniforms from the various Star Trek productions. However, the vast majority of the lots were non-production related items (with the exception of the gowns Majel Barrett Roddenberry wore as Lwaxana Troi, Lots 1564-1568), that constituted the second part of the auction, the estate of Majel and Gene Roddenberry. It was however the third part, Lots 1569-1593, that was the more interesting for collectors, as it, for the first time, officially offered up for auction items originating from the 2009 film . Bidders were charged a 25% buyer's premium plus an additional 3% when bidding on-line. Some results of the auction were:

 Hollywood Legends Auction 

A large Hollywood memorabilia auction, in format akin to those held by "Profiles in History", it featured 369 lots originating from a myriad of Hollywood productions, auctioned off in four sessions over a two day period, 5 and 6 April 2013. Only four lots, 117-120, were Star Trek-related, though the last one, Lot 120, was quite the remarkable one, as it concerned the original phaser rifle used in . Considered an iconic piece by the fan community, the rifle was sold at three times the high estimate. Aware of its status and in order to dispel any doubt about its provenance, Julien's had a documentary short commissioned, Julien's Auctions presents: Star Trek, featuring its creator, Reuben Klamer, that was posted on their website and on  in the run-up to the auction.

Hollywood Legends (2018)

 Lot 896: Duty uniform costume prototype made for Patrick Stewart to wear as Captain Jean-Luc Picard in Star Trek: Generations, though ultimately went unused Estimate US$4,000-$6,000; The officially licensed action figure of Picard made by  Playmates for their Star Trek: Generations toyline features an outfit similar to the prototype. 

 Prop Store 

 is a British film and TV prop collection and sales company, operating out of London, UK, and maintaining  a subsidiary branch in Los Angeles, California. Established as "The Propstore of London" in 1998 by founder Stephen Lane, the auction house is conceived along similar lines of its US Profiles in History counterpart.

A difference was that the auction house, as its name already implied, operates an online store where consigners of items that went unsold at their initial auctions could offer up these unsold items for sale if they so desired. This service is still being offered as of late. 

Alec Peters has noted though, that the surcharges the auction house employed for it services were steep, ranging from nearly 50% for EU customers to 25% for US customers on top of the hammer price, but the latter were also charged 20% VAT on top of the total price, included shipping, for those items that were auctioned off in UK venues.  This made participating in the Prop Store auctions a very expensive proposition for auction winners in comparison to the US counterparts.

 Star Trek Live Auction – Star Trek and Star Trek Into Darkness 
Announced on ,  was held in Valencia, California on , featuring 400 lots, including props and costumes, all originating from the production of the first two alternate reality ,  and , and constituted the auction house's first specialized Star Trek auction.

Lot #2 of the auction featured a pair of latex prosthetic Vulcan ears worn by Leonard Nimoy as Spock in .  

 Propworx, Inc. 
 is an auction house specializing in the sale of Hollywood science fiction memorabilia, run by Alec Peters, a noted American memorabilia collector of the genre. Peters founded his company in 2008 when he 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 commissioned to facilitate the sales of other genre franchises such as the Galactica spin-off , , and Stargate. Apart from these, Propworx, also handled the sale of the larger set pieces of the defunct Las Vegas Star Trek: The Experience exhibition in the "STAR TREK: THE EXPERIENCE Warehouse Sale" on 10 April 2010.  This was a prelude to Propworx's first specialized Star Trek auction.

On 22 August 2012 Peters announced the closure of his auction house,  though he kept the official site "live" for the time being until it too went dark around 2018. Nonetheless, Peters continued to organize subsequent memorabilia auctions through online internet auctioneer  afterwards, while concurrently maintaining a dedicated  under the original name.

The official STAR TREK prop and costume auction

Held in Las Vegas on 8 August 2010, this auction featured 450 lots, given in consignment to Propworx from the personal collections of, among others, Doug Drexler, Rick Sternbach, and Mike and Denise Okuda, as well as some leftover items from the "Experience" sale. The auction was accompanied by a deluxe hardcover auction catalog embellished with interviews with the consignors and artwork by Drexler. Some items of note were:
: Spock's Prosthetic Vulcan Ear AppliancesEstimate: $4,000 – $6,000; Highest bid: $3,600 (with buyer's premium)

STAR TREK auction

The second specialized Star Trek auction facilitated by Propworx was held on 4 June 2011. The auction followed the same pattern as the previous one, featuring lots given in consignment by many of the same people as before. The format, however, differed in that instead of holding a live auction, internet auctioneer Live Auctioneers was subcontracted to auction off the lots on line, providing potential buyers the possibility to submit bids from 12 May 2011 until closure on 4 June 2011. The volume offered in this auction was about half of the previous one, 257 lots, not surprisingly perhaps as the consignors were mostly the same. The majority of them were costumes, hand-held props, and smaller production material items. As with the earlier that year held Profile's "Hollywood Auction #44", it was remarkable that a larger portion than usual went unsold and that virtually all items sold within their estimates, indicating that for the time being the largest Star Trek collecting frenzy had passed. Lots of some note were:
: Star Trek TOS matte paintingEstimate: US$8,000 – $12,000; Highest bid: US$12,000 ($14,760 with buyer's premium)
: Star Trek Starship  Study ModelEstimate: US$1,000 – $2,000; Highest bid: US$1,400 ($1,722 with buyer's premium)

: Star Trek: The Next Generation Orbital Graphic TranslightEstimate: US$300 – $400; Highest bid: US$1,400 ($1,722 with buyer's premium, the most undervalued lot)

STAR TREK auction III

The third specialized Star Trek auction facilitated by Propworx was held on 24 March 2012. As with the previous edition, it was an Internet-only auction, again facilitated by Live Auctioneers. It was also the smallest one to date, featuring 91 lots, whereby it was noteworthy that the larger items such as the majority of the costumes and "set" pieces were not production-used items, but rather leftovers from "The Experience" exhibition. The ones that were production-used consisted mainly of props and production art. Virtually all lots sold within their estimates. Some items of note were:
: Star Trek: TMP Class-B Starfleet UniformEstimate: $1,000 – $2,000; Highest bid: $950 ($1,169 with buyer's premium)
