(written from a Production point of view)
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 Star Trek: Enterprise, 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
Butterfield & Butterfield 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 eBay. In 1993 the auction house was commissioned to sell off the estate of William Ware Theiss.
The William Ware Theiss Estate Auction
Held on 12 December 1993, this auction was the largest ever held in regard to garments Theiss had designed for Star Trek: The Original Series, 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 TOS: "Mirror, Mirror"
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 TOS: "Court Martial"
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 TOS: "Journey to Babel"
Estimate: $1,000 $; Highest bid: $6,325
- Lot 883: Mark Lenard's Tunic from TOS: "Balance of Terror"
Estimate: $1,000 – $2,000; Highest bid: $4,887
- Lot 918: Leslie Parrish's Costume from TOS: "Who Mourns for Adonais?"
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 TOS: "The Cloud Minders", sold for a mere $173,00 (originally estimated at $300 – $500), whereas the garments worn by the Dohlman by France Nuyen in TOS: "Elaan of Troyius" 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 20 June 1996 and 25 June 1996 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. 
- Lot 726: Star Trek V: The Final Frontier, autographed cast picture (1699 out of 2500)
Estimate: $600 – $800; Highest bid: $1,265
- Lot 727: Hand phaser
Estimate: $2,000 – $2,500; Highest bid: $3,680

Estimate: $5,000 – $7,000; Highest bid: $8,050
Film and Television
Held on 18 June 1998 as Sale 8115 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:
- Lot 61: An original twenty-six page typewritten proposal by Gene Roddenberry for the original "Star Trek" television series
Estimate: $12,000 – $15,000; Highest bid: $19,550 (including buyer's premium)
- Lot 70: An original "tribble" prop from the popular episode "The Trouble with Tribbles"
Estimate: $1,500 – $2,000; Highest bid: $1,150 (including buyer's premium)
- Lot 71: The original model of the "Klingon" "Bird of Prey" [sic.] warship used in the "Star Trek" television series
Estimate: $15,000 – $20,000; Highest bid: $11,500 (including buyer's premium); The D7 class model not only misidentified, it was also misrepresented as a screen-used model, the actual one being in the possession of the National Air and Space Museum. 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 15 November 2000 as Sale 9442, 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) (Star Trek Monthly issue 74), 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, Sale 1854, 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:
- Lot 272: Spock's headband from Star Trek IV: The Voyage Home
Estimate: $500 – $700; Highest bid: $4,500; Price: $5,400
- 273 : Data's boots

Estimate: $8,000 – $12,000; Highest bid: $18,000; Price: $21,600
Profiles in History
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, Hollywood Treasure, 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, "The Star Trek Prop, Costume & Auction 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 provenance – 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 "caveat emptor" provisional clause in their Terms of Sale.
Peters went on to found his own action house, Propworx, Inc., 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. Of these lots 748-778, auctioned off in the second part of the auction, were Star Trek related. Noteworthy was that a relative large proportion originated from Star Trek: The Original Series.  Some of the more remarkable lots were:
- Lot 748: Star Trek hand laser from the original pilot episode "The Cage"
Estimate: $6,500-$7,500; Highest bid: $3,998.40
- Lot 751: Star Trek tricorder

Estimate: $10,000-$15,000: Highest bid: $15,680
Hollywood Auction 10: The Star Trek Auction
On 12 December 2001, Profiles held an auction at the Hollywood Entertainment Museum, featuring many items from the personal collections of Matt Jefferies, including his complete collection of original design sketches he produced for Star Trek: The Original Series, his brother John, Herb Solow, and Robert Justman. The proceeds from the sale of the Jefferies items went to the charitable organization "Motion Picture & Television Fund". All the handheld props came with certificates of authenticity from former set decorator John Dwyer.
The auction featured in total 337 lots, the vast majority Star Trek related, constituting the very first specialized Star Trek auction, even though lots 307-335 originated from various other science fiction franchises. Of the Star Trek lots, most were The Original Series related with lots 258-306 related to various later Star Trek productions. Noteworthy is, that interest in collecting Star Trek memorabilia had jumped considerably by that time as many items sold well beyond their high estimates. Some results:
- Lot 221: "Star Trek" prop Tri-corder
Estimate: US$12,000-$15,000; Highest bid: US$45,000
- Lot 224: "Star Trek" Type-1 Phaser
Estimate: US$3,000-$5,000; Highest bid: US$15,000
- Lot 225: "Star Trek" Type-1 Phaser

Estimate: US$3,000-$5,000; Highest bid: US$45,000
The catalog also came in a limited edition of 100 numbered copies signed by Matt Jefferies, Bob Justman, and Herb Solow. Noteworthy was, that the auction was also open to Internet bidders through eBay, one of the very first Profiles auctions to do so, for a few days prior to the final auction. Many lots of this auction, including the small, screen-used Enterprise model, were acquired by Microsoft's co-founder and "Trekkie" Paul Allen for his Science Fiction Museum and Hall of Fame in Seattle, now known as the Museum of Pop Culture (MoPop).  
The Bob Justman Star Trek Auction
- Lot 175: Command Chair and platform from the USS Enterprise
Estimate: $100,000-$150,000; Highest bid: $265,000  and acquired by the aforementioned Paul Allen.

An auction featuring in total 341 items from several genre productions such as Aliens, Battlestar Galactica, the original Batman television series, of which 225 items were from the Star Trek franchise (many from the personal collections of Rick Sternbach and John Eaves), was held by Profiles on April 26, 2003 as The Ultimate Sci-Fi Auction.  Some of the more notable items were:

- Lot 307: USS Enterprise-D special effects four-foot filming model for Star Trek: The Next Generation
Estimate: $20,000 – $30,000; Highest bid: $20,000 (Note: this was a misrepresentation; it was not the actual filming model, but rather a display piece for a Far Eastern "Planet Hollywood" restaurant)
Hollywood Auction 18
Held on 31 March 2004 in Beverly Hills, California, this large auction constituted of 538 lots of memorabilia from Hollywood television and motion picture productions, many of them from the science fiction genre. Lots 200-264 were Star Trek related. Noteworthy was that a significant number of those originated from the personal collection of Rick Sternbach and from previous auctions, notably the "The Star Trek Auction" of 2001. Some of the more interesting items were:
- Lot 201: Spearhead from She, later used in the Star trek episode "The Cage"

Though slated as such, it has never been used as an on-screen production asset. This is the same model as auctioned off in the aforementioned Christie's Film and Television auction.
- Lot 212: Gorn mask, tunic, and gloves from the Star Trek episode "Arena"
Estimate: $60,000 – $80,000 (from the 2003 "The Ultimate Sci-Fi Auction")
Hollywood Auction 22
Held on 29 July 2005 in Beverly Hills, California, this outing in the Hollywood Auction series consisted of 645 lots, stemming from various productions, including several science fiction franchises such as Star Wars and Battlestar Galactica. Of these items, lots 444-484, 41 in total, were Star Trek related.

The deal was closed before auction start, and was therefore not featured in the auction itself.
- Lot 319: A complete Gorn head mask
Estimate: $20,000 – $30,000; Highest bid: $27,500. In the 2014 Christmas episode of The Graham Norton Show, famed comedy actor Ben Stiller was a guest, and it was there that he outed himself as a huge Original Series Trekkie, disclosing it was he who had bought the Gorn mask, among others.

Hollywood Auction 43
Held on 17 and 18 December 2010, this auction was the second large memorabilia auction held that year, boasting 1,345 lots from again various genres produced for television and movies. Science Fiction, Fantasy, and Horror genres were particularly well represented in this auction as a large number of items from several franchises like the Alien, Stargate, Terminator, and other franchises were auctioned off. Star Trek was this time less well represented as only Lots 992–1037 were related to the franchise. Some items of note were:

Icons of Hollywood Auction

Two lots, 1085 and 1086, purportedly being screen-used admiral tunics worn by William Shatner, were pulled from the auction as provenance and authenticity proved inaccurate,  again through scrutiny by Alec Peters.  Noteworthy was that some of The Original Series items demanded and fetched very high prices, whereas other items went unsold.  The more notable items were:

It's A Wrap!
- Main article: It's A Wrap! sale and auction
It'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 presently under the custody of CBS 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.
Julien's specialized Star Trek auction was held at the Planet Hollywood resort in Las Vegas on 27 June 2010. 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 Star Trek. Bidders were charged a 25% buyer's premium plus an additional 3% when bidding on-line. Some results of the auction were: 
- Lot 1388: Star Trek Nemesis Display Panel

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 "Where No Man Has Gone Before". 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 YouTube in the run-up to the auction. 
- Lot 117: STAR WARS AND STAR TREK IMAGE ARCHIVE, An archive of approximately 241 images from eight films in the Star Wars and Star Trek franchises.

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 26 October 2017, this auction was held in Valencia, California on 2 December 2017, featuring 400 lots, including props and costumes, all originating from the production of the first two alternate reality Star Trek films, Star Trek and Star Trek Into Darkness, and constituted the auction house's first specialized Star Trek auction.

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 Caprica, Iron Man, 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.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
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 Live Auctioneers afterwards, while concurrently maintaining a dedicated Facebook page 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:

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:
- Lot 1: Star Trek TOS matte painting
Estimate: US$8,000 – $12,000; Highest bid: US$12,000 ($14,760 with buyer's premium)
- Lot 45: Star Trek Starship USS Excelsior Study Model
Estimate: US$1,000 – $2,000; Highest bid: US$1,400 ($1,722 with buyer's premium)
- Lot 52: Star Trek: First Contact Phaser Rifle
Estimate: US$3,000 – $4,000; Highest bid US$4,000 ($4,920 with buyer's premium)

- Lot 104: Star Trek: The Next Generation Orbital Graphic Translight
Estimate: 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:
- Lot 5: Star Trek: TMP Class-B Starfleet Uniform
Estimate: $1,000 – $2,000; Highest bid: $950 ($1,169 with buyer's premium)
