The best way to start a LEGO Star Wars collection in 2026 is the same as ever: one Ultimate Collector Series centerpiece you love, then smaller builds around it. What is different this year is the calendar. Four current UCS sets, the Millennium Falcon among them, carry an expected exit date of December 31, 2026 in our catalog, while the newest UCS sets are expected to stay into 2027 and 2028. This guide covers which is which, where helmets and the display-scale starships fit, what retired UCS sets are worth in our market data, and how to display and look after big builds. Recommendations are research based, from our catalog and LEGO's own set descriptions.
The LEGO Star Wars collector lines in 2026
Ultimate Collector Series (UCS) is the display line for adults: large, screen-accurate models, most with a stand and an information plaque. Current UCS sets are marked 18+, apart from the 2017 Millennium Falcon at 16+. It is where every big Star Wars centerpiece comes from.
Helmet Collection sets are brick-built replicas of character helmets on a stand with a nameplate. They are the cheapest way into display collecting and line up well on a single shelf.
Starship Collection models are smaller display builds of famous ships on angled stands, a way to own the silhouette without the footprint of a UCS model. Our UCS vs midi-scale guide compares the pairs that exist at both scales.
Two lines collectors still ask about are no longer on sale. The Master Builder Series had two sets, Betrayal at Cloud City and the Mos Eisley Cantina, and both have retired; see UCS vs Master Builder Series. The Diorama Collection, from the Death Star Trench Run to the Mos Espa Podrace, has retired too; our diorama comparison covers them.
UCS sets leaving on December 31, 2026
Millennium FalconThese four carry an expected exit date of December 31, 2026 in our catalog, which makes this holiday season the last one in which LEGO itself sells them. Piece counts and status on each card come from our catalog.
The 2017 UCS Millennium Falcon, one of the biggest LEGO models ever made, with interchangeable crews and parts for both the classic and sequel trilogy looks. The single set most collectors want on the shelf.
The Clone Wars Venator-Class Republic Attack Cruiser, over 43 inches long, with its red stripes, command bridge and a hangar holding a small Republic Gunship.
The TIE Interceptor, a redesign of a ship from the very first UCS wave in 2000, and one of the most compact UCS builds for a desk or shelf.
Jabba's Sail Barge from Return of the Jedi, with textile sails, a lift-off top deck and fold-down sides that open onto a detailed interior.
UCS sets expected to stay into 2027 and 2028
Death StarIf none of the four above is the ship you want, there is no rush. These current UCS sets have expected exit dates in 2027 or 2028 in our catalog, and the newest, the Executor, has none yet.
The UCS Death Star, which LEGO describes as the biggest LEGO Star Wars set at launch. It builds on a compact foundation, so it needs less shelf width than its size suggests.
Jango Fett's Firespray-Class Starship from Attack of the Clones, over 17 inches long, with a detailed cockpit.
The AT-ST Walker from the battle of Endor, with a top hatch that opens onto a two-person cockpit. A good first UCS set for a small space.
The Mandalorian's N-1 Starfighter, the 2026 addition to the line, built with special silver-colored bricks.
The Executor Super Star Destroyer, released in October 2026 and the longest LEGO Star Wars model so far. Check the card for current details while our catalog fills in its listing.

Which Millennium Falcon to collect
Millennium FalconThe 2019 Millennium Falcon (75257) that many guides still recommend as the affordable option has retired; our catalog lists its expected exit at the end of 2024. In 2026 there are three current Falcons, for three different buyers:
The Starship Collection Millennium Falcon, an 18+ display model of the A New Hope Falcon on a stand that shows it at an angle, as if in flight. The space-saving way to own it.
The SMART Play compatible Millennium Falcon for children aged 9 and up, with stud shooters and a lift-off top for play inside. A play set, not a display model.
The third is the UCS Falcon above. Our Millennium Falcon comparison sets them side by side.
Helmets: the entry point to display collecting
The Mandalorian HelmetHelmets give a collection a consistent look at a fraction of the space. Three current helmets share the December 31, 2026 expected exit date; two are expected to stay into 2027.
The Mandalorian Helmet, with drum-lacquered elements for the sheen of beskar armor.
The AT-AT Driver Helmet from The Empire Strikes Back.
The Kylo Ren Helmet, released for the tenth anniversary of The Force Awakens.
The Jango Fett Helmet, with an adjustable rangefinder antenna.
The Imperial Remnant AT-RT Driver Helmet from The Mandalorian and Grogu, the newest helmet in the line.
Our Star Wars helmets comparison covers the line in more depth.
Collecting for value: what our data shows
Buy LEGO Star Wars to display it; treat any rise in value as a bonus. Our market data supports that order of priorities. We looked at every retired UCS set with a current market value for a new, sealed copy in our data, checked between December 2025 and September 2026, against its US list price. There are 12, and all 12 are worth more than list. The median is about 2.4 times list, but the spread is wide and the age of the set explains most of it:
| Retired UCS set | Released | Market value as a multiple of US list price |
|---|---|---|
| Death Star II | 2005 | 15.5 times |
| Motorized Walking AT-AT | 2007 | 4.6 times |
| Death Star | 2008 | 2.5 times |
| Tantive IV | 2009 | 2.7 times |
| Imperial Shuttle | 2010 | 5.4 times |
| R2-D2 | 2012 | 1.1 times |
| Red Five X-Wing Starfighter | 2013 | 1.3 times |
| Ewok Village | 2013 | 3.5 times |
| Snowspeeder | 2017 | 2.3 times |
| Imperial Star Destroyer | 2019 | 1.8 times |
| Republic Gunship | 2021 | 1.3 times |
| AT-AT | 2021 | 1.4 times |
Three things to take from it. The three most recent retirees are worth roughly 1.3 to 1.8 times list, which is a modest gain once selling fees and the cost of shipping a large box come out. The big multiples took more than a decade. And these are estimates of what a new, sealed copy sells for, so a built set or a damaged box is worth less. Our LEGO investment guide covers buying, storing and selling in detail, and LEGO Sets Retiring in 2026 lists every expected exit date.
Some collectors buy two copies of a UCS set, one to build and one to keep sealed. That doubles the outlay and only pays off if the sealed copy rises enough to cover the fees of selling it, so it suits sets you would happily keep anyway.
When to buy
LEGO's own Star Wars promotions cluster around May 4, Star Wars Day, and its biggest sale events come around Black Friday, with LEGO Insiders getting early access and members' offers. Other retailers set their own sale prices, so compare against the price LEGO itself charges rather than a crossed-out price. For a set with a December 31, 2026 exit date, a fair price before the holidays beats waiting for a better one that may not come.
Building a UCS set
- Clear a large table with room for the instructions, the open bags and the growing model.
- Work bag by bag. The numbered bags are natural stopping points, and opening one bag at a time keeps the pieces you need in view.
- Sort each bag into small trays by color and type before you start that section.
- Read the overview image first on a big step, then build its subassemblies one at a time.
- Keep the brick separator close. When something will not line up, step back a few pages; a single missing small piece is the usual cause.
Displaying a Star Wars collection
Measure before you buy. UCS ships are long and deep, and the bigger ones need a wide, deep shelf or a cabinet top rated for their weight. A single centerpiece looks best at about eye level with soft light; a group of sets reads better when it is themed, such as Rebels against the Empire or one trilogy per shelf. Glass-fronted cabinets keep dust off medium sets, and helmets line up well along one shelf. Our guides to displaying a LEGO collection and DIY display shelves from IKEA furniture go further.
Care: dust, sunlight and moving
- Dust: a case or cabinet is the best defense. On open shelves, use a soft, dry brush and low-pressure compressed air; avoid wet cloths and feather dusters. More in Protecting LEGO from Dust.
- Sunlight: keep sets out of direct sun, which yellows white and light grey bricks over time. A stable, moderate room is better than an attic or a garage.
- Moving: photograph the model first, remove loose parts such as antennas, weapons and minifigures, split it at its natural sections where the instructions allow, and pack each part with padding in a labeled box.
