Rumours are swirling that LEGO is set to release a $1,000 (£789.99) set later this year, its most astronomically-priced product ever. While the cheapest sets cost as little as $5 (£4) or so, there are plenty of wow-factor creations by the Danish toymaker that retail for astonishing sums.
From iconic models of the Titanic and Eiffel Tower to coveted Harry Potter and Star Wars projects, read on to discover the most expensive LEGO sets ever, as compiled by collectors' website BrickEconomy and ranked by their original US retail price. Where a set has been retired by LEGO, we've also included its current value, which is often substantially higher than the original price.
All dollar amounts in US dollars.
One of 13 Star Wars-themed sets in this round-up, this Death Star model from Star Wars Episode IV: A New Hope consists of a hefty 3,827 pieces, including 27 minifigures and droids.
Part of the Star Wars Ultimate Collector Series, it was released in 2008 and retired in 2015. Interestingly, the original UK retail price was considerably lower than the US price. Right now, a new and sealed 10188 Death Star is valued at $784 in the US and £619 in the UK, with the set appreciating in value by around 5% a year on average. If you're keen on snapping up a pre-loved set, you can expect to pay an average of $576 in America and £455 in the UK.
The 910002 Studgate Train Station is part of the LEGO Ideas initiative, which lets fans submit ideas for products, giving them a chance to see their creations come to life. Amateur designers lucky enough to get their ideas chosen earn a 1% cut of net sales. Released in 2022 via LEGO-owned marketplace BrickLink, production of the set, which comprises 4,062 pieces with 11 minifigures, was limited to 10,000 units, so it's a highly sought-after item. Like other super-complex and challenging LEGO models, it's targeted at adults rather than under-18s.
The set is currently worth an average of $658 in the US and £520 in the UK if new and sealed, with annual growth anticipated at 13.5% this year and 8.7% in 2026. If you're after a used set, you can expect to pay an average of $630 in America and £497 in the UK.
LEGO's most spectacular and expensive Disney set, the 43222 Disney Castle comprises 4,837 pieces with eight minifigures. Aimed at ages 18 and up due to its complexity, the set was launched in 2023 and is scheduled for retirement by the middle of this year, so if you want to add this enchanting creation to your collection, don't delay.
According to BrickEconomy, the set is expected to appreciate in value by nearly 3% annually after the second year post-retirement. While this isn't terrible, other LEGO sets offer significantly higher returns once discontinued.
The 76252 Batcave – Shadow Box is a striking diorama targeted at adult LEGO enthusiasts. Made up of 3,981 pieces, including seven minifigures, it recreates the secret HQ of the Caped Crusader from the 1992 movie Batman Returns. Released in 2023, it was retired in October 2024.
The set's relatively short lifespan has driven up its value and the 76252 Batcave – Shadow Box is now worth an average of $765 in the US and £604 in the UK if new and sealed, with typical annual growth coming in at around an impressive 30%. Unsurprisingly, used versions in good condition aren't cheap, with an average price of $635 in America and £501 in the UK.
Released in 2022 to mark LEGO's 90th anniversary, the 10305 Lion Knights' Castle is an old-school construction with a retro vibe, nodding to the original castle set from 1984. Comprising 4,514 pieces with 22 minifigures, it's targeted at LEGO's adult aficionados since building the castle is far from simple. The set is part of Icons, a sub-theme of the Creator line. Together with Technic, it offers LEGO's most complex builds, but while Technic focuses on engineering ingenuity, Creator emphasises creative expression.
The set is on backorder on the US LEGO site, but available now from its UK counterpart. It's expected to appreciate in value by close to 5% annually after the second year following its retirement.
Part of the Icons range's Fairground Collection, the 10303 Loop Coaster is made up of 3,756 pieces with 11 minifigures. Standing 36 inches (92cm) tall, it's the third-loftiest set in this round-up. Unlike LEGO's static sets, this beauty has moving parts, including the gravity-driven roller coaster and elevator lift, which can be raised using the Powered Up app.
Launched in 2022 and retired in December 2024, the set is worth an average of $419 in America and £331 in the UK if new and sealed, with an annual appreciation rate of about 7%. A used set, on the other hand, costs between $342 and $387 in the US and between £270 and £306 in the UK.
Another triumph from the Icons range, the 5,876-piece 10299 Real Madrid – Santiago Bernabéu Stadium recreates the Los Blancos' home turf in the Spanish capital, complete with its signature four corner towers. Released in 2022, the adult-orientated set was discontinued in 2023.
Fans of the La Liga football team will clearly pay a premium for the kit, with a new and sealed specimen currently valued at $527 in the US and £416 in the UK. The set is appreciating by an average of 9% per year. Conversely, the price of a used version averages $333 in America and £263 in the UK.
Part of the Star Wars Ultimate Collector Series, the 75309 Republic Gunship is a depiction of a low-altitude repulsorcraft that took part in the Battle of Geonosis from the animated show Star Wars: The Clone Wars. The set consists of 3,292 pieces, including Mace Windu and Clone Commander minifigures.
Launched in 2021 and retired in 2023, the model has a value of $436 in the US and £345 in the UK if new and sealed, with a mean annual appreciation rate of 4%. Used versions in good condition are priced at an average of $350 in America and £276 in the UK.
Staying with Star Wars, the 75290 Mos Eisley Cantina, which is also aimed at adults, was launched in 2020 and discontinued last year.
The Master Builder Series set, which comprises 3,187 pieces with 21 minifigures, currently has an average value of $417 in the US and £330 in the UK if new and sealed, with the figure growing by 15% a year typically. Alternatively, a used Mos Eisley Cantina is priced at $362 in America and £286 in the UK.

Another LEGO kit for ages 18+, the 21323 Grand Piano is made up of 3,662 pieces. An authentic reproduction of a concert grand, this masterpiece of LEGO ingenuity has 25 working keys and connects to the Powered Up app to play music, adding to its awesomeness. It's the most expensive set from the Ideas range.
Having made its grand debut in 2020, the product is still in production and available from the online US and UK LEGO stores, as well as reputable LEGO retailers, at a lower price in some instances. It's expected to appreciate in value by close to 7% annually following the second year of its retirement, which is imminent.
Back to the Star Wars Ultimate Collector Series, the 10221 Super Star Destroyer for ages 16 and up came out in 2011 and was discontinued in 2014. Comprising 3,152 pieces, including five minifigures, it's now valued at a substantial $1,481 in the US and £1,170 in the UK if new and sealed.
In terms of appreciation, the set has grown in value by 5% a year on average. The price of a used version in good condition will set you back an average of $955 if you're in America and £754 in the UK.
Fans of the Wizarding World of Harry Potter are spoilt for choice when it comes to LEGO sets, but need deep pockets to stretch to the most elaborate constructions. Aimed at big kids of 18 and over, 76417 Gringotts Wizarding Bank – Collectors' Edition recreates the Diagon Alley institution and its cavernous underground vault. It features 4,801 pieces with 13 minifigures.
Released in 2023, the set is available from the US and UK LEGO online stores and reputable retailers, but is due to be retired later in 2025, so if you want to get hold of one, you'd better grab it while you can. Once discontinued, the product is expected to appreciate in value by nearly 6% annually after the second year.
The first of three LEGO supercar models in this round-up, 42115 Lamborghini Sián FKP 37 faithfully reproduces the vehicle at 1:8 scale. Developed in close collaboration with Lamborghini, the 3,696-piece set is part of the Technic range, known for its intricate and challenging builds that require advanced LEGO construction skills. Needless to say, the model is targeted at ages 18 and above.
Released in 2020 and still available from the US and UK LEGO sites, the set will soon be retired and its value is expected to appreciate by 3% annually in the second year after its retirement.
LEGO also worked closely with Ferrari to produce the Daytona SP3 in plastic brick form. Like the Lamborghini Sián FKP 37, it's a 1:8 scale model and part of the Technic range.
Consisting of 3,778 pieces, the supercar set was launched in 2022 and is due to be retired over the next few months, so if you've been eyeing it on the LEGO site, now is the time to buy. The expected annual rate of appreciation after the second year following its discontinuation is also 3%.
Released in August 2024, the 42172 McLaren P1 is the latest ultra-premium supercar set from the Technic range. As is the case with LEGO's other high-end supercar collabs, the Danish toymaker worked alongside the vehicle's manufacturer to create the 1:8 model, which comprises 3,893 pieces.
The set for ages 18+ is available now from the US and UK LEGO sites, but its retirement is anticipated by mid-2025. While its predicted lifespan is significantly shorter than that of the Ferrari Daytona SP3 and Lamborghini Sián FKP 37, BrickEconomy expects the model to appreciate annually at the same rate after the second year post-discontinuation.
75978 Diagon Alley is the second most expensive set from LEGO's Harry Potter range. Consisting of 5,544 pieces with 14 minifigures, the construction for ages 16 and above depicts the magical London thoroughfare behind the Leaky Cauldron pub, with five shops, including wand emporium Ollivanders and Florean Fortescue's Ice Cream Parlour.
Launched in 2020, its retirement is expected by the middle of this year. The set is projected to increase in value after the second year by close to 6% annually, double that of the Technic supercars featured in this round-up.
Another tricky-to-put-together set from the Technic range, the 42100 Liebherr R 9800 is a model of the world's biggest hydraulic excavator. Released in 2019 and discontinued in 2021, it comprises 4,108 pieces. Aimed at ages 12 and above, it's the only model in this round-up suitable for younger kids.
A new and sealed set is currently valued at $796 in the US and £629 in the UK. Its annual appreciation rate is around 9% a year. If you're in the market for a used set, you can expect to fork out an average of $484 in America and £382 in the UK.
Released in 2024 as part of the Icons range, the 10333 The Lord of the Rings: Barad-dûr brings to life the infamous dark tower from The Lord of the Rings, complete with an illuminated Eye of Sauron. It's made up of 5,471 pieces, including 10 minifigures, and is targeted at adult LEGO fans.
The set is on backorder on the US LEGO site and is available without a wait from the UK LEGO online store. It's due to be retired next year. In terms of appreciation, the set's value is expected to increase by close to 5% annually after the second year following the end of its run.
Although it isn't the most expensive LEGO Harry Potter set, 71043 Hogwarts Castle is considered the hardest to build and the third most difficult LEGO project overall according to collectors' website Brickfact, though it's aimed at ages 16+ rather than strictly adults. The model of the boarding school for budding wizards consists of 6,020 pieces, including four minifigures, along with 27 microfigures.
The set is on backorder on the US LEGO site but available right now from its UK counterpart. The construction is enjoying a long lifespan, having been released in 2018, but is due for retirement any month now. Once discontinued, it's expected to appreciate in value by around 6% annually after the second year.
The most valuable LEGO set in this round-up, the 10179 Ultimate Collector's Millennium Falcon was released in 2007 and retired in 2010. The Star Wars extravaganza comprises 5,197 pieces with five minifigures. It was marketed at ages 16 and above.
In 2014, a first-edition in an airtight case fetched a staggering $15,000 (£12,091) at a Las Vegas auction, though a regular new and sealed specimen is valued at $1,958 in the US and £1,547 in the UK, with an annual appreciation rate of 7.2% typically. A used version in good condition is mega-pricey too, with an average sale price of $1,000 in America and £790 in the UK.
Yet another LEGO Star Wars creation and the second of three Death Star models in this round-up, the 75159 is actually a re-release of the aforementioned 10188, though it has 213 additional pieces. The model was launched in 2016 and retired in 2020.
The 75159 Death Star has a value of $1,194 in the US and £944 in the UK if new and sealed, with annual growth of around 7%.

Launched in 2021 and discontinued in 2023, the 3,854-piece 42131 Cat D11 Bulldozer from the Technic range is an app-controlled replica of the eponymous bulldozer aimed at LEGO enthusiasts 18 years old and above.
These days, a new and sealed specimen is worth $691 in America and £547 in the UK, with an annual appreciation rate of about 10.2%. Meanwhile, a used set in good condition is typically priced at $419 in the US and £331 in the UK.
The 75397 Jabba's Sail Barge replicates the Hutt crime lord's luxurious mode of transport from the Return of the Jedi. This particular Star Wars Ultimate Collector Series set for grown-ups was released last year and comprises 3,943 pieces, including 11 minifigures.

One of two sets in this round-up from the Marvel Super Heroes range, the 76269 Avengers Tower came out in 2023. With a height of 35 inches (90cm), it's among the tallest LEGO sets ever made and the fourth tallest in this showcase. All in all, the adult-orientated kit has 5,201 pieces with a generous 31 minifigures, the most of any of the sets featured here.
The set is available without a wait from both the US and UK LEGO sites but is due to bite the dust sometime during the next few months. In terms of appreciation, its value is expected to grow by close to 5% annually after the second year following the end of its run.
The priciest of the LEGO sets themed around The Lord of The Rings, this model of the Elven idyll Rivendell is also the largest, with 6,167 pieces, including 15 minifigures.
Targeted at ages 18 and up, the set was released in 2023 and is slated for retirement by the middle of this year, so if it's on your wishlist, you'd better get cracking. Once it's been axed, the set is expected to appreciate in value by close to 5%, but only after the second year following its discontinuation.
The 76405 Hogwarts Express Collectors' Edition is the most expensive Harry Potter LEGO set to date, but it isn't the largest, with the 71043 Hogwarts Castle holding that distinction. That said, the model of the locomotive that runs between London King's Cross Station Platform 9¾ and Hogsmeade Station is by no means modest, with 5,129 pieces, including 20 minifigures.
Launched in 2022 and retired last November, the adult-orientated set is worth $625 in the US and £493 in the UK when new and sealed. If you're looking for a used version, you can expect to pay an average of $543 in America and £429 in the UK.

Prices for a secondhand specimen average out at $613 in the US and £484 in the UK.

The depiction of the Paris landmark is also the tallest LEGO set ever created, soaring to a height of 58 inches (128cm).

The most expensive set from the Creator Icons series, the 10294 Titanic is a remarkably detailed 1:2000 scale model of the doomed ocean liner. It debuted in 2021. Aimed at ages 18 and up, the set consists of 9,090 pieces, which makes it the second-biggest LEGO model in this round-up and the third-largest ever created.
Again, the kit is on backorder on the US LEGO site but available now from its UK counterpart. It's due to be discontinued sometime during the next few months. Once retired, the product is predicted to appreciate in value by close to 5% annually after the second year.
The 42146 Liebherr LR 13000 recreates the world's most powerful crane in plastic brick form. The most expensive Technic build, it's the second-tallest set this round-up, with a height of 39 inches (99cm), and the second most challenging LEGO set overall to construct, as per Brickfact.
Launched in 2023, the 2,883-piece set for adult LEGO enthusiasts is currently on backorder on the US LEGO site but available without a wait on the UK version, though its retirement is right around the corner. Following the kit's discontinuation, it's projected to appreciate in value by close to 3% after the second year.
The 75252 Imperial Star Destroyer from the Star Wars Ultimate Collector Series consists of 4,784 pieces, including two minifigures.
The set for ages 16 and over was released in 2019 and retired at the end of 2022.

Aimed at adults, the Star Wars Ultimate Collector Series model of the Empire's most formidable combat walker was launched in 2021 and retired last November. Right now, it's worth $974 in America and £769 in the UK if new and sealed, and has an annual appreciation rate of around 6%. A used set in good condition isn't all that more affordable, coming in at an average of $808 in the US and £639 in the UK.
Sharing the accolade with the 75313 AT-AT as the most expensive LEGO product in existence, the 75192 Millennium Falcon solely held the title when it launched in 2017, four years before the former's release at the same price.
With 7,541 pieces, including eight minifigures, the 75192 Millennium Falcon was the largest LEGO set upon its release. The Star Wars Ultimate Collector Series kit for ages 16+ sold out almost immediately, but LEGO has since replenished stock and it's currently available to buy from both the US and UK LEGO sites, making it the priciest set still in production. Nonetheless, it's due to be retired by mid-2025. Once discontinued, the set is expected to appreciate in value by close to 5% annually after the second year.

What is certain is that the product will boast an exceptional level of detail and scale, making it a must-have for serious LEGO enthusiasts and Star Wars obsessives alike.
