You might never have thought of a LEGO set as an investment, but at one time, collectible LEGO sets were outperforming gold and other precious metals in terms of appreciation. Though no more recent studies have been done on the subject, there’s still a massive secondary market for the world’s rarest and most intricate sets, especially those that are in mint condition.

Top 7 Most Expensive Lego Sets in the World

Because prices for these sets on secondary markets fluctuate constantly, this article focuses on the highest-priced model sets at the time of release.

1 (Tie). Diagon Alley #75978 – $399.99

Fans of the Harry Potter series will love this magical set, packed with details from the movies and including minifigures of their favorite characters. The scenes depicted include Ollivander’s Wand Shop, Weasley’s Wizard Wheezes, Flourish & Blotts and more.

The set can be built four different ways, and the whole thing is compatible with the LEGO Modular Buildings series. Diagon Alley is temporarily out of stock from official LEGO stores, where it’s still listed at its original price. The set fetches nearly $1,000 on Amazon.

1 (Tie). Hogwarts Castle #71043 – $399.99

Another Harry Potter favorite, this 6,020-piece set is designed to “make the magic come alive” with tons of detail inspired by the hit films.

More than just scenes, this set includes 27 microfigures of your favorite characters, four legendary Hogwarts wizard minifigures and a buildable Hungarian Horntail dragon. While it has, in the past, been hard to find, Hogwarts Castle is currently available on the LEGO site and sells at its regular retail price on Amazon.

1 (Tie). Ferrari Daytona SP3 #42143 – $399.99

Authenticity was a priority in the creation of the Ferrari Daytona SP3 set. The 1:8-scale model is geared toward serious car buffs, with a buildable V12 engine with moving pistons, a working eight-speed sequential gearbox with paddle shifter and a driver seat console. With 3,778 pieces, it’s one of LEGO’s largest Technic vehicle sets ever produced.

This LEGO set is still in production and is available on the LEGO website.

2 (Tie). Liebherr R 9800 Excavator #42100 – $449.99

The Liebherr R 9800 Excavator set has a CONTROL+ app that you can use as a remote for select models. This particular Technic set is powered by seven motors that allow for precise movements via intuitive controls from a compatible smart device.

For even more fun after the challenging construction, the CONTROL+ app includes a challenges and achievements screen where you can unlock reward badges by completing specific tasks.

This set has been retired, so it’s no longer available on the LEGO website. However, you can purchase it elsewhere, at a premium — it’s currently listed at $739.99 on Amazon.

2 (Tie). Cat D11 Bulldozer #42131 – $449.99

The Cat D11 Bulldozer is another app-controlled set with real-to-life features like adjustable tracks and moving blade, ripper and ladder you control via the app. The model has over 3,800 pieces and measures over 22 inches. Once you’ve got it built, use the CONTROL+ app to drive and operate your creation.

This set is currently available on the LEGO website. Amazon retailers have it listed for prices ranging from $475 to $670.

3. Death Star (Ultimate Collector’s Series) #75159 – $499.99

The 2016 edition of the Death Star is a marvelous memorabilia set, with 23 minifigures, movable lasers, scenes from the original movie and a planet destroyer to top it all off. This challenging LEGO set also includes more than 4,000 pieces, so it’s sure to keep you busy for a while.

Unfortunately, this set has already been retired, so to get your hands on one, you’ll have to turn to the resale market, where prices on of this collectible have increased monumentally — north of $1,000 for new-in-box sets.

4. Colosseum #10276 – $549.99

This colossal Creator Expert set is the largest to date in terms of pieces, with more than 9,000 reasons to watch where you step. The model is faithfully recreated, even down to the surviving archways, original paving stones and olive trees. The Colosseum is still readily available on Lego.com for the original price.

5. Titanic #10294 – $629.99

The 54-inch Titanic might be the largest model produced by a LEGO set. Designed with authentic details, Titanic has a buildable bridge, promenade deck and pool. It’s constructed in three sections to highlight cross sections of the ship’s interior, including the staircase, boiler room and smoking lounge. 

This 4,095-piece set is for adults age 18 and up. It’s temporarily out of stock on the LEGO website, but a number of Amazon merchants have it listed for $950 to $1,099.

6. Imperial Star Destroyer (Ultimate Collector Series) #75252 – $699.99

Nearly 4,800 pieces and a finished model measuring more than 3 feet long and 2 feet wide, this is one of the larger LEGO sets to date, and the build is no easy task. This model was created to display all of the details shown in the opening scene of “Star Wars: A New Hope.”

The set is still available on the LEGO site, but collectors expect it to appreciate once it retires in the coming years.

7. Millennium Falcon (Ultimate Collector Series) #75192 – $799.99

With more than 7,500 pieces, the UCS Millenium Falcon is easily among the most intricate LEGO models ever made. Released in early 2018, it includes minifigures of crew members from numerous films, including Han and TFA Han Solo, Rey, Finn, BB8, Chewbacca, Princess Leia and C-3PO.

Despite the fact that it hasn’t yet been retired, it can be hard to find, although as of this writing, it’s available on Amazon at a $5 discount and is in stock on the LEGO site. Additionally, you can find several listings on eBay for more than $1,000.

Good Advice

Before you go out and buy every set you can find, remember that they don’t all appreciate over time. That, and there’s no true consensus as to what a set is worth — only what a buyer is willing to pay.

Some of the sets on this list have appreciated steadily, and this usually happens after a set has been retired. Your best bet is to either buy the sets you’d like to build along with an extra copy to keep in mint condition or spend time learning what makes a good LEGO investment set.
