The number one most expensive Lego set ever released is the Lego Ultimate Collector Series Star Wars AT-AT. It is a recreation of the gigantic war machine first shown in The Empire Strikes Back. The famous scene has the AT-ATs attacking the rebels on Hoth when Luke Skywalker and a band of rebel fighters managed to take down the fleet.

Lego released many different variations of the AT-AT over the years. However, most of them were toy sets designed with kids in mind. Those sets were all relatively small and lacked the detail that this massive build packs in.

Speaking of size, the AT-AT stands over two feet tall and deep, plus ten inches wide. The scale of the build is really staggering. However, the scale of the build is also one of its biggest problems. The AT-AT isn’t a practical machine, and it is strictly science fiction. There is entirely too much weight very high up, which makes it difficult to stand. Luckily, the legs have gears in them to better support the structure while also allowing it to pose.

The nice thing about the Lego AT-AT is just how much detail is on the inside. There is even a bridge inside of the head portion with room for minifigures. You do get nine minifigures, but five of them are Snowtroopers. The best feature has the be the rope and winch that Luke uses to climb up the AT-AT to destroy it. However, what puts the AT-AT in first place is its staggering price tag of $849 for the 6,785-piece set.

The runner-up for the most expensive Lego set is the Star Wars Ultimate Collector Series Millennium Falcon. This is one is the most notorious ships in the galaxy. After all, this is the ship that made the Kessel Run in less than 12 parsecs. Few things have stayed the same in the nearly fifty-year history of Star Wars. However, the Millenium Falcon still remains a staple of the franchise.

In fact, one of the best features of the Lego Millennium Falcon is that it has the rectenna from the original trilogy. You can also remove it to resemble the ship’s later appearances in the sequel trilogy. It even comes with the rectangular dish that replaced the original after it broke off. The set also includes two sets of minifigures. It comes with Episode IV, V, and VI minifigures of Han Solo, Chewbacca, Princess Leia, and C-3PO, plus Episode VII and VIII minifigures of Han Solo, Rey, and Finn.

There are a number of other small details found throughout the ship. Some of the best examples are inside, which is easily accessible via removable access panels. One example is the holo chessboard with seats around it. Even the pathways are round, just like in the movies. Of course, the best-known part of the ship is the cockpit, which has more than enough room for Han and Chewbacca, plus a few passengers. Altogether, the completed Millennium Falcon measures 33 inches long by 23 inches wide and eight inches tall.

Although the Millennium Falcon is the runner-up to the most expensive Lego set, it is actually tied for first place with the AT-AT when it comes to price. Both sets have an MSRP of $849. However, accounting for the price per piece, the Millennium Falcon comes in at number two since it is a better value with 7,541 pieces.

The Star Wars Ultimate Collector Series Imperial Star Destroyer continues the trend of expensive Lego sets based on Star Wars films. Unlike the previous two Lego Star Wars sets, the Imperial Star Destroyer is no longer available for sale. It came out in 2019 and was retired in 2022. Despite the short window to purchase, it was one of the most popular of the Ultimate Collector Series sets.

There are so many iconic ships from the Star Wars franchise, but the massive Imperial Star Destroyers are some of the most memorable thanks to their size. Therefore, Lego had to make a model that really captured how large the ships are. They certainly did, as the ship measures 43 inches long by 26 inches wide and 14 inches high.

However, one of the biggest challenges is that Star Destroyers are relatively bare on the top compared to other ships like the Millennium Falcon. The outer shell is also a standard gray color, which can get a bit boring. Even so, Lego managed to pack in a fair bit of detail, particularly on the back and inside of the ship. Looking from the side, you can actually see a lot of small details between the top and bottom.

Surprisingly, the ship only comes with two minifigures, an Imperial officer and a crewmember. The set had an MSRP of $699, which is over $100 cheaper than the Millennium Falcon and AT-AT. That is still very expensive, especially considering that it only comes with 4,784 pieces. Since it is now retired, the price has increased significantly.

The Lego Titanic is perfect for nautical fans and it is the fourth most expensive Lego set on our list. As its name implies, the set is based on the infamous oceanliner that hit an iceberg on its maiden voyage. In recent years, Lego has made a number of sets based on iconic places or objects, such as the Roman Colosseum.

There are so many tales of the Titanic still being told that it is hard to believe it sank over one-hundred years ago. While there are plenty of historical references, photos and videos of the ship are few and far between. The reason this is important is that Lego sets are often packed with intricate details, and the Titanic is certainly no exception.

Lego took things a step further by even recreating the engine rooms from the ship. From the outside, the Titanic looks phenomenal, but it actually splits into pieces to allow you to get a better view of the interior. Staterooms are individually recreated, including multiple floors. You can even remove the engines from the lower ship for a closer inspection.

Unfortunately, the Titanic is a very expensive set, retailing at $679. However, it comes with an astonishing 9,090 pieces, making it the second-largest Lego set. Even more remarkable is its size at 54 inches long by 18 inches high and seven inches deep. This slender design makes it easy to fit on a shelf for display, and you will definitely want to display it, as it is arguably the best-looking Lego set ever made.

World Travelers will love the Lego Eiffel Tower set. Not only is this one of the most expensive Lego sets ever made, but it is also the newest one on our list. The Eiffel Tower came out back in November of 2022 and it is currently still in production.

Inspired by the iconic tower in Paris, France, Lego designers did an impeccable job recreating this stunning metal tower out of plastic bricks. To capture the immense scale, Lego had to create their largest build ever, standing 59 inches tall by 23 inches square. The Eiffel Tower Lego set has a staggering 10,001 pieces. It is the second-largest Lego set, coming in behind the Lego World Map which has 11,695 pieces.

The Eiffel Tower is a little tall to place on a table to display, but putting it on the ground also doesn’t do it justice. Unlike the Titanic, which nicely fits on a shelf, the Eiffel Tower is hard to display. Fortunately, you do get more than just a plain metal frame, as there is a small park underneath. You can also spot the observation platform and guest elevators. The Eiffel Tower may be massive, but it has a relatively low price per piece, with an MSRP of $629. If this is out of your price range, Lego also offers a smaller version in their Architecture Series for much less.

How to Pick the Most Expensive Lego Set: Step by Step

When picking out an expensive Lego set, there are four main considerations for most buyers. 

  • Theme
  • Number of pieces
  • Price
  • Size

Let’s review each of these criteria in more detail.


The first thing you need to look at is the theme. For instance, buying the most expensive Lego set ever made isn’t a good idea if you aren’t interested in Star Wars. In contrast, if you are a major Star Wars fan, then you will definitely want to get sets like the Millennium Falcon. It is important that you buy sets that interest you rather than trying to simply buy the most expensive set.

Number of Pieces

Next, you should always look at how many pieces are in a given set. Doing so will help you gauge the set’s value and provide an estimate of how long it will take to assemble. All of the sets mentioned above are some of Lego’s largest, so they will take days, if not weeks, of work. The number of pieces can also give you an idea of the intended age range. In this case, all of the sets mentioned are for adults.


The number of pieces by itself can actually be a bit misleading because not all pieces are the same size. That is why you should also look at the physical size of the complete model. This is critical to ensuring you have somewhere to keep it. Some models are slender, so they will fit on a shelf, like the Titanic. But others are very round and may be difficult to display, like the Millennium Falcon.


Finally, you should always look at the price of a Lego set. While we’ve covered the five most expensive sets, there is a pretty dramatic difference in those prices. Generally speaking, some Lego sets start under $10, while others go beyond $800. You must always ensure that the set you purchase fits into your budget. You should also consider whether it is a good value based on the price per piece.

What to Know Before Buying an Expensive Lego Set

Lego products are some of the most expensive building toys you can buy. While there are certainly much more expensive hobbies, building with Lego may have the most sticker shock. The reason is that people often associate Lego sets with kids’ toys and therefore assume they will be cheap. However, as you’ve seen above, these expensive sets are not toys and cost a significant amount of money.

An even bigger problem with expensive Lego sets is that they are often large and take up a lot of space. Not only that, but once these large sets have been completed, they cannot be easily moved. So you will either have to take it apart to move it, or you will be stuck with the Eiffel Tower in the middle of your living room. Some sets, like most of the ones mentioned above, come with stands to make displaying them easier. Look into display options before purchasing a large set, as this may determine where in your home you will build it.

If you decide to purchase an expensive Lego set, then you will likely want to build it. However, some collectors actually choose to leave these very expensive sets boxed up in the hopes that they will go up in value. This is often true, as Lego sets do typically go up in price once they retire. So you need to decide whether you want to build it or treat it as a collectible before you open the box.

Using an Expensive Lego Set: What It’s Like

The sets mentioned above all come with thousands of pieces, so they will take a long time to build. Expect it to take many days, if not weeks, to complete the largest sets. You should ensure you have a clean workspace so you don’t lose any pieces. Then once your set is complete, you will need somewhere to keep it on display. Don’t forget, keeping one of these large sets dust-free is also going to be a major task.

Frequently Asked Questions

What makes a Lego set so expensive?

The biggest factor in Lego’s pricing is the number of pieces. Larger sets are more expensive, but the size of the pieces also plays a small role. The other major factor is whether or not it is a licensed set, as those do cost more since Lego has to pay licensing fees.

How long does it take to build a Lego set?

The length of time it takes to build a set is dependent on the complexity of the set and the speed at which you work. Some people put together 500 pieces an hour, while others do that amount in a day.

Do Lego sets go up in value?

Most Lego sets do go up in value once they retire, but that is not a guarantee since some of the less popular sets do decrease. Additionally, the price of opened sets is also significantly lower than new ones.

Where can you buy the most expensive Lego set?

You will likely never see the most expensive sets in person unless you visit a Lego store. Retailers rarely sell them, and when they do, they are only available online. Your best bet is to purchase these expensive sets from a Lego store or Lego.com to at least get some VIP Points. Another good option is Amazon since they sell most of the sets.

Does Lego have any motorized sets?

Yes, Lego still has motorized sets, which are typically some of the most expensive sets. However, they only have a couple of options right now and they are mostly Technic sets.
