Best LEGO Sets Retiring in 2026 - Investment Guide (September)

Top retiring LEGO sets by investment potential

September 2026 has 111 LEGO sets marked for retirement, which gives collectors a wide field to sort through. The market data for the strongest candidates is fairly clear. The best-ranked sets combine one or more of four traits: a large collector audience, limited direct competition inside their theme, strong early price support above retail, and a two-year projection that still leaves room after the set exits shelves.

This list is not just a ranking of the biggest premiums today. Some sets already trade well above retail, while others rank highly because their current pricing still looks relatively restrained compared with their audience appeal and post-retirement setup. That distinction matters. A set sitting at a modest premium can be more interesting than one that already made most of its move.

At the top end, large-format display models dominate. Eiffel Tower leads the list with a current estimated price of $776.00 against a retail price of $629.99, and a two-year projection of $864.42. But the list is not only about giant adult-targeted sets. There are also strong entries from City, Ninjago, Monkie Kid, and Super Mario, where lower entry prices and faster annual growth rates create a different kind of opportunity.

Set Number Name Retail Price Current Value Premium % 2-Year Projection
Eiffel Tower Eiffel Tower $629.99 $776.00 23.2% $864.42
Jabba's Sail Barge Jabba's Sail Barge $499.99 $548.74 9.8% $597.50

Christmas Tree Decoration Christmas Tree Decoration $329.99 $419.90 27.2% $439.38
The City Tower The City Tower $209.99 $265.71 26.5% $279.21
Monkey King Ultra Mech Monkey King Ultra Mech $159.99 $184.11 15.1% $198.51
Dune Atreides Royal Ornithopter Dune Atreides Royal Ornithopter $164.99 $168.59 2.2% $179.25

Jaws Jaws $149.99 $159.99 6.7% $177.47
Lloyd’s Jet Mech Lloyd’s Jet Mech $109.99 $134.43 22.2% $142.31

#1 Eiffel Tower

Eiffel Tower is the clearest heavyweight in this group. It has the highest current estimated price at $776.00, the highest projected price at $864.42, and one of the strongest ratings at 4.90. The set already carries a 23.2% premium over its $629.99 retail price, which is significant for a product this expensive.

The size matters here. At 10,001 pieces, it is one of those landmark LEGO releases that attracts a very specific buyer, adult collectors who want a large display model and are willing to pay for one. Sets in that category do not rely on minifigures or play value. They depend on shelf presence, brand recognition, and the fact that replacement options are rare. The Eiffel Tower has all three.

The yearly price change of 5.7% is not the fastest on this list, but that is not a weakness in context. Large premium sets often move more gradually because the buyer pool is narrower, and the absolute dollar amounts are much higher. A rise from $629.99 retail to $776.00 current value already represents meaningful support before retirement is fully in the rear-view mirror.

Among retiring sets, this one looks like the most complete package: top-tier rating, iconic subject matter, a mature adult audience, and a current market that already accepts a price well above retail.

#2 Jabba's Sail Barge

Jabba's Sail Barge ranks second because it sits in one of the most reliable collector categories LEGO has, Star Wars Ultimate Collector Series. The retail price is $499.99, the current estimated price is $548.74, and the two-year projection is $597.50. That puts it at a 9.8% premium today, with a yearly price change of 7.3%.

This is a different profile than the Eiffel Tower. The price point is still high, but the collector base is broader because Star Wars UCS buyers tend to be active both during retail life and after retirement. On top of that, this set includes 11 minifigures, which gives it another layer of demand beyond the ship itself. Large Star Wars sets with strong character selection often have more than one reason for buyers to come back later.

The rating is 4.90, equal to the top set in this ranking. That matters because premium UCS releases can be hit or miss if fans do not connect with the subject. In this case, the market data suggests the opposite. The set has already moved above retail, and the projected climb to $597.50 is healthy without looking overheated.

If there is one thing that makes this set especially worth watching, it is the combination of franchise strength and collector format. UCS is one of the few labels that can support high aftermarket prices even when the original retail price is already substantial.

#3 Grand Piano

Grand Piano is one of the more unusual entries in the ranking, and that is exactly why it holds up well. It comes from Ideas rather than a movie license or evergreen action theme, and it targets display collectors first. The set retailed at $399.99, has a current estimated price of $427.19, and carries a two-year projection of $456.17.

The current premium is 6.8%, which is not flashy. Still, this set earns its place because the concept is distinctive enough that it does not have many direct substitutes. A LEGO piano is not a routine product. Collectors who skipped it during retail life may have very few comparable options later, and that kind of niche can support prices after retirement.

Its yearly price change is 3.4%, lower than several others here, so this is not a momentum story. It is more about stability. The 4.90 rating suggests sustained collector approval, and a large Ideas set with 3,662 pieces has a different demand curve than a character vehicle or a playset. Buyers are often older, more patient, and less price-sensitive when the model fits a home display or music-themed collection.

This is one of the better examples of a set that may not dominate on short-term growth rate, but still looks durable because its appeal is narrow in a good way. It does one thing, and it does it well.

#4 Christmas Tree Decoration

Christmas Tree Decoration has one of the strongest current premiums in the entire ranking. It retailed at $329.99 and now carries an estimated price of $419.90, a 27.2% premium. Only one set here is close to that level, and its yearly price change of 12.1% adds more evidence that demand has been active.

Seasonal sets often behave differently from standard retail products because they have a built-in annual demand cycle. That does not automatically make them strong aftermarket performers, but when a seasonal set is large, well-rated, and already trading well above retail before retirement, it deserves attention. This one checks those boxes, with a 4.70 rating, 3,171 pieces, and seven minifigures.

The two-year projection of $439.38 suggests more modest upside from the current $419.90 than some other entries. That is the tradeoff. A lot of the move has already happened. Even so, the data says the market has given this set a strong premium early, which is usually a sign that supply and demand are not in balance at retail pricing anymore.

This is one of the more interesting names on the list because it does not fit the usual script. It is not a giant Star Wars set or a famous architecture model. It is a seasonal product that the market has treated like a collector piece.

#5 The City Tower

The City Tower is the most convincing non-licensed mainstream playset in the ranking. The numbers are hard to ignore: $209.99 retail, $265.71 current estimated price, 26.5% premium, and a two-year projection of $279.21. Its yearly price change is 20.7%, which is one of the fastest rates in this group.

City sets do not usually get the same attention as adult display models, which is exactly why this one stands out. A strong City release can benefit from broad buyer interest, families, younger builders, and later collectors who want a flagship-style example from the theme. With 1,941 pieces and seven minifigures, this set has enough scale to feel substantial without crossing into ultra-premium territory.

The 4.80 rating supports the idea that buyers responded well to it during retail life. More importantly, the market is already pricing it far above retail. A 26.5% premium in City is not normal background noise. It suggests this set has broken out from the pattern that keeps many standard City products closer to retail for longer.

If you are looking for the set in this ranking with the strongest blend of accessibility and momentum, this is one of the best examples. It is not cheap, but it is far easier to enter than the top three, and the market has rewarded it quickly.

#6 Monkey King Ultra Mech

Monkey King Ultra Mech sits in a theme that often gets less mainstream attention in North America than it deserves. That can create a strange market setup: lower broad awareness during retail life, followed by tighter supply once the set is gone. Here, the numbers are solid. Retail is $159.99, current estimated price is $184.11, the premium is 15.1%, and the two-year projection is $198.51.

The yearly price change is 3.9%, so this is not a rapid mover. But Monkie Kid has a history of producing sets that age well with collectors who appreciate the theme’s design work. This one has 1,705 pieces, six minifigures, and a 4.80 rating. For a mech-focused release, that is a strong package.

What makes it worth watching is the theme context. Mechs are common across LEGO, but Monkie Kid mechs tend to have a more distinct visual identity than generic robot builds. That gives them a collector audience that is smaller than Star Wars or Icons, yet often more committed once sets disappear from shelves.

This is not the safest set in the ranking, and the market data reflects that with a moderate rather than explosive projection. Still, it has already established a healthy premium above retail, which is a useful sign for a theme that does not always get immediate aftermarket attention.

#7 Dune Atreides Royal Ornithopter

Dune Atreides Royal Ornithopter is one of the most interesting cases here because the current premium is still very low. Retail is $164.99, current estimated price is $168.59, and the premium is only 2.2%. Yet it still ranks seventh, ahead of some sets with stronger current gains.

The reason is simple. This is an Icons licensed set tied to a property with a strong adult fan base, and it has eight minifigures packed into a 1,369-piece model. That is a lot of collector appeal for the price point. The market has not pushed it far above retail yet, but the two-year projection of $179.25 suggests the post-retirement setup is still constructive.

Its yearly price change is 3.2%, which is subdued. So this is not a case where the market is rushing in early. That can cut both ways. On one hand, it means less proof of current demand than the stronger premium names. On the other, it means the set has not already run too far before retirement.

Among all ten ranked sets, this may be the one where theme relevance matters most. Dune does not have a long LEGO shelf history, and that scarcity can matter later. If collectors decide this is the definitive LEGO version of the Ornithopter for a while, the current near-retail pricing may look unusually calm in hindsight.

#8 Super Mario World: Mario & Yoshi

Super Mario World: Mario & Yoshi has one of the better projection gaps in the ranking. It retailed at $129.99, has a current estimated price of $150.00, and a two-year projection of $177.64. That is already a 15.4% premium over retail, even though the yearly price change is listed at 0.0%.

That zero is unusual, and it introduces some uncertainty into the short-term trend. Still, the set’s place in the ranking makes sense. This is not a standard Super Mario expansion set. It is a display-driven model tied to one of Nintendo’s most recognizable character pairings. The audience extends beyond active LEGO Super Mario buyers.

With 1,215 pieces and no minifigures, this set depends almost entirely on display appeal and nostalgia. That is not a weakness here. In fact, it may be the main reason it has held a premium. Character-based Nintendo products often attract collectors who are less interested in play features and more interested in iconic imagery.

The projected move to $177.64 is one of the more appealing increases relative to current value in this list. If the current flat yearly change looks odd, the broader pricing still says the market sees this as more than a routine licensed set.

#9 Jaws

Jaws is another Ideas release with a licensed hook, and that combination has worked well for LEGO when the subject is culturally recognizable. The set retailed at $149.99, has a current estimated price of $159.99, and is projected at $177.47 in two years. The current premium is 6.7%, with a yearly price change of 5.5%.

This is a compact but focused collector set. At 1,497 pieces and three minifigures, it is not trying to compete with the largest display models. Instead, it leans on a famous film property and the kind of buyer who wants a conversation-piece set on a shelf. Ideas is often at its best when it turns a specific cultural reference into a self-contained display model, and Jaws fits that pattern well.

The current premium is moderate, which keeps it behind stronger movers higher on the list. But the market is clearly supporting it above retail, and the projected price of $177.47 gives it a respectable path after retirement. The 4.80 rating also matters because licensed nostalgia sets can cool off quickly if the build itself does not satisfy collectors. That does not appear to be the issue here.

Jaws is not the highest-upside set in this ranking, but it has one of the cleaner collector stories: a single iconic property, a recognizable display subject, and a price point that stays within reach for a broad adult audience.

#10 Lloyd’s Jet Mech

Lloyd’s Jet Mech rounds out the list, and it earns the spot through momentum more than sheer scale. Retail is $109.99, current estimated price is $134.43, the premium is 22.2%, and the two-year projection is $142.31. Its yearly price change of 18.2% is one of the strongest in the ranking.

Ninjago has a long track record of producing aftermarket winners, especially when a set combines a popular lead character with a format fans consistently buy. Mechs are one of those formats. This set has 1,112 pieces, five minifigures, and a 4.80 rating, which is a strong value profile inside the theme.

The reason it ranks tenth rather than higher is that the projected increase from the current $134.43 to $142.31 is narrower than several other sets above it. In other words, the market has already rewarded it quickly. That is good evidence of demand, but it also means less room in the near-term projection than the current premium alone might suggest.

Even so, this is one of the clearer examples of a set where theme loyalty is doing real work. Ninjago buyers tend to return for standout vehicles and mechs after retirement, and this set’s early price action suggests it has already separated itself from the average action-theme release.

What the ranking shows

The most useful pattern across these ten sets is that there is no single winning formula, but there are clear clusters. The biggest sets, Eiffel Tower, Jabba's Sail Barge, and Grand Piano, lean on adult display demand and high ratings. Mid-priced standouts such as The City Tower and Lloyd’s Jet Mech lean on fast annual growth and strong premiums over retail. Then there are specialty cases like Dune Atreides Royal Ornithopter and Jaws, where the current premium is still modest, but the collector story is strong enough to keep them in the conversation.

One more point stands out. The strongest current premiums are not all coming from the usual prestige themes. Seasonal and City both placed near the top, with Christmas Tree Decoration at 27.2% and The City Tower at 26.5%. That is a reminder that the market is rewarding sets that feel distinct inside their own category, not just the ones with the most famous logo on the box.

If you compare current value to the two-year projections, several sets appear to have already done a large part of their early move, while others are still closer to retail and may depend more on post-retirement follow-through. That split is probably the most practical takeaway in this group. The data does not point to one uniform type of retiring winner. It points to two: sets the market already chased above retail, and sets with enough collector identity that retirement may matter more than it does for an average release.
