LEGO sets likely retiring soon from 2023 and 2024

There are 1,490 sets in the catalog released in 2023 or 2024, which puts all of them inside the window collectors usually watch for retirement. LEGO does not publish retirement dates for any set. The window is just an inference built from release year, since most sets stay in production for roughly two to three years before they're phased out. As of now, the 2023 sets are about three years old and the 2024 sets about two, so both groups sit squarely in that zone.

This report walks through the biggest sets in that window by piece count and by theme, so you can see where the exposure actually concentrates. No prices or values are mentioned anywhere below, because this site doesn't track that.

The window, honestly

Nobody outside LEGO knows exactly when a given set stops shipping. What collectors do is watch the release year and apply the rough two-to-three-year pattern that's held for most of the catalog historically. A set from 2023 that's still on shelves today has likely reached the far edge of that pattern. A set from 2024 still has some runway, but it's close enough to flag.

That's the entire basis for every claim in this post. There's no leaked retirement list, no internal memo, just release year compared against today's date. Treat the window as a probability, not a countdown.

It's also worth saying plainly: this site carries no market or retail price data. Nothing here speaks to what a set is worth, what it resold for, or whether it's appreciated. The only numbers used are piece counts, minifig counts, release years, and theme counts.

The biggest sets in the window

Sorting the 2023–2024 releases by piece count puts a few unmistakable flagship sets at the top. Lord of the Rings: Rivendell (10316) leads with 6,181 pieces and 21 minifigs, followed closely by NINJAGO City Markets (71799) at 6,163 pieces, also with 21 minifigs. Both came out in 2023 in LEGO Icons and LEGO Ninjago respectively, and both are exactly the scale of set that tends to get discontinued once a successor or seasonal refresh arrives.

The Lord of the Rings: Barad-dûr (10333) follows at 5,478 pieces, a 2024 LEGO Icons release, then Venator-Class Republic Attack Cruiser (75367) at 5,381 pieces in LEGO Star Wars. Avengers Tower (76269) brings 5,202 pieces and 31 minifigs to LEGO Super Heroes Marvel, the highest minifig count of any set in this list. Rounding out the top tier are Disney Castle (43222) at 4,837 pieces in LEGO Disney and Gringotts Wizarding Bank – Collectors' Edition (76417) at 4,809 pieces in LEGO Harry Potter.

The full ranked list below runs forty sets deep and covers everything from LEGO Architecture and LEGO Modular Buildings to LEGO Technic and the LEGO LEGO Ideas and CUUSOO line. It's a useful reference if you're deciding what to track first.

A few sets outside the absolute top of the chart are still worth a second look, including Notre-Dame de Paris (21061) at 4,382 pieces in LEGO Architecture and Batman: The Animated Series Gotham City (76271) at 4,210 pieces in LEGO Super Heroes DC. Both are large enough and specific enough to a theme that they're unlikely to get a direct reissue.

Which themes carry the most exposure

Counting sets rather than pieces changes the picture. LEGO BrickLink Designer Program shows up constantly in the piece-count list too, with entries like Studgate Train Station (910002), Mountain Fortress (910029), Mountain View Observatory (910027), Parisian Street (910032), Modular Construction Site (910008), Brick Cross (910034), Ominous Isle (910038), Logging Railway (910035), Winter Chalet (910004), Old Train Engine Shed (910033), and Ocean House (910036). These are a different case from everything else here: they're produced in limited runs by design, not phased out after a typical multi-year sales life, so their departure from availability can happen faster than the usual window suggests.

LEGO LEGO Ideas and CUUSOO is the other theme with heavy representation, including The Botanical Garden (21353), Dungeons & Dragons: Red Dragon's Tale (21348), The Orient Express Train (21344), Hocus Pocus (21341), Disney Tim Burton's The Nightmare Before Christmas (21351), Viking Village (21343), and A-Frame Cabin (21338). Ideas sets don't carry the same hard production caps as BrickLink Designer Program releases, but they do tend to cycle out once the fan-vote pipeline delivers newer projects.

LEGO Technic and LEGO Icons both place several large sets in the window as well, among them McLaren P1 (42172), Mercedes-Benz G 500 PROFESSIONAL Line (42177), Liebherr Crawler Crane LR 13000 (42146), Volvo FMX Truck & EC230 Electric Excavator (42175), NASA Artemis Space Launch System (10341), Medieval Town Square (10332), The Endurance (10335), PAC-MAN Arcade (10323), Eldorado Fortress (10320), Land Rover Classic Defender 90 (10317), and Concorde (10318). The full theme-by-theme breakdown is below.

Licensed themes spread their exposure more thinly across individual sets but still carry real weight, with Jabba's Sail Barge (75397), Hogwarts Castle and Grounds (76419), The X-Mansion (76294), The Burrow – Collectors' Edition (76437), and Chewbacca (75371) all sitting in the 2023–2024 window inside LEGO Star Wars, LEGO Harry Potter, and LEGO Super Heroes Marvel.

What to prioritise

If you're deciding what to track down first, start with the BrickLink Designer Program entries regardless of their exact release year. They're built around limited production from the start, so the usual two-to-three-year assumption doesn't really apply to them the way it does to mainline sets. Mountain Fortress (910029) and Parisian Street (910032), both from 2024, are already closer to the edge of that limited run than their age alone would suggest.

After that, the large licensed sets deserve attention because licensing arrangements can shift independently of the normal retirement pattern. Venator-Class Republic Attack Cruiser (75367) and Jabba's Sail Barge (75397) in LEGO Star Wars, Gringotts Wizarding Bank – Collectors' Edition (76417) and Hogwarts Castle and Grounds (76419) in LEGO Harry Potter, and Avengers Tower (76269) and The X-Mansion (76294) in LEGO Super Heroes Marvel are all large enough that they're unlikely to get restocked once they're gone.

Finally, the Icons flagships are worth a look simply because of scale. Lord of the Rings: Rivendell (10316), The Lord of the Rings: Barad-dûr (10333), and NASA Artemis Space Launch System (10341) are the kind of centerpiece builds that typically get one production run and then step aside for the next year's equivalent.

• BrickLink Designer Program sets: short runs by design, check availability first.
• Large licensed sets: Star Wars, Harry Potter, Marvel, DC entries over 3,000 pieces.
• Icons flagships: typically one production cycle per year.

Use the piece-count and theme tables as a checklist against your own collection rather than a shopping list based on urgency alone, since nothing here tells you how close any single set actually is to disappearing; the BrickLink Designer Program entries are the one category where the usual two-to-three-year assumption doesn't apply and genuinely deserve faster action.
