BrickLink led March at 15.8% average yearly appreciation while DREAMZzz stayed negative at -1.2%
March’s clearest signal is the gap between the market’s leaders and laggards. Across 17,966 active sets tracked, the overall average yearly appreciation sits at 6.2%. That is a healthy middle ground, but the spread inside that average matters more than the headline. BrickLink, BrickHeadz, Ideas, Architecture, Icons, and Ninjago all ran well above the market rate. At the other end, Disney, Mindstorms, Mursten, and DREAMZzz trailed badly, with DREAMZzz the only major theme in negative territory at -1.2%.
The retirement pipeline is also getting crowded. There were 19 sets retired this month, and 78 more are now flagged as retiring soon. That does not tell you where prices go next on its own, but it does tell you where supply conditions are about to change. March looks less like a broad market surge and more like a rotation toward themes with tighter supply, collector identity, and shorter production runs.

The broad market number, 6.2%, is respectable but not euphoric. That matters because it suggests March was not a month where nearly everything rose together. Instead, performance stayed selective. Themes with collector depth and constrained supply kept their premium, while large evergreen themes with heavy retail exposure were more mixed.
The retirement data points in the same direction. Nineteen retirements in one month is enough to move attention toward near-term exits, especially in themes that already have strong secondary-market behavior. The 78 sets now marked as retiring soon create a fairly dense watchlist for April and May.

BrickLink remains the standout at 15.8% across 63 tracked sets. That is not a surprise if you follow how limited-run, adult-focused product behaves after release, but the size of the lead still matters. BrickLink is 9.6 percentage points ahead of the overall market average. It also has 10 sets retiring soon, which keeps supply pressure in focus. This theme continues to trade more like a scarcity-driven collectible segment than a standard retail line.
BrickHeadz and Ideas are close behind at 12.8% and 12.6%. Both themes have the same trait investors tend to reward: clear collector identity. BrickHeadz has 160 tracked sets and 60 retiring soon, which is a large near-term funnel. Ideas has only 53 tracked sets, but 27 are retiring soon. That is an unusually high share of the line. When that many sets are near exit inside a theme that already posts double-digit average appreciation, it usually keeps attention concentrated on the category.
Ninjago deserves special mention because it combines scale with strong performance. At 356 tracked sets and 11.3% average yearly appreciation, it is not just a niche winner. It is one of the larger themes in the market, and it still sits 5.1 percentage points above the overall average. With 98 sets retiring soon, Ninjago has one of the heaviest near-term retirement pipelines in the dataset. That makes it one of the most important themes to watch over the next few months.
Star Wars came in at 8.8% across 716 tracked sets. That is still comfortably above the market average, but it is not leading the field. The more notable figure is 122 sets retiring soon, one of the biggest counts in the report. Star Wars remains deep and liquid, but March suggests the theme is acting more like a mature market than a momentum leader. That often means the most movement will be concentrated in specific exits rather than spread evenly across the full line. Notable retired-market anchors in this space, such as {{SET:75192-1}}, still shape buyer expectations even when the theme average is more moderate.
At the weaker end, Disney posted 3.4% across 138 sets, Mindstorms posted 2.9% across 66, and DREAMZzz fell to -1.2% across 32. DREAMZzz also has all 32 tracked sets marked as retiring soon. That is the kind of data point that gets attention, but it cuts both ways. A full-line retirement wave can tighten supply, yet a negative average appreciation rate tells you demand has not been strong enough so far to offset that pressure. March does not show collector conviction there.
Top movers
The biggest monthly movers were spread across very different parts of the catalog, which is a reminder that short-cycle price action can be idiosyncratic even when broader theme trends are stable.
Top 5 gainers
LEGO Number and Symbol Blocks led the month with 19.9% rolling growth and a current estimated price of $40.04. The interesting part is not just the gain, but the theme context. Dacta’s average yearly appreciation is only 3.5%, so this was a set-specific move rather than theme-wide strength.
Creator Value Pack rose 19.8% to $239.70. Creator as a theme sits at 6.7%, almost exactly in the market’s middle tier, so this is another case where individual scarcity or buyer attention likely mattered more than the theme average.
Shell Service Station gained 19.7% and now carries a current estimated price of $749.99. Town’s average yearly appreciation is 6.2%, right on the market average, but classic service station and fuel branding sets often attract a different collector than standard Town inventory. This kind of move fits that pattern.
Airline Promotional Set added 19.6% to reach $100.96. World City is already strong at 11.4%, so this gainer fits a theme that has been outperforming more broadly.
San Diego Comic-Con 2008 BrickMaster climbed 19.4% to $1,589.79. Indiana Jones averages 10.2%, but convention-exclusive material trades on a scarcity curve of its own. High-end promotional sets are often thinly supplied, so price discovery can move sharply when even a small number of transactions reset the market.
Top 5 decliners
Crocodile Legend Beast had the weakest month, down 20.0% to $42.22. Legends of Chima averages 5.3%, so the set’s move was far worse than the theme baseline.
Dual FX Racers fell 19.9% to $234.00, a sharp reversal inside the otherwise average Town category. Mechanical Pencil & Pen Set also dropped 19.9% to $17.44, which fits the more volatile behavior often seen in Gear, where the theme average is only 4.3% across a very large 2,069-set catalog.
V-belts / Rubber Bands slipped 19.8% to $14.04. Service Packs rarely behave like mainstream collectible sets, and March did not change that. Snow Resort Hot Chocolate Van also declined 19.8%, landing at $62.14. Friends is one of the bigger underperforming modern themes in this report, with 4.1% average yearly appreciation across 480 sets and 131 retiring soon. That retirement count is huge, but March suggests supply exits alone have not yet translated into stronger pricing across the line.
Retirements and new watches
March recorded 19 retirements and pushed 78 sets into the retiring-soon group. The raw count matters, but the theme distribution matters more.
City has 130 sets retiring soon, the largest count in the dataset. Friends is close behind at 131, Star Wars has 122, Marvel Super Heroes has 114, and Ninjago has 98. Super Mario has 83, Disney has 70, and BrickHeadz has 60. That is a wide retirement wave across both evergreen play themes and collector-focused lines.
There are two ways to read that. First, large retirement counts in big themes often create a lot of noise because not every set exits with the same demand profile. City at 6.1% and Friends at 4.1% are good examples. These are massive themes with many retiring sets, but the theme averages do not point to broad-based premium pricing. Second, retirement counts inside already strong themes deserve more attention. BrickHeadz at 12.8% with 60 retiring soon, Ideas at 12.6% with 27 retiring soon, Icons at 11.3% with 46 retiring soon, and Ninjago at 11.3% with 98 retiring soon form the more interesting cluster.
DREAMZzz is the most unusual retirement-watch case in the report. All 32 tracked sets are retiring soon, yet the theme average is -1.2%. That combination usually means the market has not settled on post-retail value yet. If prices start firming after exits, the theme could look very different by summer. If not, March will look like an early warning that retirement alone was not enough.
Monkie Kid also stands out. It has 42 tracked sets, 31 retiring soon, and 8.1% average yearly appreciation. That is not top-tier performance, but it is above the market average and paired with a very high share of near-term retirements. It is the kind of theme that can move quickly if supply thins faster than expected.
For readers tracking marquee collector lines, the retirement watch list reinforces a simple point. The next few months are likely to be defined less by broad market beta and more by timing around exits. That is especially true in themes where collector demand is already established, such as Ideas, Icons, BrickHeadz, Ninjago, and selected Star Wars sets like {{SET:75331-1}} or long-tail flagships that shape the category narrative such as {{SET:75192-1}}.
What March suggests for the next few months
March points to a market that is still healthy, but increasingly selective. The 6.2% overall average yearly appreciation is solid. The stronger message is that collector-led themes are widening the gap over broad retail themes. BrickLink at 15.8%, BrickHeadz at 12.8%, Ideas at 12.6%, Architecture at 11.9%, Icons at 11.3%, and Ninjago at 11.3% are not just beating the market, they are doing it by a meaningful margin.
The retirement calendar suggests April through early summer will put more pressure on that split. If 78 sets are already marked as retiring soon after 19 retirements this month, the next phase is likely to center on repricing inside themes with both strong demand and a high share of exits. That puts BrickHeadz, Ideas, Icons, Ninjago, Monkie Kid, and selected Star Wars segments near the front of the conversation.
At the same time, March argues against treating all retirements as equal. Friends, City, Disney, and DREAMZzz all have large or concentrated retirement exposure, but their average appreciation rates are much weaker. In other words, the data does not support a simple “retiring soon equals strong secondary performance” rule. The better read is narrower: retirement pressure matters most when it meets an audience that already collects the theme aggressively.
If this pattern holds, the next few months should bring more dispersion, not less. Expect the market’s winners to keep coming from themes with strong collector identity and tightening supply, while broad play themes continue to produce isolated standouts rather than uniform gains. March made that distinction pretty clear.
