LEGO Retirement Analysis: Investabrick’s 2025 Best Buys Reviewed
Less than one month into 2026, Investabrick's 2025 best buy picks are already proving why readers who follow our recommendations stay ahead of the LEGO investment market. We have looked at 20 sets we highlighted throughout 2025 as top investment opportunities, 14 sets (70%) are already showing gains exceeding 10% on US secondary markets including Amazon and eBay — with six sets delivering extraordinary returns of 40% or higher in just weeks.
This early performance validates Investabrick's selection methodology and demonstrates how quickly premium LEGO sets can appreciate once retirement removes them from retail channels. While we never get every pick perfect — six sets remain flat or show modest gains — the overall portfolio shows gains of over 20% across the whole basket in under 30 days post-retirement.
For Investabrick readers who secured these sets at retail pricing throughout 2025, the results speak for themselves. Let's break down what's working and examine the early snapshot of our 2025 recommendations.
2025 LEGO Best Buys: The Early Results So Far
The Results: 70% Already Profitable
Fourteen of twenty Investabrick 2025 best buys are already selling at premiums exceeding 10% above retail price, with six sets commanding 40%+ premiums on US secondary markets. The top performers span multiple themes — Star Wars, Harry Potter, Castle, Icons, Super Mario, Marvel, and Disney — demonstrating that strategic selection across categories delivers portfolio-wide returns.
Six sets remain flat or show single-digit gains, primarily due to extended retail availability through late December and lingering stock in January 2026. When sets remain purchasable at or near RRP, secondary-market premiums cannot establish.
The Immediate Winners: Top 5 LEGO Performers
LEGO 21344 Orient Express – RRP $300, Selling at $500 (+66%)
The flagship Icons train set leads all 2025 picks with explosive 66% premium. The combination of premium $300 price point, intricate build quality, and nostalgic appeal to adult collectors created immediate scarcity post-retirement. Orient Express demonstrates how high-value display sets with broad collector appeal can appreciate fastest when retail stock disappears.
LEGO 71436 King Boo's Haunted Mansion – RRP $75, Selling at $115 (+53%)
The smallest set in our top 20 delivers second-highest percentage return at 53%. King Boo's Mansion benefited from Super Mario theme popularity, Halloween collectibility, and accessible $75 price point that enabled multiple-unit purchases. Licensed Nintendo content combined with seasonal appeal created immediate post-retirement demand.
LEGO 10305 Lion Knights' Castle – RRP $400, Selling at $600 (+50%)
The medieval castle's 50% premium reflects pent-up demand for Castle theme content after years without major releases. At $400, Knights' Castle targeted adult fans nostalgic for 1980s-90s Castle sets, creating collector base willing to pay significant premiums for this first modern Castle flagship in over a decade.
LEGO 10325 Alpine Lodge – RRP $100, Selling at $150 (+50%)
The Winter Village addition matches Knights' Castle with 50% premiums despite significantly lower price point. Alpine Lodge's seasonal appeal, modular Winter Village compatibility, and $100 accessibility made this popular for both displayers and investors. The combination of holiday theming and Icons quality creates sustained demand even weeks post-retirement.
LEGO 10312 Jazz Club – RRP $230, Selling at $340 (+48%)
The modular building rounds out the top 5 with 48% premiums. Jazz Club demonstrates Modular Buildings Collection's consistent investment performance, appealing to completionists building full cityscapes. The Art Deco aesthetic and detailed interior pushed this into premium collector territory immediately post-retirement.
Solid Performers: 21–45% Premiums
Eight additional sets show strong appreciation in the 21–45% range:
LEGO 76261 Spider-Man's Final Battle – RRP $110, Selling at $160 (+45%) Marvel content can deliver despite theme's typically slower growth, with Spider-Man's popularity driving post-retirement demand.
LEGO 75304 Darth Vader's Helmet – RRP $80, Selling at $115 (+44%) Accessible Star Wars entry at $80 delivered 44% premiums through iconic character recognition and compact display footprint.
LEGO 75978 Diagon Alley – RRP $450, Selling at $625 (+39%) The Harry Potter flagship's massive 5,544-piece count and iconic location created scarcity despite $450 premium pricing.
LEGO 21343 Viking Village – RRP $130, Selling at $180 (+38%)
LEGO 76391 Hogwarts Icons – RRP $300, Selling at $410 (+37%)
LEGO 43242 Snow White and the Seven Dwarves' Cottage – RRP $220, Selling at $290 (+32%)
LEGO 43222 Disney Castle – RRP $400, Selling at $520 (+30%)
LEGO 76178 Daily Bugle – RRP $350, Selling at $450 (+29%)
LEGO 75355 X-Wing Starfighter – RRP $240, Selling at $290 (+21%)
These nine sets represent reliable performers delivering above-market returns across Ideas, Disney, Harry Potter, Marvel, and Star Wars themes.
The Flat Performers: Six Sets Requiring Patience
Six sets remain flat or show single-digit gains, primarily due to extended retail availability:
LEGO 10297 Boutique Hotel – RRP $230, Selling at $205 (-11%)
LEGO 21335 Motorised Lighthouse – RRP $300, Selling at $300 (0%)
LEGO 76423 Hogwarts Express Train Set with Hogsmeade Station – RRP $130, Selling at $130 (0%)
LEGO 10323 Pac-Man – RRP $270, Selling at $270 (0%)
LEGO 75357 Ghost and Phantom – RRP $150, Selling at $160 (+7%)
LEGO 75354 Coruscant Guard Gunship – RRP $140, Selling at $150 (+7%)
The common thread? Extended retail availability through late December 2025 and in some cases lingering stock in January 2026. When sets remain purchasable at or near RRP, secondary-market premiums cannot establish. Two of the six come from LEGO Icons, one from Ideas, one from Harry Potter, and two from Star Wars.
These aren't failures — they're early-stage sets requiring time for retail stock to fully deplete. As 2026 progresses and genuine scarcity develops, these should begin appreciating. It's too early to draw firm conclusions on sets that retired less than 30 days ago.
What This Means for Investabrick Readers
The 2025 best buys' early performance — 70% of picks already showing 10%+ premiums, 30% delivering 40%+ potential returns — validates several critical principles:
Early identification matters. Investabrick readers had months of advance warning to acquire these sets at retail before retirement created scarcity. Casual investors who wait until retirement announcements miss optimal entry points and face inflated secondary-market pricing.
Diversification works. The winners span Star Wars, Harry Potter, Disney, Castle, Icons, Ideas, Marvel, and Super Mario at prices from $75 to $450. Strategic selection across themes and price points delivers portfolio-wide returns.
And here's the best part — Investabrick provides all this advance intelligence, strategic guidance, and market analysis completely free. Our readers gained over 20% across the whole basket of sets on resale markets in under 30 days without paying a penny for the recommendations. That's the Investabrick advantage — professional-grade LEGO investment analysis accessible to everyone.
Looking Ahead to 2026
As 2025 picks continue developing through 2026, Investabrick will soon release our 2026 best buys recommendations identifying the next generation of high-potential LEGO investments.
Meanwhile, exciting new launches are arriving in the first quarter of 2026:
LEGO Pokémon launches February 27th with first-ever official Pokémon sets — Venusaur/Charizard/Blastoise ($649.99), Pikachu ($199.99), and Eevee ($59.99). This historic partnership between two entertainment giants brings Generation 1 favourites to LEGO form for the first time.
LEGO Smart Play Star Wars debuts March 1st with revolutionary interactive technology featuring Throne Room Duel ($159.99), Luke's X-Wing ($89.99), and Vader's TIE Fighter ($69.99). LEGO Smart Bricks bring responsive sounds, lights, and motion-activated play to Star Wars battles.

Final Thoughts
It's early days — less than 30 days post-retirement for most of these sets — but the initial snapshot is extremely positive. Fourteen of twenty Investabrick 2025 best buys are already commanding premiums on secondary markets, with six sets showing extraordinary 40%+ returns. The six flat performers need time for retail depletion before secondary markets mature.
For readers who followed our 2025 recommendations, you're sitting on significant paper gains with flexibility around whether to hold long-term or take profits. For readers who missed 2025 opportunities, the message is clear: Investabrick's advance intelligence delivers results.
