The 15 Most Expensive Lego Sets You Can Buy Now

So, you've come into some extra cash – maybe you won the office pool, a bank made a mistake in your favor, or your tax refund was unexpectedly generous. Now what? You could stash it all away, or you could indulge in a truly epic LEGO build – a multi-thousand piece masterpiece to proudly display in your home. Prioritizing savings is important, but let's be honest, adulting deserves a little fun too!

LEGOs have never been inexpensive, but high-end sets are pricier than ever. LEGO justifies this with their rigorous quality control: bricks are tested relentlessly against gravity, pressure, and even… human saliva! Add in the costs of licensing agreements for those incredible collaborations, and the prices quickly escalate.

The cheapest LEGO set starts around $10, while the most expensive are over 80 times that price. For your viewing (and perhaps purchasing) pleasure, here are the 15 most expensive LEGO sets available as of January 2025. Let's hope we don't need to raise this ceiling anytime soon… but we probably will.
