So, you've come into some extra cash—maybe you won an office pool, received an unexpected bank deposit, or got a hefty tax refund. What's the plan for this windfall? You could safely tuck it away in a savings account, or indulge in something truly spectacular: a multi-thousand piece LEGO set to build and showcase in your home. Priorities are important, but so is having fun, even as an adult.

LEGO has never been cheap, but the high-end sets have reached new heights of expense. The company stands behind its quality, rigorously testing its bricks against gravity, pressure, and even human saliva. Add to that the costs of third-party licensing agreements for collaborative partnerships, and you understand why prices can soar. The cheapest LEGO set starts at about $10, while the priciest can be over 80 times that amount. Below, we dive into the 15 most expensive LEGO sets available for sale as of January 2025, for your curiosity and potential purchase.
