So, you've come into some unexpected cash—perhaps you won your office pool, a bank made a mistake in your favor, or you received a hefty tax refund. What's next for that newfound money? Sure, you could stash it away in your savings account, but wouldn't it be thrilling to invest in a next-level, multi-thousand piece LEGO set, build it, and proudly display it in your home? After all, having fun is a priority, even for adults.
LEGO sets have never been known for being cheap, especially at the high end. The company prides itself on rigorous quality control, ensuring their bricks can withstand gravity, pressure, and even human saliva. Add to that the costs of third-party licensing agreements for collaborative partnerships, and you can see why prices soar. The least expensive LEGO set starts at around $10, but the most extravagant ones can cost over 80 times that amount. For those intrigued or considering a purchase, here are the 15 most expensive LEGO sets available in January 2025. Hopefully, we won't see even higher prices in the future, but chances are, we might.
