The 15 Most Expensive Lego Sets You Can Buy Now

So, you've come into some extra cash—a winning lottery ticket, a generous refund, or maybe just a surprisingly large bonus? What's a grown-up to do? Besides the sensible option of boosting your savings, why not indulge in a little adult fun? Consider the majestic world of high-end LEGO sets—a truly captivating way to unwind and unleash your inner child.

LEGOs have always been a bit of an investment, but the prices of their most elaborate creations have skyrocketed. This isn't just about inflation; LEGO's dedication to quality—rigorous testing to withstand everything from gravity to, yes, even saliva—plays a significant role. Factor in the licensing fees for their many collaborations, and the cost quickly adds up. You can find a basic set for around $10, but the most expensive sets are over 80 times that price!

Below, you'll find the 15 most extravagant LEGO sets currently available (as of January 2025). Prepare to be amazed (and maybe slightly intimidated by the price tags). We suspect this list will only get more impressive—and expensive—in the future.
