Imagine you've come into some unexpected money—perhaps you won your office pool, benefited from a banking error, or received a generous tax refund. What will you do with this windfall? While stashing it away in a savings account is a practical choice, there's also the allure of indulging in a high-end LEGO set, assembling it, and proudly displaying it in your home. After all, even adults deserve to have fun and enjoy their hobbies.
LEGO has never been considered cheap, and the premium sets have reached new heights of expense. The company justifies this with a commitment to quality, rigorously testing their bricks against various stresses including gravity, pressure, and even human saliva. Additionally, the costs escalate due to third-party licensing agreements for their collaborative projects. While the most affordable LEGO set starts at around $10, the priciest can exceed $800, showcasing a wide range of options for enthusiasts.
Here, for your intrigue and potential purchase, we present the 15 most expensive LEGO sets currently available as of January 2025. We hope not to see prices climb even higher, but it seems inevitable.
