So, you've come into some unexpected cash—perhaps you won your office pool, a bank made an error in your favor, or you received a hefty tax refund. What are you planning to do with it? You could stash it away in your savings account, or you could splurge on a next-level, multi-thousand piece LEGO set, build it, and proudly display it in your home. It's crucial to have priorities, and let's be honest, having fun as an adult is a priority too.
LEGO has never been considered cheap, and the high-end sets have become increasingly expensive. The company attributes this to their commitment to quality, rigorously testing their bricks against gravity, pressure, and even human saliva. Factor in the costs of third-party licensing agreements for their collaborative partnerships, and you can see why the prices can skyrocket.
The cheapest LEGO set currently available is around $10, while the priciest one is over 80 times that amount. Here's a list of the 15 most expensive LEGO sets you can buy as of January 2025, for your morbid curiosity or potential purchase. Let's hope we don't see even higher prices in the future, though it's likely we will.
