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? Well, besides the sensible option of boosting your savings, consider this: a breathtaking, multi-thousand-piece LEGO masterpiece. Prioritize, yes, but don't forget the joy of building something incredible, even as an adult.
LEGOs, while always a bit of an investment, have reached new heights of expense, particularly at the higher end. This isn't just arbitrary price-gouging; LEGO's commitment to quality—rigorous testing for durability and safety—along with the costs of licensing agreements for their collaborations, adds up significantly.
While the cheapest sets start around $10, the most expensive are over eighty times that price. Below, for your viewing (and perhaps purchasing) pleasure, are fifteen of the priciest LEGO sets currently available, as of January 2025. Let's hope the price ceiling doesn't climb even higher, but let's be realistic.
