LEGO has grown in leaps and bounds from inexpensive plastic bricks to wallet-busting collector’s items. We checked the market to see how expensive they get.
LEGO sets are expensive. Way more expensive than they used to be. Thanks to pricey ultra-precision molds and hefty licensing deals, production costs have increased. That and the fact that LEGO deliberately (or cleverly) positions itself as a premium brand means its products are no longer simple toys. In fact, with numerous complex and display-focused kits, the company has a long-running strategy that targets adult collectors, rather than children.
Some savvy buyers even treat LEGO as an investment, and with an average 11% growth, it outperforms traditional assets like stocks and gold. Many models can be worth way more than you can imagine, with retired or hard-to-find editions gaining a lot of value over time. But let’s focus on the most expensive sets that LEGO has sold directly without delving too much into their aftermarket gains.
The most epic LEGO sets you can buy are often part of specific lines such as the Ultimate Collectors Series (UCS) or LEGO Icons. They can be recreations of real-world or fictional objects and are usually incredibly detailed. Our go-to for discovering the most expensive LEGO kits ever sold is BrickEconomy, which “provides insights into LEGO economics and market values.” And, with that, here are five of the most expensive LEGO sets ever sold, ranked by price.LEGO Titanic (10294) – $679.99
The fifth most expensive set ever sold by LEGO is the massive 9,090-piece Titanic that was launched in 2021. In fact, when it was released, it was the second-largest ever LEGO set by piece count and stretched to almost 4.5 feet long when built. The model pulls apart into three sections, and the interior is packed with surprising details. The grand staircase, cabins, dining rooms, lounges, and even a swimming pool are all inside.
But this set is very much a serious project for serious LEGO builders. There are no minifigures, not even Jack or Rose, and no gimmicky movie references. There’s no iceberg, and there’s certainly no gaping hole in the hull. This model is all about the glory of the RMS Titanic before it met its demise, and it leans hard into a realistic design. It’s part of LEGO’s Icons series and sits alongside other grown-up sets like the Eiffel Tower and the Colosseum as a serious set.
It was originally priced at an eye-watering $629.99. While it is still available through official channels, secondary market prices have already crept past $750. BrickEconomy predicts that when it’s retired, which will likely be late 2025, it will receive an immediate bump in value with a further 5% annual growth, giving an estimated resale value approaching $1,000 within 5 years.
