Could something on your shelf be worth more than you paid?
Before we show you the numbers, make a guess. Drag the price tag to what you think this set sells for today, still sealed in its box.

Explore the rarest sets and their price evolution.
When a set retires, production ends, but collectors keep looking. Nostalgia, rare editions and completing a collection can push resale prices higher. Retirement alone doesn’t guarantee a gain.

More than a price tag.
Collecting isn’t only about profit. It’s also about nostalgia, rarity, completion and community. Every collection has a story, and sometimes its financial value can be just as surprising.

How we built it
Introduction
Our audience is the LEGO collector: adult fans who buy sets to display, to complete a theme or as an investment, and who follow retirement dates and resale prices closely. This story answers the question collectors ask about their own shelves: what happens to a set’s value after LEGO stops making it?
Related work
We drew on The Pudding’s scroll-driven explainers, the NYT’s “How Fast is Usain Bolt?” for the single-number hook, and Gapminder for comparing many cases on one log scale. BrickEconomy and Brickset already publish price histories, but as tables for experts, not as a story.
Methodology
Retail prices, release years and community counts come from Brickset; 2026 value estimates come from BrickEconomy. Regional values and purchase-cost curves are illustrative. The shelf catalog holds 15,408 of Brickset’s sets; where no US launch price exists, we estimate one from piece count, theme and inflation and mark it ≈. Prices run from $2.99 to over $17,400, so the price chart and the continent towers use a log scale; the shelf towers use a linear scale.
Design
Brick-built marks tie the charts to the subject. The globe and the continent towers always show the same set and the same continent, so either view can drive the other. Millennium Falcon 75192 sits next to the rare sets to show that size and fame alone don’t raise a price: it still sells at retail and resells below it. An earlier version showed each continent’s “standout set” on the globe, which confused readers, so we dropped it.
Implementation
We built the site with Claude and created visual assets with Google Flow.

Future work
Pull live prices from the BrickEconomy API, add real regional sales data, and adjust for inflation.
