What is your LEGO® really worth? We tested the tools that tell you.

Price checkers, value guides and portfolio trackers all promise to reveal what your sets are worth — but most show asking prices or guesses. We ranked the 6 that actually help you decide before you sell.

6 tools tested hands-on Real sold-price accuracy checked Last updated: July 2026

BrickGains Best for sellers & investors

Portfolio with live value, ROI and buy/hold/sell verdicts
Value in your own country & currency, in 8 languages
Newer name — smaller community than the veterans

BrickEconomy Best for forecasts & deep data

The data heavyweight of the LEGO world: values, growth charts and AI-predicted future prices across a huge catalog. Powerful, if you can stomach the density.

Enormous catalog with historical value trends
Collection tracking and forecast estimates
Forecasts are predictions you can't verify
Dense interface; best features are paid

4.4/5

BrickLink Price Guide Best for raw marketplace data

The price guide inside the world's biggest LEGO marketplace. The underlying data is excellent — but it's built for traders, not for someone who just wants a clear number.

Straight from real marketplace transactions
Free and extremely detailed
Mixes asking & sold prices; steep learning curve
No portfolio, ROI or sell alerts

Brickset Best for cataloguing a collection

A beloved community database. Superb for logging every set you own and reading reviews — value tracking is there, but it's a side feature, not the point.

Clean catalog, reviews and a big community
Free collection management
Value data is secondary and less precise
No sell timing or ROI focus

3.9/5

BrickPicker Best for US collector forums

One of the original LEGO investing communities, with a price guide and active US-centric forums. Great knowledge — the tooling just shows its age.

Deep community and investing know-how
Dated interface, mostly US pricing
No live portfolio or sell alerts

Rebrickable Best for parts & MOC builders

The go-to for parts, inventories and custom builds (MOCs). You can track owned sets, but it isn't designed to tell you what they're worth or when to sell.

Unbeatable for parts and build ideas
Not a value or investment tool
Value only via third-party add-ons

How we ranked them

Accuracy first

We compared each tool's numbers against real completed sales on BrickLink and eBay. Asking prices and unverifiable forecasts scored lower.

Made for deciding

A worth-it tool doesn't just show a figure — it helps you decide to hold or sell. Portfolios, ROI and alerts earned points.

Effortless for anyone

Most people aren't data analysts. Tools that gave a clear answer in seconds — on mobile — ranked above the power-user maze.

Our #1 pick: try BrickGains free

Check any set's real resale value in seconds — no account needed to start. See what your collection is worth today and never sell a set too cheap again.

Frequently asked

What's the best free tool to value LEGO sets?

For a clear, real number in seconds, we rank BrickGains first — it's free to start and shows what sets actually sold for. BrickLink's price guide is also free but is built for traders and mixes asking prices with sold ones.

Why not just use BrickLink or BrickEconomy?

BrickLink has great raw data but no portfolio, ROI or sell timing, and it's easy to read an asking price by mistake. BrickEconomy leans on AI forecasts you can't verify. BrickGains focuses on the number that matters when you sell: what buyers really paid.

Are these prices what I'll actually get if I sell?

Real sold-price tools (like our top pick) get you closest, because they're based on completed transactions. Final price still depends on condition, completeness and marketplace fees — always factor those in before listing.
