How do we determine current values and estimated future values?

BrickEconomy price estimation is based on Artificial Intelligence (AI) via Machine Learning (ML) to provide an accurate estimated and predicted price of every new/sealed set and minifig. Currently, when you look at the current value of a set or minifig or an estimated future price prediction this data is based on our machine learning technology. It's not only very cool, but it is extremely accurate! We use a variety of algorithms to train our ML predictions but typically rely on neural network regression and linear regression models. Additionaly we are contstantly re-training our models and have various ones for sets and minifigs. Even cooler, our machine learning model can even predict future gains for newly released sets at an 89% accuracy rate!

Where to we get pricing data from?

We get our pricing data from a number of sources both online and off. We have established relationships with various resources as well as use APIs available on secondary markets. You can find a list below of many of our sources: eBay, Amazon, LEGO Store, LEGO Shop-at-home, LEGO Education, Bricklink, StockX, Walmart, Target, Google Express, Catawiki, Brick Owl, The Plastic Brick, Zavvi, OldLego, ToyWiz, Fat Brain Toys,, Mercari and dozens more. (Please note, this is not an updated list and some sources no longer provide us with prices.)

How do we determine a set's theme and subtheme?

We try to align with some of the industry standard sites we love including Brickset and Bricklink. These are by far two of the best LEGO sites and definitive resources for categorizing sets.

How can I see pricing data in my currency?

Currently, we support a number of regions around the world so that you can see specific pricing data based on your region's currency. If you are on a mobile device, look for the 'Region' link on the bottom of the page near the footer. If you are on a desktop the 'Region' link will be on the top right of the page. If you are signed in to BrickEconomy you can set your region to automatically stay the same on your profile page. Change your region...

Where do we get your set images from?

Most of our images are supplied by third party affiliates or via the LEGO website directly or via arrangements we have with various partners. While we do our best to make sure we are not publishing copyrighted materials there is a change we did so inadvertently.
