How Much Is My LEGO Set Worth?

A LEGO set is worth what people are actually paying for it right now, which depends on its condition (sealed, used, or incomplete) and on whether you look at asking prices or completed sales. The reliable number to trust is the recent sold price for a set in your condition — and retired sets still sealed in the box (NISB) usually command the most.

There are three figures worth understanding before you check.

New vs used: what's the difference in value?

A sealed, never-opened set is worth far more than the same set used. "New" means factory-sealed; "used" means opened, whether built or in pieces. Always compare against the matching condition — a used set priced against sealed listings will look like a bargain that isn't.

Why is the sold price more reliable than the listed price?

Anyone can list a set at any price; that doesn't mean it sells. The number that matters is what sets have actually sold for recently. Listed prices tell you the ceiling sellers are hoping for; sold prices tell you the real market.

What is part-out value?

"Part-out value" is what a set would fetch if you broke it up and sold every piece and minifigure individually. It's often higher than the set's used price, which is why people part out sets — but it assumes you're willing to list and ship dozens of small lots over time. For most collectors the used set value is the practical number; part-out value is a ceiling for sellers with the patience to realise it.

The usual ways to check

• Marketplace "sold" filters — searching completed listings gives real sold prices, but you do it one set at a time and have to filter by condition yourself.
• Price-guide websites — handy averages, but you're looking them up in a browser, separate from your own collection.
• Guessing from the box price — the original retail price tells you almost nothing about current value, especially for retired sets that have appreciated.

The easy way: see market values in Afolio

Afolio shows market values for the sets in your collection without leaving the app. Select a set and Afolio pulls current pricing and shows:

• New and used values side by side
• Listed and sold prices, with average, median, minimum, and maximum
• The underlying sales and listings from BrickLink, so you can see the actual transactions behind the averages
• Price forecasts and growth rates, so you can see whether a set is trending up PRO

Because every set you own is already in Afolio, you get a value next to each one instead of looking them up individually — useful for insurance, for deciding what to sell, or just for seeing what your collection is worth. You connect your own pricing API keys, which are stored locally in your Mac's Keychain, never on a server. Afolio prices at the set level; part-out value is a concept to weigh up separately, not a figure the app calculates.
