How to buy (and value) used LEGO sets

Retired sets are where the value is. Once LEGO discontinues a set, supply stops but demand keeps rising, so retired sets, especially large or licensed ones, often appreciate. If you are buying to build, a used or open set is far cheaper than a sealed one; if you are buying as an investment, a sealed, undamaged box is what commands the premium.

Completeness is everything on used sets. A used set should ideally come with the instructions and, for value, the original box, but the critical thing is that all pieces and minifigures are present. Missing minifigures hit value hardest because rare figures trade separately for significant sums. Ask the seller whether the set has been checked against the parts list, and treat "90% complete" as a discount, not a bargain.

Minifigures often out-value the bricks. Sought-after minifigures from Star Wars, Harry Potter and collectible series can be worth more than the rest of the set combined. If a listing bundles rare figures, that is where the real value sits, so check which figures are included and their going rate.

Sealed vs opened pricing. A sealed set typically carries a 20-40% premium over the same set opened but complete. For builders that premium is wasted money; for collectors it is the whole point. Match what you are paying for to why you are buying.

Common questions

Cheapest by model, at a glance

A daily snapshot of the lowest genuine eBay price for every model we track, and how good that price is right now versus its usual level, updated automatically. Prices last refreshed 22 September 2026 . Tap a price to see that model's cheapest listings on eBay, or tap a model name for the full live list here.

Under each model is the actual listing that price came from, so you can see whether it is the thing you want or a bundle, a variant, or an accessory that happens to share the name.

"Off retail" compares today's used price with what the model costs new. For anything still on sale that is its current new price, so the figure is close to a discount you could really get. For anything no longer sold it is the last new price we have on record: on a boxed product like a LEGO set or a console that is the RRP, and on a part like a graphics card it is nearer what new stock was going for at the end than what it cost at launch. So on older hardware read it as depreciation against late retail rather than against the original sticker. A few rows read "above" instead: they cost more used than new, which is normal for a retired set or a part nobody makes any more.
