The short version
- Typical range: £10 – £200 — see the full LEGO sets value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price

Before you photograph it
Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.
- Identify the set number, which is printed on the box, the instruction booklet and often in online piece guides.
- Sort and count the pieces against the parts list if you can, or state honestly that it is unchecked.
- Check whether the instructions, box, minifigures and any stickers are present, since each affects the price separately.
The photographs that sell LEGO sets
Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.
- The set built, or the sorted pieces laid out
- The minifigures lined up together
- The instruction booklet and box, if present
- Any missing, damaged or discoloured pieces
Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.
Writing the title and description
Set number and name first: “LEGO 75192 Millennium Falcon UCS, Complete with Instructions and Box”. The set number is exactly how collectors search. State completeness plainly — complete, complete with box, or incomplete with a piece count — because that is the price band.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Set number and official set name
- Whether it is complete, and if not, roughly what is missing
- Which minifigures are included, named individually
- Whether instructions, box and stickers are present, and whether stickers are applied
What buyers will actually ask
You will receive the same three messages about LEGO sets. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.
Check against the parts list if you can, and if you cannot, say it is unchecked rather than claiming complete. Collectors verify and remember.
Name each one. Minifigures are frequently worth more than the bricks and are the first thing buyers count.
Say so. Unapplied sticker sheets are worth meaningfully more to collectors, and applied ones are normal for played-with sets.
Pricing it so it actually sells
Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.
The LEGO sets value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.
What you keep, compared
On a £105 sale — roughly the middle of the range for LEGO sets — here is what the commission-charging platforms would take, and what you would keep on each:
| Where you sell it | Fee | You keep |
|---|---|---|
| WishThrift | £0 | £105 |
| Poshmark | −£21 | £84 |
| eBay | −£14 | £91 |
| Mercari | −£10 | £95 |
| Etsy | −£7 | £98 |
Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.
Timing and getting it to the buyer
Strong year round with a sharp Christmas peak. Retired sets appreciate and sell quickly; current sets compete with retail discounts.
Heavy for their size and expensive to post in quantity — weigh before quoting. Bag pieces by colour or step to make the parcel manageable and the buyer’s life easier.
WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions
How do I find a LEGO set number?
It is printed on the box front, on the instruction booklet cover, and can be identified from the build itself using online set databases. It is the single most important detail in a LEGO listing.
What are used LEGO sets worth?
Typically £10 to £200, with retired and licensed sets far above that. Completeness, minifigures and the box drive the price. See the LEGO sets value guide.
Is incomplete LEGO worth selling?
Yes. There is a strong market for bulk bricks by weight and for individual minifigures. Just be explicit that the set is incomplete rather than hoping the buyer will not count.
