Who Buys LEGO Collections in the UK?

If you have a sealed LEGO collection to move, there are fewer serious buyers than the internet makes it look, and they are not interchangeable. This is a straight description of each type, including where we fit and where we do not.

Specialist retired-LEGO retailers

Businesses whose whole trade is sealed, discontinued sets. This is what we are. A specialist can price a collection line by line because they already know what each set sells for and how quickly, which means they can take the awkward middle of a collection as well as the headline boxes.

• Usually the best price for a whole sealed collection, because nothing is being guessed at.
• Will normally take the lot rather than picking out four sets.
• Should be able to give you a figure from a list, before anybody travels.
• Will not want opened sets, built models or loose bricks. That is a different trade.

General second-hand dealers

House clearance firms, general resellers, the sort of business that buys whatever is in the garage. Genuinely useful if your collection is mixed with other things you want gone, and they will often take the lot in one van.

The trade-off is pricing. A dealer who does not specialise in LEGO cannot know that one unremarkable-looking box is worth more than the ten around it, so they price defensively across the whole pile. That is rational of them, and it costs you.

Other collectors

Often the highest price per set, on the specific sets they want. The catch is that a collector wants the four boxes they have been chasing, at a good price, and has no interest in the remaining sixty. If you sell that way you have taken the easiest money out of the collection and made what is left harder to move as a lot.

Auction houses

Worth considering for a genuinely rare single set. For a general sealed collection the fees, the timescale and the uncertainty rarely work in your favour, and you carry the risk of a quiet room on the day.

The five questions that actually separate them

1. Will you price it from a list before anybody travels, and does that price then stand?
2. Do you take the whole collection, or only the parts you want?
3. Who pays to move it, and who carries the risk while it is moving?
4. When am I paid, and by what method?
5. What happens if one box is not quite as I described it?

How we answer those five

A word on shelf wear

People often apologise for their boxes before they have even sent a list, and it is usually unnecessary. A bit of shelf wear on a sealed box is normal for a set that has been on a shelf for eight years. It is not a problem and it does not need hiding.

What matters is that the list matches the boxes. Tell us the worst one and we will price for it. The version that goes wrong is the one where a collection described as mint turns out to have a crushed corner on the biggest set, because then somebody has to re-open a conversation that was already settled.

Should you get more than one offer?

Yes, and any buyer worth dealing with expects it. If somebody discourages you from getting a second figure, that tells you something. What is worth comparing is not just the number but what it comes attached to: who pays the transport, when the money lands, and whether the figure survives contact with the boxes.

What we do not buy

Sealed and unopened only. Not opened sets, not built models, not loose bricks by weight, not boxes with pieces missing. Those are real markets with real buyers, they are just not ours, and we would only be guessing at the value. If part of your collection is opened, say so and we will be straight about which part we can price.
