How it works

No sorting, building or counting needed. We do the work.

    Within 24 hours we send an offer, with an explanation of how we got there. You're not committed to anything.

  3. We pick it up

    If you say yes, we agree on a time. We take a quick look at your place and pay you straight away.

Which photos help most?

What we buy

Mostly sets and minifigures. Built, taken apart or still in the box, it doesn't matter.

  • Complete sets

    With or without the box, built or in pieces. Instruction booklets and the original box raise your offer.

  • Nearly complete sets

    A few pieces missing? No problem. We work out what it costs to complete the set and only deduct that.

  • Minifigures

    We value every figure separately. Some are worth more on their own than you'd expect, such as many Star Wars, Harry Potter and older figures.

  • Boxes and tubs of loose LEGO

    Interesting when there are minifigures or recognisable sets mixed in. Loose bricks only, we sometimes buy. Send a photo and we'll tell you honestly.

  • New, sealed sets

    Still in the sealed box? We're happy to buy those, also when it's several sets.

  • What we don't buy

    Knock-off brands (such as Lepin, King or other copies) and LEGO that is broken, melted or badly discoloured. Not sure? Send a photo, we're always happy to take a look.

How we work out your offer

No guessing from one photo of a tub. For every set and every minifigure, we look up what it currently sells for second-hand in the Netherlands and Europe. Then we look at four things:

Every offer comes with an explanation. Want to know exactly how we got to a number? Just ask and we'll show you.

Completeness
Are pieces or minifigures missing, and what does it cost to complete them?
Box and booklets
A set with its box and booklets is clearly worth more than the same set without.
Condition
Scratches, discolouration, missing stickers or a damaged box all count.
Our work and risk
We check everything, clean it, complete sets and resell them. That takes time, and sometimes a set turns out not to be complete after all.

How to make your LEGO worth more

  • Keep the instruction booklets and boxes, even if they're a bit worn.
  • Keep minifigures with their set, if you know which goes where.
  • Please don't clean it yourself with hot water or cleaning products. We'll do that.

Which photos help most?

The better we can see what you have, the sharper our offer. This helps:

  • One overview photo of everything together.
  • The minifigures side by side, photographed from the front.
  • Boxes and instruction booklets, if you have them.
  • Set numbers, if you know them. They're on the box and the booklet.
  • For a tub of loose LEGO: how full it is, or its weight. A bathroom scale is fine.

Don't know something or short on time? Just send what you have, we'll ask if we need more.

About Stackback

Stackback was founded by two LEGO fans from Amsterdam. We buy LEGO that's gathering dust at home, check it, complete the sets and pass them on to new builders.

You get your space back, and your LEGO gets played with again instead of sitting in a box.

Frequently asked questions

How much is my LEGO worth?

It varies a lot. A tub of loose bricks usually isn't worth that much, while a complete set or a sought-after minifigure can be worth surprisingly more. That's why we look at every set and every figure. Send photos and you'll know within 24 hours.

Do I need to sort or build everything first?

No. Built, taken apart or mixed in a tub is all fine. Sorting and checking is our job.

What if pieces are missing?

That's completely normal. We work out what it costs to complete the set and factor that into our offer.

Am I committed to the offer?

No, our offer comes with no obligation and is valid for seven days. On our side, the offer stands as long as the LEGO matches the photos. If we see big differences at pickup, such as missing minifigures, we'll tell you honestly and you can still say no.

Why don't I get the full price I see online?

Online prices are what someone eventually gets after a lot of work: checking everything, taking photos, writing listings, talking to buyers and shipping. We take over that work and the risk, and pay you straight away. If you want the maximum and have the time, you can also sell it online yourself.

What do you do with my LEGO?

We check and clean everything, complete sets where needed and sell them on to other builders and collectors.

Do you pick up outside Amsterdam?

For now we pick up for free in Amsterdam. Live nearby? Message us anyway, for a nice collection we're happy to come by.

How do you pay?

Straight away at pickup: cash, by Tikkie or by bank transfer. Your choice.

Do you buy other toys or other building bricks?

No, only genuine LEGO. We don't buy knock-off brands.

What happens to my photos and details?

We only use your photos and phone number for your offer and the pickup, and never share them. If there's no deal, we delete the conversation within 3 months. More in our privacy statement.
