There comes a day for almost every LEGO® fan when the storage boxes win. Maybe a collection outgrew the shelf, maybe the kids moved on to other things, or maybe you simply want to free up space and turn old bricks into something useful. The problem is rarely deciding to sell. It is figuring out what your LEGO is actually worth and where to sell it without getting lowballed or buried in admin.
This is an honest overview. We sell and buy LEGO every day at CrocoBricks, so we know the trade-offs of each channel, and we are not going to pretend our way is the only way. Below you will find what drives the value of your bricks, an honest comparison of where to sell LEGO, and how to do it with the least hassle.
What is your LEGO actually worth?
"What is my LEGO worth?" is the first question everyone asks, and the honest answer is: it depends on what you have. LEGO value is not one number. It is the sum of three quite different things, each priced in its own way.
Sets, parts and minifigures are valued separately
A sealed or complete set is valued as a whole, often against what collectors pay for that specific set number. Loose parts have a value per element, driven by how in-demand that mould and colour are with builders. And minifigures are their own market entirely, where a single rare figure can be worth more than the large set it came in. The practical takeaway: a mixed collection is almost never worth "X euros per box." It is a set value, plus a parts value, plus a minifig value, added together.
Condition, completeness and rarity
Three factors move the price within each of those categories. Condition: clean, undamaged bricks beat yellowed, bitten or scratched ones. Completeness: a set with all its parts, instructions and box is worth far more than the same set missing a third of its pieces. (If you are buying rather than selling and need to complete a set, our guide on LEGO missing pieces covers that side.) Rarity: retired sets, discontinued colours and limited minifigures carry a premium simply because supply dried up. A common grey plate from a current set is worth cents; the same shape in a retired colour can be worth real money.
"Per kilo" is the floor, not the ceiling
You will see LEGO sold and bought by weight, and there is nothing wrong with it. Selling LEGO by weight is fast and simple, and for a big tub of mixed, common bricks it is often the most sensible route. Just understand what it is: a price-per-kilo figure treats every brick the same, which means it is essentially the floor price for bulk. If your collection hides a retired set, a sought-after minifigure or a stack of rare parts, weighing it all together leaves money on the table. Per kilo is a fair baseline for the ordinary stuff, not the right tool for the gems.
Where can you sell LEGO? Your options compared
There is no single "best place to sell LEGO." The right channel depends on how much time you want to spend, how fast you want the money, and how much you care about squeezing out the last euro. Here is an honest look at the main options.
Marktplaats, eBay and Vinted
The big general marketplaces are where most people start, and for good reason. You set your own price, you reach a huge audience, and on a good day you can get close to full collector value. The trade-off is effort and time. You photograph and list everything, answer questions, deal with hagglers and no-shows, handle shipping or local pickup, and wait for the right buyer. For a single desirable set or a standout minifigure, that effort can absolutely pay off. For ten boxes of mixed bricks, it becomes a second job.
BrickLink and Brick Owl
BrickLink and Brick Owl are the specialist marketplaces built for LEGO, and they are brilliant if you want maximum value for parts and minifigures. Buyers there know exactly what they want and will pay fair prices for the right element in the right colour. The catch is that they reward sellers who inventory carefully: you sort, identify and list parts down to the element and colour, manage a store, and pack many small orders. The potential return is high, but so is the workload. If you enjoy the cataloguing side, this is your home; if you do not, it is a lot.
Selling to a reseller (such as CrocoBricks)
Selling to a reseller flips the priorities: you trade a bit of top-end value for speed and simplicity. Instead of listing, chatting and shipping dozens of times, you get one offer for the lot and one payout. You do not sort, you do not run a store, and you do not chase buyers. The honest trade-off is that a reseller has to leave room to grade, sort and resell, so a single rare set might fetch more if you list it yourself. For whole collections and mixed bulk, though, the time you save is often worth more than the last few percent.
Here is the honest at-a-glance comparison:
| Option | Effort | Speed | Potential return | Best for |
|---|---|---|---|---|
| Marktplaats / eBay / Vinted | High | Slow to medium | High (single items) | Standout sets & minifigs |
| BrickLink / Brick Owl | Very high | Slow | Highest (parts & minifigs) | Sorted parts, dedicated sellers |
| Reseller (e.g. CrocoBricks) | Low | Fast | Fair, all-in | Whole collections & bulk |
How to sell used LEGO without the hassle
Whichever route you choose, a little preparation gets you a better, faster offer. You do not need to do all of it, but the more you know about what you have, the smoother things go.
A few simple sorting tips
Start by separating the three value groups: complete sets in one pile, minifigures in another, and loose bricks in a third. Note down set numbers if you have boxes or instructions, since the number is what a buyer prices against. (If a part is a mystery, our guide to finding LEGO part numbers helps you put a name to it.) Give grimy bricks a gentle wash and let them dry fully. Pull aside anything that looks rare or unusual, and double-check that it is genuine, especially with minifigures, where our guide to spotting fake minifigures is worth a read before you sell.
When bulk beats selling piece by piece
The rule of thumb is simple. Items with clear individual value (a retired set, a sought-after minifigure, a rare part) are usually worth listing on their own. Everything else (the mixed bricks, the incomplete sets, the random tub from the attic) is almost always better sold as a single bulk lot. Trying to list five thousand common pieces one by one is how a sell-off turns into a year-long chore. Sell the standouts individually if you have the patience; let the bulk go as bulk.

Frequently asked questions
What is my LEGO worth?
It depends on what you have. Sets, loose parts and minifigures are each valued in their own way, and condition, completeness and rarity then move the price up or down. The simplest way to find out is to send us photos or a list and get a free offer.
Do you buy loose parts or only complete sets?
Both. We buy complete sets, loose parts, individual minifigures and entire mixed collections. You do not need everything boxed or sorted to get an offer.
Should I sell per kilo or per set?
Common, mixed bricks are usually fine to sell by weight; that is a fair baseline for bulk. Standout sets and rare minifigures are better valued individually, because weighing them in with everything else undersells them. When you send us a collection, we look at both so the gems are not lost in the bulk.
Does my LEGO need to be complete or in the box?
No. Complete sets with boxes and instructions are worth more, but we also buy incomplete sets and loose bricks. Just tell us honestly what is there, missing pieces and all.
How do I get an offer?
Send a few photos or a rough list through our sell your LEGO page. We will come back with a fair, no-obligation offer.
