If you got here searching for “which LEGO to buy so it gains value”, we owe you the complete answer — the uncomfortable part included. There is a whole content industry that lives off telling you that retired sets “go up X% a year” and selling you lists of “the 10 best sets to invest in”. We maintain a database with thousands of sets, their retirement dates and their captured prices, and that is precisely why we are not going to tell you that story. This guide is what we would say to a friend asking us with their wallet in hand.
What is true (and why it is no use to you as a promise)
It is true that some retired sets later sell for much more than their original price. It is the part of the phenomenon everyone has seen: the discontinued set that costs double or triple on the secondary market. It exists, we do not deny it — in fact, it is the reason retirement dates matter and the reason this website exists.
What almost nobody adds is the three pieces of fine print:
First: it is a surviving minority. For every set that triples in price there are many that sell years later at the original price or below, before even accounting for inflation. The examples that circulate are the winners; the losers do not show up on the lists because nobody brags about them.
Second: costs eat the margin. Selling a sealed set years later is not free: platform fees, shipping a big, heavy box, the risk of damage (a dented corner sinks the value of a “collector” set), and the real cost of having hundreds of euros sitting idle in a wardrobe for years. The headline “+50%” ends up as considerably less net.
Third: the past is not a contract. Historical data describes what happened, not what will happen. The LEGO market of the next decade depends on LEGO’s decisions (will it re-release an iconic set? it has done so), on trends and on how many people bought exactly the same thing as you “to invest” — because ten thousand sealed boxes of the same set waiting for a buyer are, literally, future supply piled up against your sale.
What nobody can know (us included)
There is no serious way to predict which particular set will gain value or by how much. Whoever gives you a number is extrapolating from the past or making it up. That is why at LastChanceBricks we have a written editorial rule: we do not publish ROI, or projections, or “investment scores”. Our database knows what is retiring and what it costs today; it does not know the future, and we would rather be useful than look clever.
What can be said with data in hand are the factors that have historically set the survivors apart: sets with no natural successor (Ideas sets, collector D2C sets, licensed flagships), themes with sustained adult demand, and exclusive minifigures or part designs. They are the same criteria we use in our theme guides — but note the nuance: they help you decide what to buy before it retires if you want it, not to guarantee that you will make money.
The only scenario where “investing” makes some sense
To be fair, there is one profile for whom the game can work: someone who buys sets they would like to have anyway, with money they do not need, taking advantage of prices below the official one, in themes with adult demand — and who accepts that the most likely outcome is keeping them.
Notice the trick in that profile: their worst-case scenario is keeping a LEGO set they wanted, bought at a discount. They do not lose even if they “lose”. That is the only version of “investing in LEGO” that seems defensible to us, and as you will have noticed, it is indistinguishable from simply buying well.
The version we do not defend: going into debt or tying up significant money in boxes you are not interested in, chosen from an internet list, hoping to sell them to strangers five years from now. That is not investing; it is speculating in an illiquid market, with no data about the future, against people with more information than you.
How we buy (the boring method that works)
Buy what you want to build or display. It sounds like stating the obvious and it is 90% of the decision. A built set in your living room has given you value even if its market price never moves at all.
Use retirement as a calendar, not as an argument. The date a set leaves LEGO’s official list tells you when to decide, not whether to buy. Our retirement calendar exists for that: so that the set you have been eyeing for months does not slip away from you, not to rush you into sets you did not want.
Do not pay a markup on a live set. As long as a set is still on LEGO’s official list, paying above the LEGO.com price cannot be justified. On every set page we show the captured Amazon price next to the official one with its date: if Amazon is below, good; if it is above, LEGO.com or wait.
Be wary of the phantom discount. “Before 149.99€, now 99.99€” only means something if the 149.99€ was real. Our deals section only lists sets where the captured Amazon price is below the current official price — the only reference that cannot be dressed up.
And if you are going to speculate anyway: do it with the three pieces of fine print above in front of you, with money you can leave idle for years, and with sets you would be happy to unbox if the plan goes wrong. It is our only investment advice, and notice that it is really buying advice.
The sums nobody shows (an example with round numbers)
Let’s do the exercise the “invest in LEGO” videos never do, with deliberately hypothetical, round numbers to see the mechanics. Suppose you buy a 200€ set today and that four years from now it sells on the secondary market for 300€ — a scenario on the optimistic side.
Of those 300€, the selling platform takes its fee (say 10-15%: 30-45€). Insured shipping for a big box, another 10-20€ if you do not pass all of it on to the buyer — and if you do pass it on, your price competes worse. You are left with roughly 240-260€. The real gain on the 200€ invested comes to around 20-30% in total — over four years, that is, in the order of 5-7% a year. With the risk of a damaged box (goodbye sealed premium), the risk that that particular model does not go up, zero liquidity (try selling it in 48 hours if you need to) and your own work storing, photographing, listing and shipping.
Compare that profile with any boring, diversified alternative that does not force you to keep boxes in the storage room, and you will understand our position: retired LEGO can make money, but as a formal investment it competes badly as soon as you put the costs in front of it. As a smart purchase of something you want, on the other hand, it competes wonderfully — the whole “risk” is keeping what you wanted.
In short
Can you make money with retired LEGO? Some people have. Can you know in advance with which set? No, and whoever says otherwise is selling you something. What do we do with our own data? Use it to buy sets we want, at a good price, before they retire — and sleep soundly without checking market prices. We recommend exactly the same to you.
