Make lots of money by buying and reselling used LEGO!
This series of articles explores the practical economics of buying, sorting and selling bulk Lego. I will help assess what it takes to make real money by describing my own experience buying a large used Lego collection on Craigslist for a discounted price, figuring out what sets I had, sorting the bricks back into the original sets, acquiring the missing pieces and reselling for a profit. Along the way, I’ll call out some of the hidden costs and benefits for Lego enthusiasts.
LEGO as an investment?
Before I go deeper into the details of my project, I should point out that investing in Lego can be a big business for some folks. There’s an active community at brickpicker.com which helps people invest in Lego, although they focus on investing in unopened/new sets. On that site, you can see the current value of any Lego set (based on Ebay and other sources). It also allows you to record and track the value of your portfolio of Lego sets as if it were a stock market. I have purchased a couple Lego sets as a small-scale investment to support my hobby, but I don’t want to build up a large enough inventory to make it profitable.
A couple ways to make money selling Lego:
- Most people invest in unopened Lego sets, hoping to sell them in a couple years when they are no longer available for a healthy profit. (Some of the most sought-after sets have doubled in cost in just two years, and that isn’t accounting for the possibility that you may have initially purchased the set at a discount.)
- Some folks try to find sets at a discount and resell them immediately for a profit.
- Others buy used Lego bricks and sets and try to sell for a profit. (This is the focus of this article.)
What is Lego worth?
Before you buy anything, you need a basic knowledge about how much used Lego is worth. The following is a rough guide based on my experience:
- New Lego sets have a MSRP of between 8 and 12 cents per brick. That said, most sets can be purchased for between 10 and 40% off if you are patient, take advantage of rewards programs and sales. (Many of the large “Exclusive” sets which adult fans want are much harder to buy at a discount.)
- Used Lego sets in good condition are worth between 50% and 75% of retail prices while they are still available in stores. 6 – 12 months after they are no longer available, used sets usually catch up with MSRP, and can slowly increase in value if they are in high demand.
- The rule of thumb for unsorted Lego is between 6$ and 12$ per pound. If the bricks are sorted by color or include lots of desirable pieces, they are worth more.
- The value of Lego Minifigures varies greatly. Rare minifigures from a popular theme like Star Wars can sell for 5-10$ a piece. More common minifigures sell for about 1$.
- Selling individual used bricks on a site like bricklink.com can yield much higher prices, but it requires a small warehouse to store your bricks and seems like an unbelievable time commitment.
Based on these factors, I decided that buying a used collection containing older sets which I can sort into complete sets would be the best approach for me, especially if I could get it for a really low price.
Deciding what to buy
If you are looking to buy used Lego, you have a couple options: Ebay, Craigslist and Garage Sales to name a few… I prefer Craigslist as you don’t have to worry about shipping, and you can see what you are getting before making a payment. My goal was to buy a collection containing many sets which I could sort out and sell for a profit. I also hoped that the collection would include some themes which interest me. (In my case: Star Wars, Harry Potter, Lord of the Rings or Architecture.)
Buying a profitable collection:
I looked at dozens of used Lego collections on Craigslist listings before I made my first big purchase. I live in Seattle which has a lot of Adult Lego enthusiasts, so it’s harder to find a great deal here. Since I was traveling to the east coast for the holidays, I checked Craigslist in areas we were visiting and found some better collections for sale than anything I’d seen in Seattle.
The collection which I bought on Craigslist wasn’t very detailed and included only two blurry photos. The listing said that it included the “6211 – Imperial Star Destroyer” set which was released in 2006, plus “some other sets”. The original craigslist post is gone, so I can’t show you exactly what was listed, but I can say that the listing under-represented the size of the collection.
As the listing was a bit unclear, I sent the seller the following clarifying email:
“Are there any minifigures in the box? I am trying to determine if there are some nearly complete sets that are just missing instructions or not.”
As they say, it never hurts to ask! In response, I got a lot more info than they put in their original Craigslist post:
“There are mini figures in the collection as most of it came from sets. The sets were broken down and the boxes / instructions were thrown out.
Here are just a few that are in the container:
LEGO Star Wars Clone Turbo Tank (8098)
LEGO Star Wars General Grievous Starfighter (8095)
LEGO Power Miners Fire Blaster (8188)
LEGO® Power Miners Claw Catcher 8190
LEGO Power Miners Titanium Command Rig (8964)
That last one was $200 alone.. Obviously everything is broken down into 1 pile. Ie, they are not separated by set into ziplocks etc.”
Getting this much new information was great for me, since I had more information to help make a buying decision than other potential buyers. At this point I was confident that this would be a profitable purchase given the 150$ asking price. At the very least, I could resell the Imperial Star Destroyer to recoup my costs. I made arrangements to buy the collection, and was blown away by the two massive Rubbermaid bins which they game me. (This created two problems outside of the scope of this article: Figuring out how to get 60+ pounds of Lego back to my home in Seattle, and figuring out how to keep my wife from killing me for buying so much Lego on vacation!)
Tips and Tricks to buy the right collection:
I’m hardly an expert, but the following are some helpful tips to help make sure you get a good deal.
- Be patient. People sell used Lego collections every day. You need to find a great deal if you want to make any money.
- Ask questions. If the listing isn’t clear, ask for more details. If you want a photo showing which minifigures are included, it doesn’t hurt to ask. You can always ask for a lower price too, although be sure to close on a price before you make arrangements to see or buy the collection.
- Follow your interests. You are going to be spending a lot of time with these bricks, so it would be nice if the collection includes some sets that you are excited to build. Who knows, you might even decide to keep a couple sets as your “reward” for selling the others.
Next step: How to sort a lot of Lego…
In my second post, I explained the process I used to sort 60 pounds of LEGO into more manageable groups.

So how DID you get it back across the country?
I don’t usually resell used sets that I get this way, but I’ve bought a few lots this way for myself. One trick I’ve used is to save the Craigslist ad before I go to pick up the LEGO – that way I have their original description and photos to refer to after the fact.
@Dan, I borrowed a large suitcase and duffel bag from family. Thankfully we were flying Southwest airlines so we could check the bags for free!
I recently started buying Legos again after a 20 year sabbatical since middle school. I bought a few sets the last few years since I was married when I saw sales. Shortly before Christmas I bought several larger sets on sale including the Lego Creator Police Station. Then this Christmas my four brothers and I got all the Rubbermaid’s full of Legos from our childhood and built the 120 or so sets. Now the last few weeks I have been buying used Legos on Craigslist, ShopGoodwill and Facebook Marketplace. Wife is loving the cool Legos for our son but also not thrilled with the space they take. While my mindset on Legos is generally “never sell” there are themes that I don’t really want to keep and would sell if I got them for a good price.
It seems reasonable to sell anything you no longer want or need, including LEGO sets in themes that you are not attached to… Good luck!
I have TONS of Lego that my son has outgrown, and I am thinking of selling it. It is mostly Star Wars, Indiana Jones and Coast Guard (I think we had every set of the CG series). Plus hundreds of mini-figures. Should I sell by the pound? Regroup back into sets? I have almost all of the instruction booklets as well. Spent a small fortune on it, so would like to get the most return as possible…
@Allison, It is labor intensive to sort them back into sets, but it will give you a much better return than selling by the pound. It really depends on how much you value your time.
You might be able to do a little better than selling by the pound to sell the “complete lot” and clearly display the various manuals you have and the associated minifigures. You could also sell the minifigures separately, and then sell the rest by the pound.
It also seems like LEGO sells for better prices in different parts of the country. For example, In Seattle, used LEGO sells for nearly twice the cost than in Richmond, Virginia.
I’m about to have a yard sale. My brother wants me to help him sell his Lego’s, we are keeping the ones that are already together that way and selling them. However we have several loose Lego’s and no instruction books. How would you recommend selling them?
It is very time consuming, but sorting the LEGO bricks into the various sets, and acquiring any pieces which might have been lost will likely command the highest price. That said, this is probably not work it unless you enjoy sorting a lot of LEGO and building the sets one more time.
The next best thing to do is sell on Craigslist, and include a clear photo showing the sets included in the collection by photographing the instruction manuals.
Anyone has tried selling on oldlego.com? They claim to be fees free…
I would like to sell my sons old Legos. Right now we have 45lbs of Legos. They are all sorted according to color only. All sets have been broken up. There are also 150 mini figures. Most of the mini figures are common figures, but there are at least 20 popular mini figures from Star Wars, Harry Potter, Indiana Jones, Batman and etc. Having never sold something like this before, I am wondering how I should go about pricing the lot?
I have a new/ in box set of mars mission 7697. I’m trying to figure out how much it’s worth and where the best place to sell it would be. A little research has shown me that it was made in 2007. The box has been opened, but the plastic bags within have not and the directions are there as well. The condition of the box is excellent except for the fact that it was opened gently. I tried the brickpicker site, but received an error. Not sure if you have any answers for me or another site I can check? Thanks.
Sets which are opened but the bags are still sealed will sell somewhere between the “new” and “used” prices on bricklink.com if you sell the set on Ebay. It should sell for somewhere between 35 and 55$.
Great article! Just a few questions for you today, and thanks for your time. Have you ever been able to put together a set from a random bunch of Lego bricks you got, and does that set have resale value? My reason for asking is my son received a massive amount of bricks, some of the pieces look like they are from sets, but we’re not too sure which ones and what not… He’s hoping if he finds out what sets, he’ll be able to put them together and resell them whole. Is there a market for this? What’s the best way to find what sets he has from just a bunch of pieces? Will it matter he doesn’t have boxes or instructions, as long as he has the correct parts? And lastly, Where’s the best place for him to put them up for sale?
Thanks so much!
Look at the minifigures and the bricks with Stickers or printed logos, since they are the best way to guess what sets are contained within the larger box. It is extremely time consuming to sort out the used sets, but it is possible and the sets can be valuable if they are complete and in pretty good condition. Good luck!
We have a huge (half closet size) tote full of Legos. A great deal of them came from a family friend, just as-is, random box of Legos. We added several full sets to the box since then. I have instruction manuals for all of them. Sadly, my son took a bunch of the Minifigures to school for a project or activity and failed to get them back from his teacher. (They are not recoverable at this stage) How much would this effect the resale of the sets? We also have lots of random guns and accessories we have sorted out. Would it still be worth it to me rebuild the sets without all the minifigures?
without the minifigures, the “sets” would not be worth much, so it is probably not worth your time. Your best best is to either keep to build with, or sell as a bulk lot.
Are Craigslist, Ebay and Etsy the only resale sites for Legos? I’m kinda looking for a site that picks up my used sets, prices them then sends me a check. Does this exist?
BrickLink is a lego-centric site, but not really for selling bulk. They don’t work on consignment or like Cash For Gold however.
Nope no places like that
I have an almost complete set of LEGO Cafe Corner (Café Corner) 10182 Modular Building, which i was shocked to find selling unopened for over $3k on ebay. I can’t seem to find the tower or the Hotel sign, which are probably key pieces, but I could probably dig around a bit and they may turn up. Do you think there is any value in trying to sell what I do have, and if so how could I set a price?
I have been sitting on my stepsons Legos for 8 years now. I know for sure that I bought him. Indiana Jones, Café Corner, Pirates of the Caribbean, 3 different Star wars and all the Bioniocle characters between 2007 and 2010. The collection is a total of 1998 through 2012. Easily 150 lbs. unsorted, 20lbs sorted by size. 200 mini figures, 20 action figures, 20 vehicle’s, 20 airplanes, 20 space vehicle’s, 10 dinosaurs, 10 dumpsters, cranes, backhoes. A Military set with trucks, tanks and boats that I cant find on line. All These made and in whole. When we moved in 2010 out of our house both my step son and his dad refused to box up the upstairs play room off the hundred’s of Lego sets. I told them both that when I sold them they would SORRY. Well I am over whelmed. Thank god I found this site that gave me a clue as how to proceed. I am going to put on line through Craig’s List in the next week and will post on this forum how to get to it.
I have alot of Lego divided in colors
I have approx 60 lbs of legos, generally sorted by color. Lots of characters. Star wars, harry potter, etc. etc. Instruction pamphlets. Misc box of wheels, etc. Collection from two boys over many, many years. How do I sell?
There is no easy answer – you will make more money if you sort into complete sets, but it is a lot of work. If you want to get pretty good money at low effort, list it on craigslist or ebay with photos of all the instruction manuals. Be clear that you should have most of the parts, but some stuff may have gotten lost over the years.
I have just over 100 Lego figures, they’re very mismatched. In order to sell them do I have to somehow reassemble them to their original self or would somebody buy them ‘as is’.
someone will purchase minifigures as-is, but you would get less than if you assemble them correctly.
Hello, I am wondering how much to sell my Lego Architecture sets for? I have 18 different sets with the boxes and instructions and all the pieces are there. I have put them together once or twice. They are in good condition. Plus some of the sets are retired. Can you give me a suggested price. I have had people offer $20 bucks for 18 different sets and I think that is too low of price.
Just do your research, and sell sets for a fair price. Used sets are definitely worth less than new ones.
Hi Mr. Alphin, My 11 year old son and I just discovered your website. It is awesome! Thank you for providing so much useful information! We have a giant Rubbermaid container of bulk Legos. Thank God I had the forethought to keep all the instruction manuals from over 150 sets. Your posts have given us the motivation to finally sort and sell!
Hi, I have a few questions regarding this article. This all sounds great however what do you do without the instructions? Also how do you resell this without the box and instructions. Finally what profit did you make / how much did you resell the star destroyer without the box and instructions regards
What is better? Selling a lot of sorted legos and manuals? Or putting the sets together to sell?
I have a whole room full of bulk Lego to sell. Just looking for the best price. My son has outgrown it. He had so many sets I can’t even estimate how many…including the Death Star which has a few pieces mixed in with the bulk mix.
Hello Tom Is it worth the effort to print up instruction books on line is there enough of a value increase to warrant the time effort
I found helpful guide here thank you for this article
I have at least 80 pounds of Legos I bought for my Grandson some time ago. They are all in a 60 gallon bin. As I got them from a rummage slae. Since then my Grandson as past away & I would like to sell them. What should I do? They are all mixed togehter in a BIG bin. Haven’t really looked through it. But should I seprate by color & figures? Very confused!
I have about 15 already built collection of star wars, mostly the Clone wars. I do not have box or instructions. I also have about 50 or more figurines, including 31 storm troopers. I have no idea their worth, or how to sell them. I also have about 70 pounds of colour sorted lego. Any help would be greatly appreciated.
LEGO recently publicized a program to donate used bricks — see https://www.lego.com/en-us/campaigns/replay
It’s simple — you print a FedEx label at home, box up your pieces, and send them off.
My question is … how would I approximate a value for tax deduction purposes? I assume per pound?
Very helpful information in your article, Tom, thanks!
Joe R., thanks for the donation link too!
l buy legos, in NJ for cash
bulk, $3 per pound,
more if brick or color sorted, OR in sets
prefer starwars lots
do not buy unopend box sets.

STOP PLAYING GAMES
hi i want to sell a half built lego set. can i sell it half built?
I go to see every day a few web pages and sites to read posts,
except this weblog offers quality based articles.
Excellent blog you have here..
It’s hard to find good quality writing
like yours these days. I really appreciate individuals
like you! Take care!!
Good way of describing, and pleasant
to get data concerning my presentation focus, which i am going to deliver in academy.
First off I would like to say terrific blog!
I had a quick question in which I’d like
to ask if you do not mind. I was interested to find
out how you center yourself and clear your thoughts
before writing. I have had difficulty clearing my mind in getting
my thoughts out there.
I do enjoy writing however it just seems like the first 10 to 15 minutes tend to be lost just trying to
figure out how to begin. Any suggestions or tips?
