No, piece count alone does not reliably predict what a LEGO set is worth when you part it out. A 2,000 piece set built almost entirely from common bricks can part out for less than a 400 piece set that happens to include a couple of sought after minifigures or a handful of rare printed elements. Piece count tells you how much plastic you are holding. It does not tell you what buyers actually want to pay for it.
I get asked some version of this question constantly from sellers who are staring at a pile of sets trying to decide what to break apart and what to sell whole. In my experience running the numbers on hundreds of sets, the "more pieces equals more money" assumption is one of the most expensive myths in LEGO reselling. It leads people to part out sets that would have sold better whole, and to keep sets intact that were quietly worth a lot more in pieces.
- Piece count is a weak, standalone predictor of part out value.
- Minifigures, rare colors, printed parts, and retired status usually matter more than raw piece totals.
- Price per piece varies wildly between sets and even within the same theme.
- Common bulk pieces (basic bricks, plates, small parts) drag average value per piece down fast.
- A simple checklist beats guessing when you are deciding whether to part out or sell a set whole.
Why Does the Piece Count Myth Persist?
Sellers assume more pieces means more value because that is how sets are priced brand new. LEGO prices sealed sets roughly by piece count, part complexity, and licensing, so it feels natural to carry that logic into the resale and part out world. It breaks down once a set is opened, because now every individual part competes in its own micro market instead of one bundled retail price.
When I started sorting bulk lots, I made this mistake myself. I'd grab the biggest box in a lot assuming it was the best deal, and I'd walk past a smaller box that turned out to have three minifigures worth more than the entire big set combined. I've seen this play out over and over with sellers who are new to bulk buying.

What Actually Determines LEGO Part Out Value?
Part out value comes from what specific pieces are worth individually, not how many pieces exist in total. The biggest drivers are minifigures, rare or discontinued colors, printed and specialty elements, exclusive molds tied to popular themes, and whether the set is retired. A set can have a small piece count and still part out for real money if even a few of those pieces are in demand.
Here is a quick way to think about the hierarchy of what moves the needle:
| Factor | Typical Impact on Part Out Value |
|---|---|
| Minifigures included | Highest impact, especially licensed or exclusive figures |
| Rare or retired colors | High impact on specific elements |
| Printed or specialty parts | Moderate to high, depends on demand |
| Total piece count | Low impact on its own |
| Common bricks and plates | Very low value per piece, sold mainly in bulk |
Do Bigger Sets Part Out for More Money Than Smaller Sets?
Not automatically. A bigger set usually means more raw material and a higher bulk weight, but most of those extra pieces are common bricks, plates, and basic elements that sell for fractions of a cent each on their own. A smaller set with one or two valuable minifigures or a rare printed part can outproduce a much larger set that is mostly filler pieces.
I personally weigh a set by what I can identify inside it before I ever think about the box's piece count on the label. A 300 piece set with a retired Star Wars minifigure can beat a 1,500 piece City set every time, because City is one of the least liquid themes for minifigure resale. From what I've tracked, City figures rarely sell for more than a couple dollars each, while a single desirable Star Wars or Marvel figure can be worth many multiples of that.
How Much Do Minifigures Change the Math?
Minifigures are usually the single biggest swing factor in part out value, sometimes accounting for the majority of what a set is worth once broken apart. A set with a handful of well chosen minifigures can be worth parting out even if the rest of the build is unremarkable, because collectors buy figures for the character and story attached to them, not just the plastic.
This is why I always sort minifigures out first and evaluate them separately using brick'em's LEGO minifigure database, which currently tracks 18,686 individual minifigures, before I even look at the rest of the pieces. A minifigure that is roughly two thirds the size of an index finger can be worth hundreds, and in rare cases thousands of dollars, while the bricks around it in the same box might be worth pennies each. That gap is exactly why piece count on its own tells you so little.
What Is the Price Per Piece Myth?
The price per piece myth is the idea that you can estimate a set's part out value by taking an average dollar figure per piece and multiplying it by the total piece count. It fails because value is not distributed evenly across a set. A handful of pieces might carry almost all of the value while hundreds of others are worth close to nothing individually.
I found this out the hard way early on, back when I tried to build a simple spreadsheet formula based on piece count alone. It consistently overvalued big basic sets and undervalued smaller specialty sets. Averages hide the outliers, and in LEGO part outs, the outliers are usually where the real money is. If you want a more realistic estimate before you commit to breaking a set apart, running it through brick'em's LEGO collection value calculator gives you a far better picture than a piece count formula ever will.
Which Themes Part Out Better Than Others, Regardless of Size?
Theme matters more than size when you're deciding what to part out. Star Wars, Marvel, and Ninjago tend to be highly liquid and part out well because of broad, ongoing character demand, while City is generally illiquid for minifigure resale no matter how large the set is. Castle and Pirates sets, meanwhile, can surprise sellers with strong prices from nostalgic collectors even though those themes move slower.
In my experience, Modular Buildings are one of the more underrated categories for part out and whole set value alike. They require more capital to get into, but the individual specialty pieces and rare colors used in modulars tend to hold value well over time. On the flip side, I would not go out of my way to part out a City set expecting a big payday. Sort by theme demand first, then look at what specific pieces you're holding.
How Do I Evaluate a Set Before Deciding to Part It Out?
I run through the same short checklist every time before deciding whether to keep a set whole or break it apart. It takes a few minutes and it has saved me from parting out sets that were actually worth more intact, and from selling whole sets that were worth far more in pieces.
- Pull every minifigure and check it individually before touching anything else.
- Look for retired or discontinued colors, especially in less common elements.
- Check for printed tiles, printed bricks, or specialty molds tied to a popular license.
- Note the theme. Star Wars, Marvel, and Ninjago tend to part out better than City.
- Estimate bulk value for the leftover common bricks separately from the standout pieces.
- Compare your estimated part out total against what the set sells for whole and sealed or used.
If you'd rather not do this math by hand for every box in a haul, brick'em's haul calculator is built specifically to help resellers run this comparison across an entire lot at once, not just one set at a time.

Is It Ever Better to Sell a Set Whole Instead of Parting It Out?
Yes, and it happens more often than new sellers expect. If a set is complete, in good condition, and the theme is desirable, buyers will frequently pay more for the convenience of a complete build than the sum of its individual pieces would bring after fees, listing time, and shipping small parts. Parting out takes real time, and that time has a cost even when it does not show up on a spreadsheet.
I recommend sellers think about their own hourly value when they make this call. Listing forty individual minifigures on BrickLink takes far longer than listing one complete set on eBay or Whatnot. A lot of sellers I know underestimate that time cost and end up making less per hour parting things out than they would have made selling in bulk or whole.
Where Should You Sell Parted Out Pieces and Minifigures?
Where you sell depends on what you pulled out of the set. BrickLink is generally considered the pricing backbone of the LEGO resale world, sometimes called the Wall Street of LEGO because of how standardized its pricing data is, which makes it a strong fit for individual parts and low dollar items that would not justify shipping costs on other platforms. eBay puts items in front of a much broader audience, though promoted listings can push your effective take rate close to 25 percent of the sale on competitive items.
Whatnot has become a strong option for higher demand figures and small lots sold live, particularly in categories with loyal fan bases like Star Wars and Marvel. When I sell live, I've found that spending a modest amount, often cited around 20 dollars per show, on boosted promotion near the start of a stream can meaningfully help early visibility. None of these platforms are universally best. I match the platform to what I actually pulled from the set.
Fees matter just as much as audience size when you're comparing where to list. eBay's total take rate on a typical sale lands around 13.25 percent before any promoted listing spend is added on top. BrickLink runs closer to 3 percent plus standard PayPal processing, which is part of why it works so well for cheap individual parts. Mercari charges sellers around 10 percent. None of these numbers are fixed forever, so a lot of sellers I know double check current fee schedules before assuming last year's math still applies.
How Should I Price the Pieces I Decide to Sell?
Price against real, current sold data rather than list prices or piece count formulas. Marketplace pricing data changes over time as supply and demand shift, and a figure that sold for a certain amount a year ago may be worth meaningfully more or less today, especially for retired sets. Always check current sold listings before you commit to a price.
I personally check pricing tools that pull from BrickLink data before listing anything I'm unsure about, since guessing on price is how sellers either scare away buyers or leave money on the table. If you're building out an actual inventory rather than a one time lot, brick'em's blog has more breakdowns like this one on specific categories worth tracking closely.
Frequently Asked Questions
Does a higher piece count always mean a set is worth more to part out?
No. Piece count measures volume, not value. A large set built mostly from common bricks and plates can part out for less than a smaller set containing even one or two desirable minifigures or rare printed parts, since those specific pieces usually carry most of the value.
What single factor affects part out value the most?
Minifigures typically have the biggest single impact. Because they carry character and story value on top of their plastic value, a set with strong minifigures can outperform a much larger set with none, regardless of how many total pieces either set contains.
Are common bricks and plates worth parting out at all?
Usually only in bulk. Individually, basic bricks and plates sell for fractions of a cent, so they rarely justify listing one at a time. Most sellers group them into bulk lots by color or type rather than trying to sell each piece separately.
Is City one of the worst themes to part out?
For minifigures specifically, yes, in most cases. City figures rarely command strong resale prices compared to licensed themes like Star Wars or Marvel. The parts and vehicles from City sets can still hold some value, but the minifigure resale angle tends to be weak.
How can I estimate part out value before I break a set apart?
Start by identifying every minifigure and any rare or printed parts, then compare that against current sold pricing data. Tools like brick'em's LEGO collection value calculator can speed this up so you're not manually pricing every single piece by hand.
