LEGO Alien Conquest and Space Police minifigures still show up in bulk lots and old bins all the time, and yes, some of them are worth real money. In my experience the value swings hard based on which alien or officer you have, whether the printing and accessories are intact, and how patient you are about where you sell. Alien Conquest ran as a theme from roughly 2011 to 2012, and Space Police had its most recent wave from about 2010 to 2013, so both are solidly retired at this point, which is usually when resale value starts to firm up.
I've sorted through enough alien and space cop minifigures at this point to know the honest answer isn't "they're all valuable" or "they're all junk." It's somewhere in between, and it depends on specifics I'll walk through below. If you're trying to figure out what's sitting in your bin, or you're sourcing a lot that has a few of these mixed in, this guide covers what actually moves the price.
- Alien Conquest and Space Police are both retired, which supports long-term value, but individual figure prices vary widely.
- Condition, completeness (weapons, accessories, printed parts), and packaging all affect what a figure actually sells for.
- BrickLink is the best source for checking current market pricing before you buy or sell.
- Whatnot and eBay tend to move these figures faster than BrickLink, especially in mixed lots.
- Always verify current sold prices yourself before pricing your own inventory. Don't rely on numbers you saw months ago.
What Is LEGO Alien Conquest, and Why Do Collectors Still Ask About It?
LEGO Alien Conquest is a retired theme built around a human resistance fighting off a UFO invasion, released in the early 2010s and produced for a couple of years. Collectors still ask about it because the aliens are visually distinct, the sets were short lived, and nostalgia for that era of LEGO sci fi has grown steadily.
The theme leaned hard into a campy 1950s style flying saucer invasion look, which is part of why it stands out from other space themes. The alien figures used unusual molds and translucent green pieces that weren't reused much elsewhere, which is exactly the kind of thing that keeps a retired theme relevant to collectors years later. When I sort through old bins, Alien Conquest pieces are usually easy to spot for that reason alone.
Are LEGO Alien Conquest Minifigures Actually Worth Anything Today?
Most Alien Conquest minifigures hold modest but real value, generally more than a random City figure but less than a rare Star Wars or CMF figure. The aliens themselves, especially ones with intact weapons and undamaged printing, tend to be the more sought after side of the theme compared with the human resistance fighters.
Heads up: This is not financial or legal advice. We're sharing what we've learned from the LEGO reselling community.
I've seen enough of these change hands to say the range is wide. A common resistance fighter in okay condition might not move for much at all, while a complete alien figure with its full weapon and no cracked plastic can do noticeably better. From what I've tracked, condition and completeness matter more for this theme than for a lot of other retired lines, because the alien pieces are easy to chip or lose. Always check current sold listings before you set a price, since values shift and I'd rather you verify than trust a number that's already stale.
What About Space Police Minifigures? Are They a Separate Market?
Space Police is its own theme with its own collector base, and while it sometimes gets lumped in with Alien Conquest because both are space and alien adjacent, the two don't sell to identical buyers. The most recent wave, generally dated around 2010 to 2013, introduced the robotic looking officers and alien criminals that collectors still ask about today.
In my experience, Space Police figures with unique alien criminal designs tend to outperform the standard human officers, similar to how Alien Conquest's aliens outperform its human resistance side. A seller I know who focuses on retired space themes told me the alien criminals are usually the first things to sell out of a mixed lot, while the plain officers sit longer. That lines up with what I've noticed watching these move through bulk lots myself.
Which Alien Conquest and Space Police Figures Tend to Sell for the Most?
The figures that sell for the most are almost always the ones with unusual molds, full accessories, and clean printing, not the generic human characters. Across both themes, the alien and criminal side figures consistently outperform the human resistance fighters and police officers because they're visually distinct and harder to substitute with a similar figure from another theme.
I'm not going to hand you specific dollar figures or ID numbers here, because prices move and I don't want to hand you a stale number that turns out to be wrong. What I will say is this: completeness is the single biggest lever. A figure missing its blaster, jetpack, or helmet visor typically sells for a fraction of a complete one. If you're trying to identify exactly which variant you're holding and what it typically brings, that's the kind of lookup I built brick'em's minifigure database to handle, since guessing from memory is how people underprice good figures.
How Much Difference Does Condition Actually Make?
Condition makes a bigger difference on these two themes than on a lot of other LEGO minifigures, mainly because of the translucent alien pieces and the printed detail on the police officers. A figure with yellowing plastic, cracked translucent parts, or worn printing will typically sell for noticeably less than the same figure in sharp condition.
| Factor | Why It Matters | Impact on Price |
|---|---|---|
| Completeness (weapon, helmet, accessories) | Missing pieces are hard to source individually | High |
| Printing condition | Faded or worn prints are visually obvious | High |
| Plastic clarity (alien pieces) | Translucent green parts can yellow or crack over time | Medium to High |
| Original packaging | Adds collector appeal but isn't required for value | Medium |
| Which specific variant | Alien and criminal designs generally outperform human characters | High |
I use a checklist like this every time I'm sorting a bin that might have Alien Conquest or Space Police mixed in, because it's easy to grab a figure, assume it's a "cheap" one, and toss it in a bulk pile when it actually had a missing part worth tracking down first.
Where Should You Actually Sell These Figures?
For most sellers, BrickLink is the best place to check pricing and sell individual Alien Conquest or Space Police figures, while Whatnot and eBay tend to move mixed lots or bundles faster. BrickLink functions as the pricing backbone for the whole LEGO resale world, which is exactly why I lean on BrickLink integrated data before pricing anything myself.
In my view, if you've only got one or two figures, BrickLink is worth the patience since buyers there are specifically hunting for individual pieces and variants. If you've got a bigger lot with a mix of aliens, officers, and other retired figures, Whatnot or eBay usually clears inventory faster, especially if you bundle a few together. eBay's promoted listings can push the effective take rate close to 25% of a sale once you add them in, so factor that into what you're actually netting before you decide where to list.
Is This a Good Niche for a Beginner Reseller?
Alien Conquest and Space Police are a reasonable niche for a beginner, but not the easiest one to start with compared to something like Star Wars or Ninjago. Demand exists and is steady, but it's narrower than the big licensed themes, so figures can sit longer before finding the right buyer.
I recommend beginners treat these two themes as a supplement to a broader minifigure strategy rather than a starting point on their own. When I sell a mixed lot that includes a few alien or space cop figures, I don't expect them to be the fastest movers, but they usually add real value to the total once someone who specifically collects that theme finds the listing. Patience matters more here than with mainstream themes.
How Do You Avoid Overpaying When Buying Bulk Lots With These Figures Mixed In?
The best way to avoid overpaying is to estimate the value of a bulk lot based on its weakest, most common figures, not its best case scenario, and treat any Alien Conquest or Space Police figures as a bonus once you've identified them. Sellers who price lots assuming every figure is a top variant usually end up disappointed.
I learned this the hard way early on, assuming a bin full of "space stuff" was worth more than it turned out to be once I actually sorted and identified each piece. Now I scan and identify everything before I make an offer on a lot, rather than eyeballing it. If you want to run the math on a specific lot before you buy, brick'em's haul calculator and collection value calculator are built for exactly that, and if you're weighing whether a lot is worth buying as a longer term hold, the investment calculator can help frame that decision too.
Frequently Asked Questions
Are LEGO Alien Conquest minifigures rare?
Some are rarer than others, but the theme as a whole isn't considered ultra rare compared to short run promotional figures. The alien designs with unique molds tend to be harder to find complete and undamaged than the human resistance fighters, which is what drives most of the price difference within the theme itself.
What years was LEGO Alien Conquest released?
LEGO Alien Conquest ran from roughly 2011 to 2012 before being retired. That short production window is part of why collectors still track it. Since it wasn't reissued afterward, the supply of these figures is fixed, which is generally a long term positive for retired themes once nostalgia demand builds.
Is Space Police worth more than Alien Conquest?
Neither theme consistently beats the other. Space Police has run across multiple waves over the years, which gives it a longer collector history, while Alien Conquest's shorter run and distinctive alien molds keep it relevant too. In my experience, specific figure demand matters more than which theme it came from.
Where can I check current prices before I sell?
BrickLink is the standard reference most serious LEGO resellers check first, since it reflects real completed and active listings for individual figures. I also recommend checking eBay's sold listings filter and cross referencing before you price anything, since prices on any single platform can drift from the broader market.
Should I buy a bulk lot just because it has alien or space cop figures in it?
Not on that basis alone. Price the lot based on its overall condition and the most common figures inside it, then treat any Alien Conquest or Space Police pieces as upside if they're complete and in good shape. Overpaying because a listing photo shows one interesting alien figure is a common beginner mistake.
