Every holiday season, thousands of people who don’t normally shop for LEGO® suddenly do. Some are simply looking to make a child in their life happy. Others go out hunting for a nostalgic or memorable gift for that special someone — searching high and low for that retired set they’ve dreamed of for years.
The tricky part is that when demand spikes like it does during the holiday season, so do the two biggest risks you need to watch out for:
1. Counterfeit LEGO® sets (100% fake).
2. Scammers selling real LEGO that has been opened, resealed, or tampered with.
Fake LEGO is one problem (think Lepin and similar brands). Tampered LEGO sets are a completely different — and unfortunately increasingly common — problem.
At Baronneau, we’ve handled thousands of sets and seen every trick in the book. Some fakes are blatantly obvious. Others look very convincing. And some scams come in the form of real LEGO sets that have been resealed after:
-
stealing minifigures
-
removing exclusive parts
-
replacing real LEGO bags with knockoff bricks
-
swapping damaged boxes for nicer ones
-
reprinting seals or using heat-guns to fake them
I’ve written this guide for holiday shoppers who are new to retired LEGO® sets — though even experienced AFOLs might pick up a few things. My hope is that by the end, you’ll feel confident buying retired or high-value LEGO® sets safely — and you’ll know exactly how to avoid fakes or tampered boxes. Here’s what to watch for…
1. The Two Biggest Threats This Holiday Season
When buying LEGO on Facebook Marketplace, Kijiji, eBay or anywhere outside an established store, you’re exposed to two risks:
A. Fake LEGO (counterfeit, imitation, knockoff)
These sets are not LEGO. They mimic LEGO themes (Star Wars, Marvel, Icons, Technic, etc.), but the quality is terrible and the parts are unsafe.
B. Real LEGO that has been tampered with
This is more dangerous because people trust the LEGO brand. Scammers take a real LEGO box and:
-
open it with steam or a heat gun
-
remove minifigs (often the most valuable part)
-
steal specific rare pieces
-
replace LEGO bags with knockoff bags
-
reseal the box to make it look unt
-
ouched
This type of scam is extremely common during the holidays — especially for retired sets or anything packed with desirable minifigures.
2. How to Spot Fake LEGO® Sets (Counterfeits)
Counterfeits fail on quality, branding, and consistency. These signs apply whether you’re buying locally or online.
A. Box quality is the #1 clue
Fake LEGO boxes often have:
-
blurry images
-
wrong colours
-
very thin cardboard
-
weird gloss or matte finish
-
slightly distorted layouts
-
printing that looks “off” when zoomed in
Real LEGO boxes are printed with extremely high resolution and consistent colours. Anything that looks even slightly cheap or pixelated should raise concern.
B. Incorrect or sloppy LEGO logos
Counterfeits often show:
-
stretched or squished logos
-
dull red instead of LEGO’s bright red
-
uneven yellow outline
-
low-resolution print
C. Missing licensor logos
Licensed LEGO themes always include official branding:
-
Star Wars → Lucasfilm / Disney
-
Marvel → Marvel / Disney
-
Harry Potter → Wizarding World
-
Disney → Disney
-
DC → DC Comics
If a set claims to be Star Wars but has no Lucasfilm or Disney branding, it’s fake.
D. Wrong or nonexistent set numbers
Counterfeits sometimes:
-
invent fake set numbers
-
reuse numbers from unrelated sets
-
use wrong fonts or spacing
-
place the number in the wrong area of the box
If the number doesn’t match LEGO’s catalog, it’s fake.
E. Minifigure quality issues
Fake minifigs reveal themselves instantly:
-
loose limbs
-
poor printing
-
misaligned graphics
-
odd colours
-
soft or gummy plastic
-
missing “LEGO” embossing inside parts
F. Bricks that don’t feel right
Counterfeit bricks often:
-
have weak clutch power
-
feel softer or lighter
-
show rough edges or mold lines
-
have uneven colours
-
emit chemical smells
-
lack identifying marks (with a few exceptions)
Real LEGO bricks have a consistent feel and precise manufacturing.
3. How to Spot Tampered or Resealed LEGO® Sets (Scams)
This is where real LEGO is used dishonestly. The box is genuine, but the contents inside aren’t what they should be. This is by far the most common scam in Canada.
Scammers typically target retired, expensive, or minifigure-heavy sets — and sometimes even current sets.
A. Minifigure theft (the #1 scam today)
Minifigures are often the most valuable part of a set. Scammers open the box, remove the minifig-bags, and reseal the box. The outside looks untouched, but the most valuable content is gone.
Signs this has happened:
-
box looks re-taped or heat-sealed
-
tape edges are uneven or peeling
-
slight discoloration around seals
-
bag count seems low or the seller avoids showing numbered bags
-
seller refuses to show sealed bags
-
seller claims “opened to check” — a major red flag
B. Swapped or replaced bags
Real LEGO bags have printed numbers and batch codes. Scammers may:
-
remove bags
-
insert knockoff bags
-
mix bags from other sets
-
replace numbered bags with unnumbered ones
If unsure, search YouTube for an unboxing of that exact set — you'll see every bag and element that should be inside.
C. Reprinted or fake seals
Real LEGO seals:
-
are clean
-
have even glue
-
do not peel easily
Scammers may use packing tape, heat guns, double-sided tape, or glue sticks.
Watch for: foggy plastic, melted spots, lint under tape, overlapping tape, distorted edges.
D. Missing exclusive elements
Some sets include chrome pieces, printed tiles, unique colours, or specialty molds. Scammers may remove only the rare parts because they resell well.
E. Weight inconsistencies
If the box feels too light, a bag or minifigure may be missing.
F. “The box was damaged so I re-taped it”
Real sellers do not re-seal LEGO boxes. Ever.
4. Red Flags That Mean “Don’t Buy This Set”
❌ Seller avoids close-up photos
❌ Photos are stolen or taken from LEGO®
❌ Price is unrealistically low
❌ “New, but I checked the contents”
❌ Mismatched or messy tape on seals
❌ Seller can’t explain where the set came from
❌ Location switching
❌ Seller pushes for a nighttime meetup or quick sale
5. Where These Problems Happen Most Often
High-risk platforms:
-
Facebook Marketplace
-
Kijiji
-
Craigslist
-
Flea markets
-
Online classifieds
-
AliExpress
-
Any site offering “LEGO-style” or “compatible” bricks
Medium-risk:
-
Pawn shops
-
Unknown sellers without any track record
-
Random online toy websites with incredible prices
Safe places:
-
LEGO Store
-
LEGO.com
-
Established toy retailers
-
Trusted collector shops (like Baronneau)
-
Sellers with receipts, history, and proof of authenticity
Even in safe places, you still need to stay alert. Authorized retailers have been repeatedly hit by the “buy, steal the minifigs, reseal, and return it” scam — and rushed clerks don’t always catch the signs.
6. How to Protect Yourself This Holiday Season
✔ Compare prices
✔ Ask for photos of the seals
✔ Ask for photos of the numbered bags
✔ Avoid “opened to check”
✔ Review the seller’s history
✔ Buy retired sets only from trusted retailers
✔ Ask an expert if unsure — Baronneau is always happy to help
