Remember those Lego sets you loved and played with? It turns out they could be worth a pretty penny now.

According to recent research by Madbricks, vintage LEGO sets from your childhood are fetching high prices on eBay and are now considered valuable collectables.

These sets, once central to your playtime adventures, are now highly sought-after collectables around the globe. Whether they're limited editions, tied to popular franchises or simply rare finds in pristine condition, their value has skyrocketed.

Ant Robinson, a seasoned Lego expert from Madbricks, said: “The market for vintage Lego sets has exploded, turning these childhood toys into serious investments.”

Many buyers are adults eager to recapture their childhood memories, willing to pay top dollar for a blast from the past.

Limited edition and themed sets, particularly those from franchises like Star Wars, are in high demand. Sets that are brand new or in excellent condition command the highest prices.

If you own the following 9 sets, you could be sitting on a fortune of almost a quarter of a million pounds:

• STAR WARS LEGO - RARE Collection [Pre-owned] - £29,999.99
• Vintage LEGO Assortment (320 sets) [Pre-owned] - £16,500.00
• LEGO Star Wars: Cloud City (10123) [Brand new] - £13,500.00
• LEGO Castle Knights Kingdom [Brand new] - £12,000.00
• LEGO Star Wars 7263 TIE Fighter - UCS - SEALED [Brand new] - £11,995.00
• LEGO Monorail Airport Shuttle (6399) [Pre-owned] - £10,900.00
• LEGO Star Wars Millennium Falcon (10179) [Brand new] - £10,000.00
• LEGO CITY Airport (6392) SEALED [Brand new] - £9,999.99
• LEGO Technic 8455 Back-Hoe Loader (sealed) [Brand new] - £9,995.00

As you can see, sealed Lego sets, those in pristine condition and those complete with all their pieces are the most valuable to collectors.

Sealed sets are highly prized because their untouched, factory-sealed state guarantees that they are in mint condition, and collectors place significant value on sets that haven’t been exposed to potential wear and tear.

Sealed sets also ensure that all pieces are original and authentic, which is crucial for collectors who want to avoid counterfeit or incomplete sets.

Missing pieces can diminish the value considerably, making complete sets more desirable and valuable to collectors.

What if I’ve played with my Lego set?

Keeping Lego sets sealed and avoiding opening the box or removing any parts is the best way to preserve their value.

But of course, not everybody has the ability to purchase two copies of a set, and for many people, actually building the model in question is the funnest part.

If you do open a set to build it, store it in a cool, dry place away from direct sunlight and extreme temperatures when you are finished with it. A controlled environment helps prevent damage and deterioration.

Try to keep the original box and packaging in excellent condition, as the box is an important part of the set's value.

Ensure that you keep every single piece and any included instructions, as losing parts or instructions can significantly lower the set’s value. Handle the pieces carefully to avoid any damage.

And if possible, take photos of the set and its components in their original condition - this can serve as documentation to help prove the set’s authenticity and completeness in the future.
