Is that dusty box of LEGO bricks in your attic worth a fortune?

The world of vintage LEGO has seen a meteoric rise in value over the past few decades, turning childhood playthings into coveted collectables.

There may even be some loft spaces in Southampton with LEGO sets sitting in them.

Recent research by Madbricks looks at the most expensive vintage LEGO sets on eBay and reveals that nostalgic treasures from your childhood are now highly sought-after collectables.

Limited production runs and discontinued sets make certain LEGO pieces highly sought after and well-preserved sets, especially in their original packaging, command premium prices.

The emotional connection many adults have with LEGO from their childhood drives demand.

Certain sets, like the iconic Castle or Space themes, are more valuable than others and specific pieces, such as rare colours or molds, can also increase value.

Complete sets with original instructions and boxes are worth more and pieces should be clean and undamaged.

Original packaging, especially sealed boxes, is a game-changer for value and missing pieces can significantly reduce a set's worth.

If you have any of these LEGO sets, you could be sitting on a goldmine:

A rare pre-owned Star Wars LEGO collection sold for almost £30k and a brand new LEGO Star Wars: Cloud City sold for £13.5k.

A sealed LEGO Castle Knights Kingdom was purchased at auction for £12k while a used LEGO Monorail Airport Shuttle fetched £10.9k.
