A teenager who started selling unwanted toys online has built a Lego empire worth hundreds of thousands of pounds after spotting a gap in the collector market. Jamie Bell began selling his old toys on eBay at just 13, but quickly realised Lego pieces were far more valuable than he expected. Now 18, his business JTB Collectables buys large quantities of Lego bricks and minifigures before selling them to collectors and resellers around the world. Jamie’s growing operation generated £300,000 in revenue last year, although he was left with around £50,000 profit after costs. At 14, he bought a bundle of Lego and sold the pieces individually for twice what he paid.
