At just 18 years old, South London reseller Jamie Bell has already generated around £300,000 — more than $400,000 — in annual sales from selling LEGO on eBay.
Bell, who runs JTB Collectables, got into reselling LEGO when he was just 13 years old. What started with selling unwanted toys quickly developed into a serious resale business.
Within only a few years, the amount of money going through his eBay account had grown so much that he needed professional help.
“I had to get an accountant at 16, but I probably needed one at 15,” Bell told Kennedy News and Media.
A big part of Bell's business is buying LEGO in bulk and identifying stock that can be resold to collectors and other resellers. By the age of 15, he had realised there was particularly strong demand for large bundles.
“I realised people would buy them to sell each one individually and I could be their supplier,” he said.
Bell also says one of the things he enjoys most about selling on eBay is the auction itself — particularly watching buyers compete in the final moments.
“It’s exciting watching the auctions because sometimes someone will pop in right at the end and increase the price by a few thousand,” he said.
One auction demonstrates just how far the business has come.
In May 2026, Bell listed approximately 95kg of LEGO Star Wars minifigures on eBay. The auction started at just £1, attracted 65 bids and eventually sold for an astonishing £22,428.
But Bell's story also highlights something every reseller should understand: sales and profit are two very different numbers.
Although JTB Collectables generated around £300,000 in revenue during the last tax year, Bell was left with approximately £50,000 profit after costs. US reports converted those figures to more than $400,000 in sales and nearly $68,000 in profit.
Much of the money generated by the business has to go straight back into sourcing LEGO that Bell believes he can resell successfully.
Perhaps most interestingly, despite building a business that many people twice his age would be proud of, Bell still describes it as a side hustle.
He plans to study history and does not currently see LEGO reselling as his only future career.
“I could make it my full-time job but for career stability I'd like to have a profession as well,” he said.
Bell also says he is saving most of the money he makes towards buying his first home.
For anyone getting into reselling, his story is a remarkable example of just how far a niche, some knowledge and an eye for stock can go.
He started selling LEGO at 13. Five years later, his business was doing around £300,000 a year in sales.
