A lucky collector from the UK pulled a one-of-a-kind Luke Littler trading card, but faced challenges when trying to sell it. The card, part of an extremely limited set, was highly sought after and eventually sold for $17,905, making it the most expensive darts card ever sold. However, the highest bidder failed to pay, and the card was eventually sold to a stock trader for over $10,000. The collector plans to celebrate his windfall by flying to Scotland to meet a friend he made through Pokemon.
