LONDON: An exclusive trading card depicting US basketball superstar LeBron James of the Los Angeles Lakers is expected to fetch more than $6 million at an auction this week, according to the auctioneers selling it. The one-of-a-kind card, which was found during a social media event after a 12-month search, features the 18-time NBA All-Star includes patches taken from jerseys James has worn throughout his career. Canadian rapper Drake had bought 10 cases of basketball cards to try and find the elusive collector’s item. “The best comparison that I can use for the modern reader is imagine Willy Wonka and the Chocolate Factory, looking for that golden ticket,” Ken Goldin, executive chairman of auctioneers Goldin, said. “And then imagine there was only one golden ticket instead of five.” An “ultra-rare” rookie card signed by James, a four-time NBA champion, previously broke the record for most expensive basketball card sold last year, fetching $5.2 million. The auction opens on Wednesday and closes on June 25. The sale comes after James became the first active player in NBA history with a net worth of $1 billion, according to Forbes magazine.
