The world's rarest and most valuable LeBron James basketball trading card according to some collectors is currently up for auction. And with fewer than two weeks remaining, bids are expected to reach $200,000.

Sports memorabilia expert Ken Goldin says a collector pulled the one-of-a-kind card out of a pack in 2003 and held on to it for more than 10 years.

"It's sorta like finding Willy Wonka's golden ticket," Goldin said. "It really is the Holy Grail of modern trading cards."
