"Pawn Stars" Rick Harrison and Chumlee have a chance to snap up a one-of-a-kind piece of memorabilia ... courtesy of an NFL player holding on to a Pokémon card worth 6 figures!!!
Rick and Chum met up with Raiders' linebacker Blake Martinez Thursday night during a meet and greet at Gold & Silver Pawn Shop in Las Vegas.
Blake brought his very rare card -- a Pokémon Illustrator -- and the guys got a close look. It is said to be one of the rarest cards in Pokémon history, as only 4 were ever made.
