Ring around a Rockne

The Pawn Stars are blown away when a signet ring that belonged to mob boss Lucky Luciano comes out of hiding. Can the guys make the seller an offer he can't refuse, or will this deal go to sleep with the fishes? Then, Rick is in the red zone when a letter signed by legendary football coach Knute Rockne steps up to the line of scrimmage. Will Rick win one for The Gipper, or will he fumble the negotiation? And later, Chumlee is presented with a collection of antique Cracker Jack toys. Will he go three strikes and out on these classic collectibles or will he win one for the home team?
