The Pawn Stars hope to remain civil when a man brings Robert E. Lee's silver spoon and Ulysses S. Grant's meerschaum pipe. Can Rick scoop up these pieces of American history or will the seller just be blowing smoke? Then, Corey and the Old Man place their bets when a shoe from the legendary Triple Crown racehorse Secretariat gallops in. Will this horseshoe prove to be their lucky charm or will the race to the finish line come up short? And later, a seller hopes he has found hidden treasure when he strolls in with a vintage metal detector. Do the guys detect a deal or is the seller's excitement a false alarm?
