Step up to the plate with the Pawn Stars as they check out a Babe Ruth baseball card from when the Bambino was a pitcher with the Boston Red Sox. Will they swing for the fences for this rare card, or will the seller throw them a curveball? Then, Corey eyes an officer's artillery sword from the War of 1812. Will he keep his edge or will the deal be cut short? And later, Corey and Chumlee are offered a keyboard used by the band Three Dog Night. Can this piece of classic rock memorabilia have the guys singing "Joy to the World?"
