The Pawn Stars have a chance to buy an extremely rare 18th century double-barrel coaching gun engraved with a mysterious golden script. Can they discover its true origins and make a deal or will the inscription hide its secrets forever? Then Corey and Chum meet an outspoken Pez collector looking to sell 50 pieces of classic Americana. Will Corey click out some serious cash for these collectibles, or will he get his sugar fix somewhere else? And later, a woman hopes to sell Rick a 1932 "S" Quarter–a rare version of the first Washington silver quarter introduced into U.S. currency. But Rick has questions about its authenticity, will this quarter be worth its weight in silver, or is it destined for a parking meter?
