Items appraised include an 1874 Sharps buffalo rifle; a framed 1900 aphorism signed by Mark Twain; a trinitite souvenir from the Manhattan Project that was purchased at auction; and a collection of five late 1800s pickle casters brought in by a chef who has been collecting them since the 1970s. Also, Chumlee begins to follow the Old Man around the shop in the hope of hearing some notable aphorisms that he can frame and sell for a profit.
