Plot: The Pawn Stars get a call about a 1979 KISS pinball machine - can it still "Rock 'n Roll All Nite", or will it steal Corey's quarter and KISS the deal goodbye? Then Rick is stumped when a woman brings in a 1914 Star-note $20 bill. Will everyone walk away with new money, or will it turn out to be chump change? And when an old easy rider brings in his classic 1982 Harley Davidson Shovel-head, Chumlee decides to buy it for himself - but can he raise the cash before the Old Man sells it off
