Overview: It's a blast from the past for the Pawn Stars when they check out a huge collection of mini bikes from the 1970's. Will the guys saddle up and buy the micro machines, or will they hold out for the full-sized counterparts? Then, an early 1900s baseball bat swings into the shop. Will Corey and Chumlee hit a hum-dinger of a deal, or will they let it walk? And later, Rick is presented with a piece of mail flown by Charles Lindbergh on the Spirit of St. Louis. Will he soar to new heights for this historic piece of airmail or will the negotiations stall out and take a nosedive?
