Hoping to score big on the East Coast, Mike and Frank make stops in Virginia, DC, and Maryland, and are delirious when they find themselves waist-deep in a treasure-packed machine shop. Harry's property is wired for maximum security and once the guys gain access to his amazing vault, Mike makes a high-stakes gamble. Driving off the beaten path, the guys run across a quirky artist with a wacky sense of humor and a sprawling Virginia property packed with funky collectibles. After wading through building after building, Mike pounces on a one-of-a-kind feline with an impressive pedigree. Featuring the mother lode of "petroliana," Mike and Frank scour a defunct Maryland oil company where everything is for sale. Tim is hoping to make some money to revive a vintage local beer and the guys are determined to help him clear out some of his unique mint-condition inventory.

Danielle turns up a good lead she's been working on for months. When Mike tells Frank let's pack up for a trip to South Dakota, Frank says he can't. He's secretly going to his 30th annual trip to the legendary Sturgis motorcycle rally, but says he'll cover the shop. So Mike takes Danielle, first to Dollar Dick's, a tough-minded auction aficionado whose yard is covered in rusty gold. Next, they happen upon what looks like a tourist trap, but the 1880s ghost town pays off with a speed pick in a pair of treasure-filled silos that turns up some unusual items. Finally, they get to Dave's amazing automotive collection where Mike spies a sexy belly tank cycle car with classic Hollywood history.
