Danielle has a sketchy lead. She's found an incredible collection but the bad news is it's owned by a reluctant seller. However, once inside the man's jam-packed barn, Mike finds two very rare bikes. One is a turn-of-the-century wood rim bicycle and the other, an even rarer 1880s high-wheeler. Can he keep a poker face and strike a deal? Also, Mike and Frank return to pick from Leland, the WWII vet in the Big Bear episode where they bought a sword and saddle. Leland and his daughter invited them back. Mike and Frank bring him a special gift they picked up earlier...and find more treasures at his place.

Concerned about slow sales and high expenses, Danielle tells the guys they need to step up their game and make some serious money. Mike and Frank feel the pressure. They uncover lots of great stuff in Tony's sprawling Illinois collection, but not the big-ticket item they're looking for. It doesn't get much better in a small town they come across. There, they spot some great vintage garage signs, and although they're not for sale, Ken has room after room of unusual items, including an early bicycle and rare Victorian-era erotica. But their luck really changes when Danielle calls with a lead about Hobo Jack. When the guys walk into his hidden, heavily wooded overgrown property, they are surprised by his incredible collection. But will they find the mother lode they've been looking for?
