Don Presley Auction is the home base for History Channel's all-new show, "Real Deal," airing Sunday evenings at 9PM/8PM Central

In the unpredictable market for collectibles, everyone wants to turn a profit. Real Deal focuses on the high-pressure, drama-filled interactions between buyers and sellers as they haggle over pieces of history. During these tense negotiations, dealers must capitalize on their extensive knowledge of both antiques and human nature to make the trade. But at the end of the day, it’s the sellers who really have the upper hand. They can walk away from the table at any time and head straight to the auction block, where big money might just be waiting. Then again, there’s always the risk of going home with less than the dealer offered—or, worse, empty-handed.

Whether it’s a collection of footballs signed by NFL legends or Harry Houdini’s autograph, a German stormtrooper dagger from World War II or a 19th-century spittoon, the relics featured on Real Deal convey fascinating information about how people lived in bygone eras. But a treasure that’s rich with history doesn’t necessarily fill its owner’s pockets. Sometimes, however, mementos from the past can yield giant cash presents when sellers take a gamble at the auction house.
