In this ‘Pawn Star of the week’ contest, HISTORY will post a picture of an item on its Facebook page and fans can make their guesses on the item’s pawn or sale value by commenting on the picture. The correct or closest estimates win prizes such as a Diana mini camera, a retro Coca Cola Cooler and a Pawn Stars stool.

The American reality television series, which is the network’s highest rated show, chronicles the daily activities at the world famous Gold & Silver Pawn Shop located in Las Vegas. Three generations of the Harrison family run the family business, using their sharp eyes and skills to assess the value of items from the commonplace to the truly historic.
