'Hardcore Pawn' guys teach art of selling

The guys behind the TruTV hit "Hardcore Pawn" stopped by Windy City Live.

Les and his son, Seth Gold, helped Ryan and Val master the art of selling.

Les built American Jewelry and Loan from the ground up.

It's the largest pawn shop in Detroit.

He's an old school, hard-nosed pawnbroker at heart with a passion for collecting unusual items and a nose for deals - and people.

Les's only son, Seth has worked full-time at American Jewelry and Loan since graduating from college. Seth prides himself on bringing a contemporary corporate structure to his family business and revolutionizing their marketing efforts, and he never hesitates to point out to his father where there is room for improvement.
