Retired agent Doug Hess served with the FBI for nearly 21 years. He was assigned for a short time to a satellite office out of the Tampa Division, but spent most of his career in the Philadelphia Division. As a licensed pilot, Hess was initially assigned to the surveillance squad, Special Operations Group (SOG). Later, he returned to working his own cases on a squad handling major theft and interstate transportation of stolen property crimes.  In this episode of FBI Retired Case File Review, Hess is interviewed about his investigation of a scheme conducted to defraud 150 coin dealers and collectors, known as numismatists, of $1 million in gold coins. During the investigation, Hess discovered a second scheme involving lead filled bars of silver that potentially could have been damaging to the precious metals industry. For his efforts in these matters, Hess received the Sol Kaplan Award from the Professional Numismatists Guild.
