In this 5:24 video clip filmed in cooperation with PSA/DNA Authentication Services, John Reznikoff talks about Mark Hoffman aka “The Mormon Murderer,” a Utah-based autograph dealer turned forger, counterfeiter, bombmaker, and convicted murderer now serving a life sentence. Reznikoff provides us with insights into Hoffman’s forgery methods, so that today’s collectors can identify red flags such as “alligator ink.” Reznikoff still sees examples of Mark Hoffman forgeries in the market today.
