Greg is a highly skilled professional who has earned the respect of dealers and collectors alike over his decades in the hobby.

The award recognizes numismatists for their devotion to numismatics and for their significant additions to the body of PNG membership. Greg has been deeply involved with the hobby since he was a teenager. He started his own business in 1990, and that business has grown into a multi-billion dollar organization with affiliates headquartered on three continents.

“Greg is one of the savviest people I have ever had the pleasure to know, if not the savviest,” commented Stack’s Bowers Galleries President Brian Kendrella. “I am so thankful to have worked with and learned from him for the past 15+ years. There is no one more deserving of this great recognition than Greg.”

Greg brings to the hobby an extensive knowledge of the precious metals industry and in-depth experience in rare coin grading, trading and collecting. These attributes have kept him in the forefront of the hobby, including being named as one of Coin World’s Most Influential People for four years (since its inception) and being honored in CoinAge’s Book of Lists as one of the World’s Greatest Coin Graders. In 2020, Greg was inducted into the Professional Coin Grading Society’s Coin Dealer Hall of Fame and in 2011 he received the American Numismatic Association Harry J. Forman Dealer of the Year Award, presented to an ANA-member dealer who shows uncommon dedication to strengthening the hobby.

Greg is a highly skilled professional who has earned the respect of dealers and collectors alike over his decades in the hobby. His impact on the business has been significant, and he continues to spearhead innovative programs to enhance collecting in today’s market. He is a member of the Professional Numismatists Guild (PNG), a life member of the American Numismatic Association (ANA), and a member of the Industry Council for Tangible Assets (ICTA).
