Jim Stoutjesdyk
Vice President of Numismatics
1-800-USCOINS (872-6467) x1310
View Biography
Since coming to Heritage in 1993, Jim has assumed a wide variety of responsibilities. He initially was hired as the Gallery Manager for Heritage's retail showroom. For several years he helped to develop Heritage's retail clientele and placed millions of dollars worth of rare coins with collectors. Jim's talent for writing and passion for numismatics led him to become the editor of Heritage's Insider magazine. From 1998 to early 2000 this bi-monthly publication brought collectors the latest offerings from Heritage's inventory and featured a wide variety of informative articles. With the rapid development of Heritage's web site and instant access to our inventory, the Insider magazine was phased out. Jim's interest turned to wholesale trading and he quickly became a familiar face at coin shows across the nation. As Vice President, Jim's duties include buying and selling millions of dollars worth of rare coins each month, pricing all of the new coins available for sale each day, and overseeing the daily operations of the rare coin department. In 2019 the American Numismatic Association awarded Jim the very prestigious Doctor of Numismatics honorary degree.

Marc Emory
Director of European Operations
1-800-USCOINS (872-6467) Page
View Biography
Always interested in collectibles, he was impressed from early childhood by the Smithsonian collections of both coins and minerals, which were within walking distance of his father's office at the National Press Building at 14th and F streets in Washington, D.C. He maintains an extensive collection of minerals at his German home, near the Rheinland city of Dusseldorf, which he shares with his wife of 25 years. His wife, Elisabeth, is a German native, and they speak German at home. Their two bilingual daughters currently attend universities in the United States, after secondary school education in Germany. Marc also has a collection of U.S. coins and an assortment of guitars hand-crafted by legendary luthier Bozo Podunavac. A musician by hobby, he has made recordings and done solo concert tours in his spare time, a commodity which he finds in all too short supply of late.
After graduating from the University of Pennsylvania, Marc joined one of the two firms that later merged in late 1982 to form Heritage. He is has been with the company without interruption since joining in August, 1975. He founded and oversees the operations of the Heritage Overseas offices, which are now in France (since 1979), Germany (since 1979), Switzerland (since 1984), and the Netherlands (since 1990). The Heritage offices in France, Switzerland and the Netherlands are all run by natives of those countries, coordinating in their own languages through Marc at the German office with the Heritage world headquarters in Dallas. The European offices, under Marc's supervision, in turn offer Heritage services to collectors, consignors and estate executors in their own countries and in their own languages, as well as to banks and Central Banks around Europe and the world.
