Specialties: Colonial American Coinage, US Coins
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.

Specialties: Colonial American Coinage, US Coins
View Biography
An award-winning professional numismatist, Mark Borckardt has served the hobby full-time since 1980, and is currently a senior numismatist and cataloger with Heritage Auctions, a position he has held since June 2004. His interest in numismatics dates to the mid-1960s, and his experience in the business began part-time attending coin shows to buy and sell material about 1970.
Borckardt began cataloging rare coins for auctions in 1989, and since that time he has handled 80 of the 100 top United States coins according to the itemization contained in 100 Greatest U.S. Coins by Jeff Garrett and Ron Guth. He is a life member of the American Numismatic Association, Early American Coppers, and the Numismatic Literary Guild, and a member of several other numismatic organizations including the American Numismatic Society, the Chicago Coin Club, the Central States Numismatic Society, the Civil War Token Society, and Florida United Numismatists. Borckardt was nominated and elected to membership in the Rittenhouse Society in 1994.
With Heritage Auctions, Borckardt has cataloged 28 of the firm’s million-dollar coins. His numismatic experience includes important discoveries such as a new early half dollar variety, 1806 O-130 and rediscovery of the missing George O. Walton specimen of the 1913 Liberty nickel. Borckardt is co-author of Million Dollar Nickels, telling the story of that important numismatic event. He is the editor of Walter Breen’s Encyclopedia of Early United States Cent, 1793-1814, earning the EAC Literary Award in 2001 and the NLG Book of the Year award that same year. He has also contributed substantially to many other numismatic reference works. In addition, Borckardt has penned many articles for The Numismatist, Penny-Wise, and other numismatic publications.
Borckardt has contributed substantially to countless numismatic auction catalogs, and served as the sole cataloger for several important catalogs. He has experience with many of the most important collections sold at auction including the Eliasberg Collection, the Harry Bass Collection, multiple collections of Dr. Steven Duckor, the Eugene H. Gardner Collection, the Eric P. Newman Collection, the Donald G. Partrick Collection, and others. The Newman and Partrick Collections included significant offerings of American colonial-era coins.
Awards include the Early American Coppers’ Herbert Silberman
Award in 2021, the ANA Numismatist of the Year in 2020, an ANA Presidential
Award in 2018, the Numismatic Literary Guild’s Clemy Award in 2016, and several

Marc Emory
Director of European Operations

Specialties: Ancient Coins, US Coins, World Coins
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.
