Roxana Uskali, the Director of Numismatics for Heritage
Auctions’ Chicago office, started collecting coins like many of you — as a
youngster who frequented a local coin and stamp shop in her neighborhood. She
went on to graduate cum laude from Loyola University Chicago, receiving degrees
in world history, theology, and piano performance before pairing her diverse
academic background and her love of traveling into a career in professional
numismatics. Roxana spent nine years working as the principal world coin
numismatist for the prestigious Chicago firm Harlan J. Berk, Ltd., and more
recently her own company, KRCoins. Over the last several years, she has helped
catalog Heritage’s world coin auctions while also frequently attending major
coin shows around the U.S. and abroad. In addition to being a member of the
ANA, the IBNS, and the CSNS, Roxana also produces coin-related videos called Coincasts.

Marc Emory was born in northern Virginia, where he grew up as the son of a Washington correspondent of a newspaper in Upstate New York. A child of the Washington political scene, he was visiting the White House at age 13, and Capitol Hill many times before that. Like so many children of Washington, he attended the Sidwell Friends School. He than was accepted for the Schoolyear Abroad program in Spain, then sponsored by the two Phillips Academies (Exeter, NH and Andover, MA). After the year in Barcelona, he went on to graduate from Andover (1970), and four years later graduated cum laude from the University of Pennsylvania (1974), with a degree in Spanish. He always had an interest in languages, and while at Penn got his introduction to German and Swedish, in addition to continuing his studies in Spanish and Russian from high school. In addition to those four languages plus Catalan, a byproduct of his year in Barcelona, he has since learned French, Italian and Dutch.
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.

Nicholas Mathioudakis has been collecting coins since the age of thirteen. Having lived in Saudi Arabia, he would spend a lot of time roaming the souks in search of hidden treasures where he also bought his first ancient Greek coin. His drive and passion for numismatics led him to take up a full time position at Morton and Eden (formerly associated with Sotheby’s) where he catalogued ancient coins and paper money. Mathioudakis’ areas of expertise include ancient coins, paper money, particularly of the Middle East, European medieval, Islamic and Modern coins.
A coin collector and enthusiast from an early age, Cale received his BA in Anthropology, History, and German from the University of South Dakota in 2017. As an undergrad, Cale further developed his knowledge and interest in medieval European and Islamic coins and history, and began to apply the research methods he was learning at college to his personal collection. He also became deeply interested in studying the social functions of coins throughout history, a topic he continues to explore in his free time. Cale joined the Heritage Team full-time in January 2018 as a member of the World and Ancient Coins Department after interning during the end of 2017, and currently enjoys bringing his expertise and curiosity to the department's weekly internet and signature auctions. He is also working to refine his knowledge of Islamic coinage, an area of particular personal interest, to lead that division of the World and Ancient Coins department. His personal collecting interests include principally medieval hammered coinage from Europe and the Islamic world, though his collecting preferences remain quite varied and he is always interested to learn about new areas of coinage.
