Seth Chandler
Witter Coin
Chief Numismatist

Seth Chandler is the owner and Chief Numismatist of Witter Coins.  He started collecting coins when he was four by placing Wheat Cents in blue Whitman coin folders given to him by his parents. Things started getting serious when Seth was ten.  Money earned from mowing lawns was used to buy coins at his local coin store, Edgewood Coin Shop.  Seth spent so much time at Edgewood; they offered him a job, working there from the age of 14 to 18.

Seth has been an avid coin collector for over 40 years and his collecting interests includes early United States gold coins and all coinage minted at the three San Francisco Mints.  When not playing with coins, Seth spends time with his three young children and lovely wife, Jen.

Devin Hipp is a lifelong coin collector and numismatist, and he is recognized in the field for his expansive breadth of numismatic knowledge in United States and world coins with emphasis on coin grading and variety attribution.

His interest in numismatics began at age 10, when his curiosity was piqued by groups of world coins brought back from his father's business travels in Europe. During his middle and high school years, Devin authored over a dozen articles on specialized numismatic topics that were published in the American Numismatic Association's weekly emails for young numismatists called YourNewsletter. He also received six scholarships to attend the ANA's Summer Seminar programs, where he completed courses such as Modern Minting Process, Errors and Varieties, Early American Coppers, 19th Century American Numismatics, Advanced Coin Grading, and American Colonial Coins.

Devin graduated from the Georgia Institute of Technology in August 2012 with a bachelor's degree in Business Management and a certificate in Marketing. Shortly after graduation, he pursued his entrepreneurial ambitions and left his numismatist position with a prominent Atlanta area coin dealer to start Devin Hipp Enterprises LLC, a numismatic trading firm specializing in wholesale trading and building high-end certified coin collections for select clients. From the company’s inception in October 2012 through March 2015, Devin became the largest volume submitter in the state of Georgia of coins to third party grading services and was widely regarded for his keen grading ability and eye for purchasing raw coins for certification.

In March 2015, Devin and his family relocated to Virginia Beach, Virginia, where he briefly explored an opportunity with an internet-based retailer as their lead grader. In January 2017, he reestablished Devin Hipp Enterprises LLC in the state of Virginia. Devin grew the business to become a major submitter nationally to the third party grading services and in 2022 joined Stack's Bowers as Vice President. He also is a co-instructor of Intermediate Coin Grading at the American Numismatic Association’s Summer Seminar.

Devin is a life member of the American Numismatic Association, Georgia Numismatic Association, and Florida United Numismatists.

Jim Stoutjesdyk
Heritage Auctions
Vice President of Numismatics

Jim Stoutjesdyk was named Vice President of Heritage Rare Coin Galleries in 2004. A native of Michigan, Jim has been actively involved in numismatics since a young age and the American Numismatic Association named him their Outstanding Young Numismatist of the Year in 1987. After graduating from the University of Michigan he was employed by Superior Galleries in Beverly Hills, California where he eventually became their Director of Collector Sales.

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.

Steve Feltner
Grading Team Leader
Director of Numismatic Education 


In his role as Grading Team Leader & Director of Numismatic Education and Outreach at PCGS, Steve Feltner hopes to inspire collectors young and old. He began collecting at the age of 8 and was immediately hooked on the history and number of amazing designs. At the age of 13 he became heavily involved with the American Numismatic Association and began attending their Summer Seminars. It was the ANA and their programs that were the catalyst to his future career paths. He has been to Summer Seminar nearly 20 years and has been an instructor for their intermediate grading course 8 consecutive years.

At the age of 25, he was asked to test grade at PCGS for an opening in the vintage room and accepted a full-time position. “I was a vintage grader for a bit over 3 years and learned a great deal sitting next to some of the sharpest graders and numismatic minds of our generation,” Feltner recounted. He later moved to Sacramento and helped found a successful coin company which he built over four years. “I could not be more excited about this role with PCGS as I feel it is a perfect fit for my desire to educate, while continuing to learn from those around me. My goal is to be an open and available resource to share the love of this amazing hobby. I believe that the future of numismatics is bright, so long as we all work together to make positive adaptations to an ever-changing market,” said Feltner.
