Dr. Gene Gress, Numismatist - Dr. Gress has been an avid coin collector since the age of 6. His collecting interests developed from time spent with his uncle. Gene has a passion for the Morgan dollar series and has discovered scores of new Vam varieties which have subsequently been published. At one time he had one of the finest and most extensive VAM collections in the country. Although Gene's career path took him in a direction other than numismatics, he is a dentist by trade, the skills he acquired on the job were applicable to numismatics as well. He found the skill of paying attention to the smallest detail became especially helpful when looking for minute differences between die varieties. In the past, quite often, Gene was seen helping coin dealers on weekends at local and national shows. He found a way to squeeze in the fun of the rare coin business with his practice of dentistry. Numismatics has always been one of Gene great passions. His enthusiasm over seeing a neat colonial or an important Seated half dollar or a tiny California Fractional, is contagious. He loves them all! Additionally, he is a skilled marksman, sports enthusiast and has been known to own and drive a fast car or two! Gene has also served our great country as an officer in the United States Air Force. We are pleased to welcome Gene to our staff. His extensive knowledge of die varieties, coupled with a keen eye for grading and great work ethic, make him a terrific asset to our staff
