I have 28 years of experience and specialize in the field of numismatics with specific knowledge in the areas of US and foreign coins and currency. I have published on such topics as valuation, Texas Colonial Jola and Aramco gold. I have testified on rare coin valuations. I have been a numismatist for 46 years and a certified ASA appraiser for the past 27 years. I appraise and liquidate coins and collections for both the public and institutions. I am a member of a number of a number of numismatic-affiated organizations and guest speak regularly on many coin related topics.
