Markham Numismatics  Coin Appraiser       Date of Death Appraisals 

True experience and knowledge of the coin business is gathered slowly from seeing millions of coins, understanding how each mint and each year has different characteristics features and seeing counterfeits first hand. It is not something you learn overnight. It takes years of experience in the trade. I became an expert by working in the coin business since he was 16. At 19, I worked as a coin buyer for David Hall rare coins and later worked as a coin grader for Professional Coin Grading Service (PCGS) grading coins at the age of 21. Being an expert is not just a word but the knowledge gathered in a lifetime.
