Over the last several years, I learned a decent amount about coin collecting and based on that, felt that Howards assessments and appraisal were fair. He continually checked in with me on my level of understanding and agreement. I would also add that his accommodations definitely allow customers bringing in their own collections to feel secure and confident with dedicated attention. With no hesitation, I recommend!— Karen Hope, Jan 2026
Howard was very professional and honest with us. He took the time to look at all my coins, and there was a lot. We made out way better than we thought we would. I recommend his services to anyone that has questions about coins. Thank you for all your help Howard.— Chris Beckwith, Jan 2026
My family inherited a Morgan Silver dollar collection that sat I the garage for more than 10 years. Not having any idea how to sell the collection, I reached out to Markham Numismatic. Howard met me and within 30 minutes, offered a fair price for the entire collection. It was a great experience and Howard took the time to explained how he got to the offer. If I ever find myself in need of a professional numismatist, I'm going straight to Howard Markham.— Rob Gaylor, Feb 2026
Howard delivered an outstanding client experience at every stage—from our first phone conversation and initial quote through final transaction. His expertise, honed through his previous role as a PCGS coin grader, was complemented by his professional demeanor and genuine willingness to educate. He provided numerous insights that proved invaluable to someone less familiar with the industry. I would highly recommend Howard to anyone seeking knowledgeable and professional service in this field!— Alayra Family, Jan 2026
Howard Markham was highly recommended to me and my family by our attorney, as we inherited a large amount of gold and silver coins, jewelry and generations of family sterling silverware to sell. Howard was wonderful. My brother and I liked him immediately. He is highly knowledgeable and trustworthy. He is easy going and made the process enjoyable. He has quite an impressive resume as he will share this with you. A great guy who began learning the coin business with his Dad when he was 12. Highly recommend!— Gay Reeves, Jan 2026
