We are a professional family business and take great pride in the very personal attention we give to our clients’ needs. We are members of the American Numismatic Association (ANA), the America Stamp Sealers of America (ASDA), the American Philatelic Society (APS), and the Professional Stamp Experts (PSE), and we rigorously comply with each organizations' strict code of ethics.Whether or not you're a stamp collector, we welcome you to be among the thousands of people from around the world who come to our website when they have stamp collections for sale. Dr. Robert Friedman enjoys a reputation throughout the philatelic hobby as one of the major buyers of any valuable stamp collection. From jumbo collections that would, quite literally, fill a moving truck to a small envelope filled with high quality stamps, Dr. Robert Friedman is very interested in any valuable stamps you have for sale. Many people who have sold to us have never had any experience with stamp collections. In fact, many of the collections we purchase come from families who have the responsibility of disposing of collections left to them by relatives.
