Our company is the largest United States company specializing in the purchase and sale of valuable stamp collections.

Our experience in determining fair market value on almost every conceivable kind of philatelic property is among the most respected in the entire profession.

Most companies can only purchase parts of a collection leaving the seller with remnants that are often difficult to sell. Dr. Robert Friedman and Sons can offer to purchase all parts of your stamp collection if you would like.

We are a professional business and take great pride in the personal attention we give to the needs of each client. Although Dr. Friedman was a senior partner in a large medical group, he has been an international dealer of valuable stamp collections for over 50 years. His son Steve who does much of the appraisals and buying joined the company in 1990 and his son Ken our chief processor joined the company in 1992.
