Welcome to Dr. Robert Friedman and Sons Stamp and Coin company, the country's largest buyer and seller of valuable stamp and coin collections for over 40 years.
We can immediately travel anywhere in the country to you for valuable collections from either of our 2 locations - from Chicago or Southeast Florida. Immediate, on-the-spot payment is always made and we always pay the highest possible prices for collections.
If you have a valuable collection for sale, you've come to the right place.

Dr. Robert Friedman & Sons enjoy a reputation throughout the philatelic and numismatic hobbies as the MAJOR BUYER of any valuable stamp and coin collections. No collection should be considered too large, bulky or disorganized as we often purchase collections and accumulations in the six figures that require a moving truck to transport.
Dr. Friedman has huge financial resources.

Our financial resources allow for the purchase of the most expensive collections valued into the six or seven figures. $5,000,000 in immediate cash is generally available for the purchase of valuable collections. We have purchased well over $30,000,000 of collectibles over the last 10 years.
