Who Is Rare Coins of New Hampshire?

David Carleton, President

David Carleton, President and numismatist at RCNH started collecting coins when introduced to the hobby by his father and grandfather in the 1950's.  After a lull he began buying Krugerrands in 1976 and sold at the height of the market in 1980, this sparked a six year collecting binge that culminated in David meeting Warren, his future business partner and mentor.  After working together for several years both left the firm they were working with and started RCNH in 1990.
