1915-S Panama-Pacific Exposition Gold Dollar. MS-66 (PCGS).,Appealing rose-gold surfaces offer full mint luster and a silky smooth appearance. The smallest gold denomination issued in connection with the 1915 Panama-Pacific International Exposition, the gold dollar has a mintage of 25,000 coins. Only 15,000 examples were distributed to contemporary buyers, however, and the remaining 10,000 pieces were melted. This is a particularly attractive Gem that is sure to please.,From the A.J. Vanderbilt Collection.,
