This is the fourth medal issued by the American Numismatic Society. It was the membership medal that was handed out to most members. Different prices were charged to those who had subscribed to the cost of the dies and those who wanted to purchase the medals afterwards. Subscriber prices were $50 for the medal in gold, $5 for silver and $1.50 for bronze.
The bronze piece shown is engraved to Alfred Rowell. As best as I can tell he practiced law in New York City.
The silver piece shown is engraved to A. J. Drexel Biddle who was the subject of a novel (written by his daughter), which was adapted both as the Broadway play and as a Disney motion picture titled The Happiest Millionaire.
The circular medal measures 42mm in diameter. It was struck in gold, silver and bronze in unknown mintages.
