The obverse bears a kneeling nude inspecting two pieces of a fossil, hammer on the ground. Legend reads THE / AMERICAN NUMIS - MATIC / SO - CIETY / 1858 / 1958. There reverse bears two artisans at anvil, one holding die with tongs, other holding hammer, winged Pegasus above.
Laura Gradin Fraser wrote in the pamphlet that accompanied the medal:
"When nature petrified the first forms of animal and plant life, Nature made the first dies. The obverse of the American Numismatics Society Centennial Medal shows the potential archeologist, who, having broken a stone asunder, discovers a petrified animal form in one half and in the other a perfect impression of it, or the die."
The Pegasus represents the Arts and it lends inspiration to the artisans who are forging a medal using the simplest of tools.
This is the 48th issue by the American Numismatic Society.
The medal measures 89mm in diameter and was struck by the Medallic Art Company of New York. The reported mintage is 620 pieces in bronze.
Many thanks to the Yale University Art Gallery for permission to use its beautiful images.
