The medal was originally conceived by Benjamin Franklin after being asked to create a monument in honor of the Siege of Yorktown. Franklin outlined his idea in a letter to Robert Livingston on 4 March 1782.[3] The reverse design was further developed by Esprit-Antoine Gibelin and Augustin Dupré.[4]
The coin was minted in copper, silver and a couple of gold. The gold medals were lost in the French Revolution and were never found.
The obverse of the medal features the goddess Liberty. Beside her is a pole adorned with a Phrygian cap. The reverse features the infant Hercules representing the United States being attacked by a lion representing the United Kingdom. The infant, who is shown strangling two snakes, is being protected by Athena who represents France.[4][5] The reverse includes the motto NON SINE DIIS ANIMOSUS INFANS, from Horace's ode "Descende coelo", which translates to "The infant is not bold without the aide of the gods."
