On the obverse, an athlete standing on some steps, holding in his right hand a laurel crown, symbol of victory, and raising his left arm. In the background, a bas relief illustrating the sports disciplines from Antiquity. Behind, a Greek temple. Above the figure of the athlete, the inscription "OLYMPIAD" and on the rock bottom right "1904". On the reverse, the goddess Nike, goddess of victory, standing on a globe. She is holding a laurel crown in her left hand and a palm leaf in her right hand. In front of her, a great crown, with in the centre a space for putting the name of the sports discipline. Behind Nike, the bust of Zeus on a plinth. The inscription "UNIVERSAL EXPOSITION ST.-LOUIS U.S.A". The design of these two sides was inspired by the medal of the 1896 Athens Games and 1900 Paris Games.
