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 Games in Athens and 1900 Games in Paris. For the first and only time, the medal was attached to a coloured ribbon with a pin to fix it to the athlete’s chest.
