The inner part of the coin depicts the conversion of Saint Paul on the road to Damascus (the city is visible in the background); the saint, dazzled by a light from the sky, falls from his rearing horse. Two inscriptions are engraved around the portrait: on the left hand side, an inscription denoting the issuing country ‘CITTÀ DEL VATICANO’; on the right hand side, the legend ‘ANNO SANCTO PAULO DICATO’. The year ‘2008’ is inscribed to the right of the portrait, as well as the mintmark ‘R’ and the artist's name ‘VEROI’. Beneath the portrait are the initials of the engraver Luciana De Simoni, ‘L.D.S. INC.’.
The twelve stars of the European flag are depicted on the outer ring.
