I just picked up this coin of the usurper Eugenius.
After the death of Valentinian II in A.D. 392, there was not a ruler on the Western throne until the German general Arbogastes put Eugenius on the throne as a puppet ruler. Theodosius I did not recognize Eugenius as a legitimate co-ruler and in A.D. 394, he defeated Eugenius at the Battle of Frigidus. After Eugenius was put to death, Arbogastes killed himself.
The silver coins of Eugenius are the most common, while bronze coins are harder to find. The reverse on this one is not so clear, but Eugenius had two types with Victory advancing left- VICTORIA AVGGG and SPES ROMANORVM and these were issued from Trier, Lyons, Arles, Aquileia and Rome
