A nummus of the type that weighed 1/132 of a pound. It is a single coin from the Seaton Down Hoard. It was made between AD 337 and AD 340 in Rome and issued by Constantine II.
The image on the reverse of this coin is of the Emperor holding a spear and shield in a manner similar to Virtus. As Virtus is the male personification of courage and bravery, having his image combined with that of the Emperor may be designed to show that the Emperor has superior courage and bravery and, therefore, why he is a great leader for the Empire.
