There is another group of provincial Roman coins that depict the bust of Athena alone. In this depiction she is wearing a Corinthian helmet with a "wave" of hair upon her forehead.[1] These coins date from the first half of the second century CE to the second half of the third century CE and are considered to be the most common. Since more coinage depictions of Athena wearing a Corinthian helmet have been found as opposed to those that depict her with an Attic helmet, it is thought that the Corinthian were a more popular representation.[3]
