Gallienus (253-268) - Billon Antoninianus - Minerva resting on spear and shield (EF)

Minerva standing right, resting on spear and shield

The antoninianus was meant to be worth two denarii, but due to the debasement of the coin it never had twice as much silver content. The metal is described as "billon", a mixture of silver and a base metal such as copper.
