Gallienus r. 253 - 268 A.D.
antoninianus, bronze with silver wash bought at a coin show, 1989

Gallienus reigned from 253 - 268 A.D.
wt= 3.339 g

The antoninianus is a double denarius as evidenced by the spiked crown. This coin appears to be very low grade silver but I understand they are bronze with a thin silver surface coating. During this period the antoninianus declined from 20% to 4% silver. This one appears on the outside to be about 10% silver but may be less overall.

The Sucessionist Gallic Empire [Wikipaedia]

From 260 to 271 AD the NorthWest Roman Empire including Britain, Gaul, and Germania, and parts of Hispania were controlled by a rebel Emperor. This Separatist Gallic Empire was created by the general Postumus in command of Britain. The Gallic Emperors were: Postumus, Marius (just a short period), Victorinus, and Tetricus I and II.

Emperor 260 - 269 AD
double sestersius, bronze
CNG auction, ca. summer 2013
These pieces are quite common but have a huge range in weight. The exact denomination may be uncertain as one can find very heavy pieces as well as lighter ones where Postumus' Bust has the crown denoting a double denomination. I believe there is also a partially silver? denarius showing Postumus with a bare head but these are very expensive.

weight ~ 20 g ?
