RSC67  Obv: Radiate bust draped to right. “IMP CAU C VIB TPEB GALLVS AVG” . Rev: Libertas standing with crossed legs leaning on a column and holding a sceptre and lantern. The obverse legend has been misspelled. The E in CAE (Caesar)is broken and looks like a U while the R in TREP is definitely a P.  Throughout his reign barbarian invasions as well as Sassanian attacks in the east continued to destabilize and fracture the Roman empire. As barbarian attacks and civil unrest increased, Gallus and his son and co-emperor, Volusian were more than happy to enjoy the good life in Rome and let others do their fighting. However, the absence of battlefield glory in the imperial resume did nothing to inspire confidence and resulted in the rise of a powerful military commanders, who aspired to become emperor with the support of their legions. One of these usurpers was Aemillian, who marched on Rome with a large force in August 253. Gallus and Volusian marched out to meet him, but died before the battle began, murdered by their own troops who realized they were vastly outnumbered.  A nice coin, some rubs, but portrait is sharp.  EF
