Aureus - Victorinus Cologne

Victorinus ruled the Gallic Empire for less than two years before being murdered in 271 AD — reportedly by one of his own officers, possibly motivated by a personal grievance rather than any political conspiracy. His Cologne mint continued producing aurei of respectable gold quality even as the broader Roman monetary system was collapsing into the catastrophic debasement of the antoninianus. The aureus itself, by this period, had become almost a prestige denomination, struck in limited quantities for donatives and high-level transactions rather than everyday exchange.

RIC V.2 #10 places this among the earliest issues of his reign.
