Nummus - Constantius II VOT XX MVLT XXX, Heraclea

The VOT XX MVLT XXX coinage of 347–348 was struck to mark Constantius II's twentieth regnal anniversary — the *vicennalia* — with the vow legend promising fulfillment of those vows and anticipating a thirtieth. Heraclea was one of the empire's most productive mints at this period, reorganized under Diocletian and consistently active through the Constantinian dynasty. RIC VIII 54 is well-documented but not especially rare; the Heraclea mint used multiple officina marks during this issue, and the specific officina letter on a given example is worth checking against LRBC 963 for precise attribution.
