Since the publication of 'An Unpublished Nummus of Constantine I of the Mint of London' by Georges Gautier in NC 152, 1992, pp. 157-60, pl. 36, 1, it has long been suspected the parallel issue of MARTI CONSERVATORI would one day turn up.
This unmarked issue, also struck at Trier, Ticinum and Aquilea, was struck from about AD 311 to mid 313 in a propitious propaganda campaign invoking both invincible Sol and Mars as the god of war, in the preparation for Constantine's the attack on Maxentius in Rome and the prospect of the annexation of Italy and Africa to Constantine's share of the empire.
