Nummus - Licinius I IOVI CONSERVATORI, Thessalonica

Licinius I struck this type heavily at Thessalonica in the years immediately following the Edict of Milan, during which he and Constantine briefly governed as co-emperors before their relationship collapsed into open warfare by 316. The IOVI CONSERVATORI reverse was Licinius's ideological signature — he leaned emphatically on Jupiter as divine protector while Constantine was already gravitating toward Christian patronage, making the two emperors' coin types an inadvertent record of the religious fault line splitting the empire.

RIC VI 49A is among the more frequently documented issues from the Thessalonica mint of this period, the officina letter in the exergue placing individual pieces within the workshop sequence.
