Nummus - Maximinus II as Caesar draped, cuirassed, GENIO POP ROM, PLN, Londinium

Maximinus II spent years frozen in the second tier of the Tetrarchic hierarchy — granted the title of Caesar in 305 by Galerius but denied the Augustus rank he felt owed, a slight that would eventually push him toward open conflict with his superiors. This Londinium issue dates to a particularly unstable moment in that system's unraveling, when Constantine had already been acclaimed Augustus in the same city the previous year following his father Constantius's death, a move that directly destabilized the careful succession Diocletian had constructed.

The PLN officina mark places this firmly at the London mint before its closure circa 325.
