Nummus - Delmatius GLORIA EXERCITVS, Alexandria

Delmatius — full name Flavius Julius Delmatius — was a nephew of Constantine I elevated to Caesar in September 335 as part of the emperor's late dynastic reorganization, which parceled the empire among five Caesars and heirs. He held the title for fewer than two years. Upon Constantine's death in May 337, Delmatius was killed in a coordinated purge carried out by the army, almost certainly with the tacit approval of Constantine's three surviving sons, who eliminated every collateral male relative capable of contesting the succession.

His coins are consequently rare by structural necessity — minted across a window of roughly eighteen months at Alexandria's workshop before the purge ended both his life and his issues.
