Nummus - Constantinus II GLORIA EXERCITVS, Two standards, Siscia

The GLORIA EXERCITVS type with two standards was introduced empire-wide around 330 AD as a deliberate propaganda response to the increasing reliance on barbarian federates — a visual insistence on Roman military cohesion at precisely the moment it was fraying. The Siscia mint, one of the most productive in the Balkans, struck these in enormous volume, which is why survivors are plentiful but fine examples less so than their abundance suggests.

By 335, the two-standard variant was being phased out in favor of a single-standard type, a reduction whose meaning remains debated — administrative simplification or something more pointed about troop reductions in certain commands.
