Solidus - Aelia Eudoxia SALVS REI PVBLICAE, Constantinopolis

Aelia Eudoxia was elevated to Augusta in January 400 AD, a promotion driven largely by the political maneuvering of Eutropius's successor Aurelian and the general Gainas crisis that nearly tore Constantinople apart. Her coinage rights followed from that elevation — solidi struck in her name before 400 are thus issued under a more ambiguous authority, and the RIC X dating range of 397–402 brackets both her pre- and post-Augusta status.

The Constantinople mint was the dominant gold-striking facility in the East by this point, having largely supplanted Thessalonica for imperial issues of this type.
