Nummus - Constantine I D N CONSTANTINI MAX AVG, Thessalonica

RIC VII 117 from Thessalonica falls within Constantine's post-Licinius propaganda push, when the eastern mints were being systematically brought to heel following the conflicts of 316–317. Thessalonica had only recently been ceded to Constantine under the terms of that settlement, and the mint's output in this period reflects an abrupt shift in titulature as Constantine consolidated the D N ("Dominus Noster") formula — a form of address borrowed from the Dominate tradition and increasingly favored to project autocratic authority over the old Tetrarchic collegial style.
