10 Nummi - Justinian I CONCORDI, Antioch, ΘYΠOΛS, Bust Right

Justinian I's decade-long revision of Roman law culminating in the Corpus Juris Civilis was financed partly through aggressive fiscal reorganization, including tight control over bronze coinage production across eastern mints. Antioch — here identified by the ΘYΠOΛS mintmark, a Greek rendering of Theopolis, the name Justinian himself imposed on the city after the catastrophic earthquake of 526 AD destroyed much of it.

That renaming was a deliberate act of imperial piety, recasting a ruined city as "City of God." Coins bearing the Theopolis mark therefore postdate 528 at the earliest.
