20 Nummi - Mauricius Tiberius Antioch

Mauricius Tiberius inherited an empire financially exhausted by his predecessor Tiberius II's extravagant donatives to the army and populace. His reign saw a systematic attempt to restore fiscal discipline, which included tighter control over provincial mints — Antioch among them. The Antioch mint during this period is notable for producing coins of markedly inconsistent fabric, a product of chronic copper supply disruptions tied to ongoing warfare with Persia on the eastern frontier.

Khusrow I's armies had already ravaged the Syrian hinterland in the preceding decades, and Antioch itself had been sacked in 540. The mint never fully recovered its earlier output regularity.
