Tetradrachm - Diocletianus Tyche on a bed

Diocletian's first regnal year in Egypt — Year 1 of his reign, running from August 284 into summer 285 — marks the opening of one of the most administratively transformative periods in Roman Egypt's history. He would later, in 296–297, crush a revolt there and fundamentally restructure the province, ending the long tradition of a separate Alexandrian currency system entirely. This tetradrachm belongs to the last chapter of that tradition, struck just as the man who would eventually kill it took power.
