AR24 - Hadrian L Γ

Year three of Hadrian's reign coincided with his consolidation of a radically different imperial policy from Trajan's — abandoning newly conquered Mesopotamia and pulling Roman forces back to defensible frontiers. Alexandria, as the administrative and economic capital of Egypt, was acutely sensitive to these shifts; Egypt's grain supply directly funded imperial ambitions, and the provincial coinage issued here operated under a closed currency system that forced all incoming silver to be reminted at a deliberately debased local standard.

The Alexandrian tetradrachm, though struck in silver, carried a fineness well below the contemporary imperial denarius — a fiscal arrangement Rome maintained deliberately to prevent currency arbitrage across the Egyptian border.
