AR24 - Hadrian L Ε

Year 5 of Hadrian's reign saw the emperor make his first extended tour of the eastern provinces, a journey that reshaped imperial policy toward Alexandria. The city held special administrative significance as the capital of Rome's wealthiest grain-supplying province, and its mint operated under distinct Egyptian monetary conventions — a closed currency system that kept provincial coinage from circulating outside Egypt's borders.

The billon tetradrachm was the backbone of that closed system, debased well below true silver content by this period.
