Æ34 - Antoninus Pius L ΔΕΚΑΤΟΥ

The L ΔΕΚΑΤΟΥ inscription marks this as a Year 10 dating under the Egyptian regnal calendar, placing it squarely in the middle of Antoninus Pius's reign — a period of notable administrative stability in the province. Alexandria's imperial bronze coinage was produced under the authority of the Roman prefect of Egypt, a province so strategically sensitive that Augustus had barred senators from entering it without imperial permission, a restriction still in force under Antoninus.

Alexandrian bronzes of this size circulated exclusively within Egypt; Roman law prohibited their export, keeping the provincial currency isolated from the broader imperial economy.
