Æ32 - Marcus Aurelius L Ζ

Year 7 of Marcus Aurelius's reign coincided with the tail end of the Antonine Plague's first devastating wave, which had been carried back to Egypt by troops returning from the Parthian campaign. Alexandria's mint continued operating through the outbreak, though the city's population — already dense and medically vulnerable — suffered acutely. The regnal year date, expressed as L Ζ in the standard Alexandrian system, places this coin precisely in 166/167 AD by the Egyptian calendar.
