Æ31 - Trajan L ΙΕ

Year 15 of Trajan's reign in Egypt — 111/112 AD — falls squarely within the period of his Dacian wars and their enormous administrative and financial demands on the empire. Alexandrian bronze coinage operated on a closed-currency system: Egyptian provincials were forbidden from using imperial coinage directly, and coins imported into Egypt were melted and restruck at the Alexandrian mint, giving the prefecture an unusually tight monetary control that persisted well into the third century.
