Æ33 - Trajan L ΙΘ

Year 19 of Trajan's reign corresponds to 115–116 AD, when the emperor was prosecuting his Parthian campaign and had pushed Roman territorial control to its furthest eastern extent, briefly reaching the Persian Gulf. Alexandria's mint continued issuing dated bronzes by regnal year throughout his reign — the L ΙΘ date formula is the Egyptian Greek convention, with L functioning as an abbreviation for "year."

The Alexandrian civic coinage operated under a distinct monetary system from the rest of the empire, functioning as a closed currency that could not legally circulate outside Egypt.
