Year 15 of Trajan's reign in Egyptian reckoning — the Alexandrian mint dated coins by regnal year rather than consular year, a practice inherited from Ptolemaic administration that survived well into the Roman imperial period. This particular issue falls during a stretch of intense building activity across the empire, funded in part by the spoils of the First Dacian War concluded just years earlier. The Alexandrian bronze series from this reign is large and complex, with numerous reverse types struck across multiple regnal years.
