Æ23 - Hadrian L Ϛ

Year 6 of Hadrian's reign corresponds to his first major tour of the eastern provinces, a journey that reshaped imperial policy across Egypt and the Levant. The Alexandrian mint was among the most prolific and technically sophisticated in the Roman world, operating on a regnal-year dating system unique to Egypt — the "L Ϛ" denoting the sixth year by that local convention rather than any Roman consular reckoning. Egyptian bronzes of this period circulated almost exclusively within the province, never leaving due to Ptolemaic-era currency isolation rules Rome chose to maintain.
