Year 8 of Antoninus Pius corresponds to 144–145 AD, a period of studied administrative calm in Egypt — the province ran on its own closed currency system, meaning Roman silver could not circulate there without being exchanged at Alexandria's state banks and reissued as local bronze. The Alexandrian mint was effectively a monetary chokepoint for one of Rome's wealthiest provinces, and its output was tightly controlled by the prefect rather than the emperor directly.
At 34mm this is among the larger bronzes of the Antonine Alexandrian series, catalogued under Emmett IV.4#828.
