Æ29 - Antoninus Pius L Δ

Year 4 of Antoninus Pius corresponds to 140–141 AD, and Alexandrian bronzes from this reign are notable for their exceptionally diverse reverse typology — the imperial mint at Alexandria operated with unusual iconographic latitude compared to Roman provincial mints elsewhere, drawing heavily on Egyptian religious tradition. The "L Δ" regnal year notation is characteristic of Alexandrian civic dating, a papyrus-rooted convention carried into metal.
