With a green tint betraying its copper content, this coin is an electrotype replica created more than a century ago. It precisely replicates the form of a 2nd-century BC original. Retaining the basic scheme of Athena and owl from earlier Athenian coinage, these “New Style” tetradrachms—as scholars call them—give the goddess a more naturalistic appearance and add an amphora, olive wreath, and magistrate names to the reverse.
