Athens struck bronze coinage only intermittently, preferring silver for nearly all serious transactions well into the Hellenistic period. This issue falls within the years when Macedonian influence over Attica was finally loosening — Athens regained nominal independence after the death of Demetrius II in 229 BC, paying the Macedonian garrison at Piraeus to simply leave. Bronze filled gaps silver couldn't efficiently cover at the street level, and Kroll's sequencing places this type firmly in that post-garrison window of renewed civic minting.
