My favorite thing about numismatic databases are the things that pop up that I wasn’t looking for. This is a great example. There aren’t many known specimens, but there are two in the British Museum (example 1, example 2). Its obverse clearly echoes a much earlier republican didrachm (RRC 20/1).
It’s always interesting to see an awareness of earlier types surfacing after such an extended period–over two centuries regardless of how one wishes to date RRC 20/1. That said, it also raises questions about why this earlier type might have been attractive in this moment under Augustus. Hercules is usually associated with his rival Antony. As is Hellenistic Kingship. The connotations of the obverse type seem at odds with the Augustan program. Perhaps this explains its rarity? Perhaps the moneyer thought better of the design choice? A choice which at first which might have been attractive simply because of its antiquity and Augustus’ own rhetoric of conservative restoration?
