Æ20 - Gallienus sole reign (ΑΘΗΝΑΙΩΝ)

Athens struck remarkably little civic bronze during the sole reign of Gallienus, a period when the city was still recovering from the catastrophic Herulian sack of 267 AD — an event that effectively ended meaningful civic coin production in Athens altogether. What survives is sparse, and the attribution to this narrow window relies heavily on die-linkage studies rather than documentary evidence.
