Æ21 - Gallienus (sole reign) (ΑΘΗΝΑΙΩΝ)

Athens struck remarkably little bronze coinage under the sole reign of Gallienus, and the city's civic issues from this period are poorly documented — the reference here is a collector-assigned number rather than a standard corpus citation, which reflects how thinly studied this material remains. The Herulian sack of Athens in 267 AD almost certainly disrupted or terminated local mint activity, making it genuinely difficult to establish whether any given Athenian issue from this decade predates that destruction or was struck in its immediate aftermath.
