Æ20 - Caracalla ΑΚΜΟΝΕΩΝ

Acmonea was a Phrygian city whose civic coinage under the Severans was tied closely to the conventus system — Roman judicial circuits that doubled as administrative anchors for provincial mint activity. The city had a long tradition of autonomous bronze production, but issues under Caracalla reflect the period after his joint reign with Geta, before Geta's murder in 211 collapsed the dynastic arrangement entirely. Whether this piece predates that rupture or follows it cannot be determined from reign-span dating alone.
