Æ21 - Caracalla

Serdica — modern Sofia — was among the more active provincial mints in Thrace during the Severan period, striking a substantial bronze series under Caracalla across his nearly two-decade reign. The city had been elevated to the status of a municipium under Marcus Aurelius, and its civic pride in that status shows in the volume and variety of its local bronze output.

Varb. 2422 is documented in Varbanov's corpus of Thracian provincials, though die matches across this series occasionally surface that suggest smaller individual emission runs than the broad reign dates imply.
