Æ16 D D

Tyndaris was a Sicilian Greek city founded by Dionysius I of Syracuse in 396 BC as a settlement for Messenian refugees, and it remained one of the last holdouts of Greek civic identity on the island under Roman provincial administration. The D D abbreviation in the type designation refers to a decreto decurionum — by decree of the town council — marking this as a locally authorized bronze issue rather than a Roman imperial emission, a distinction that mattered deeply to communities still asserting municipal autonomy during the late Republican period.
