Drachm Eunous - Chairillos

Dyrrachion — the Greek colony Rome knew as Dyrrachium, on the eastern Adriatic coast — issued drachms of this type in enormous quantities throughout the third and second centuries BC, functioning as the dominant silver currency for Adriatic trade. The magistrate name pairings stamped on each issue, here Eunous and Chairillos, served as a rotating accountability system; hundreds of such name combinations are recorded, making die-linked pairs useful chronological anchors within the series.

The BMC references 137 and 138 place this pairing squarely within the middle of the sequence. Dyrrachion's drachms circulated well beyond city limits — hoards have turned up deep into the Illyrian interior and as far as the Danube basin.
