Triobol

Abdera, a Thasian colony on the Thracian coast, sat on one of the more productive silver supply routes of the fifth century, drawing on Pangaion-region sources that fed Thracian and Aegean mints alike. The city's coinage from this period is notable for its rotating magistrate system — individual issues were tied to named officials, making die linkage studies unusually tractable for a mint of this size. May's 1966 corpus remains the authoritative reference precisely because the series is complex enough to reward it.
