Drachm

Thasos derived enormous wealth from silver mines on the Thracian mainland opposite the island, and from a wine trade so lucrative that Thucydides — himself a Thasian landowner — documented the colony's commercial reach across the northern Aegean. This drachm series falls within a period of sustained Athenian pressure on Thasian autonomy, following the forced demolition of Thasian walls and fleet in 463 BC after a three-year siege. The island's monetary output never fully recovered its archaic scale, and fractional silver from this period circulated primarily in regional trade rather than wider Greek markets.
