Drachm

Herakleia Pontika was a Milesian colony on the southern Black Sea coast that punched well above its weight as a minting authority, largely because it controlled the Pontic grain trade and needed reliable silver coinage for commercial exchange with inland Paphlagonian and Bithynian markets. The city's most politically turbulent decades — including the tyranny of Klearchos and his successors, who ruled from roughly 364 to 289 BC — fall squarely within this issue's date range, meaning this drachm almost certainly circulated under autocratic administration rather than the democratic civic government that preceded it.

The light weight standard reflects a local Pontic convention rather than Attic or Aeginetan norms.
