Hekte

Mytilene's electrum hektes were struck under a formalized agreement with Phokaia, the two cities alternating annual issues — a monetary arrangement unique in the Greek world and documented well enough that scholars can often assign individual types to specific years. The Bodenstedt 65 type falls within the period of Mytilene's complicated maneuvering between Athenian and Spartan interests following the city's failed revolt of 428 BC, a political reality that made stable, high-quality coinage a deliberate act of civic credibility.

The Phokaia-Mytilene agreement held for roughly a century, with the natural electrum alloy composition varying slightly by issue — a detail metallurgical analysis has used to sequence the series more precisely than ancient sources alone permit.
