Koressia was one of several small poleis on the island of Keos, and its independent coinage issues are rare survivals from a period when even modest city-states on minor Aegean islands maintained the political apparatus to strike their own silver. The fragmentary nature of Koresian civic history — largely absorbed into Kean federal identity by the classical period — makes each attributed piece significant for what it implies about late archaic island autonomy.
