Dikaia was a small coastal settlement on the Chalcidic peninsula, almost certainly a Eretrian colony, and its autonomous coinage was produced during a narrow window before Macedonian and later Athenian pressures absorbed the region's political independence. The city disappears from the numismatic record shortly after Xerxes' invasion corridor cut through the northern Aegean in 480 BC, making issues from the later end of this date range particularly difficult to attribute with confidence.
