Selymbria sat on the northern shore of the Propontis, close enough to Byzantium to matter strategically but independent enough to strike its own silver throughout the early fifth century. The city's coinage is rare at any denomination. During the Persian Wars, Selymbrian territory fell within the operational zone of Xerxes' campaign — the royal road to the Hellespont passed near enough that Persian logistics directly affected the region between 480 and 479 BC, likely disrupting mint activity.

HGC 3.2 lists only a handful of confirmed specimens for this type.
