During the time of Mithridates IV Eupator cities were given the authority to produce local coinage bearing their name. There were ten issuing cities in the Pontos region (Amaseia, Amisos, Chabakta, Gazioura, Kabeira, Komana, Laodikeia, Pharnakeia, Pimolisa and Taulara) and three outside of Pontos (Sinope, Amastris, and Dia). I collect very lightly in this area and have never seen that city legend before.

AMI-ΣOY -> Amisos
AMAΣ-ΣEIAΣ-> Amaseia
XABA-KTΩN -> Chabakta
Your full legend is likely "ΚΟΜΑ-ΝΩΝ" -> Komana
