These looks similar... AE 14; Peloponnesus, Sicyon; c. 303 BC, AE 14, 3.51g. BCD-315.3. Obv: Dove flying l. Rx: ?? wreath. https://www.coinarchives.com/a/lotv...&Lot=344&Val=930d4f01b1ca349c7a4621726ef193fe https://www.coinarchives.com/a/lotv...9&Lot=32&Val=713e86c36f196aef7227f3b7da71bb58
My first thought was also Sikyon, and the coin definitely matches the one in the first link provided by Spaniard. My expertise is way below many members of this group, so take my next comment with at least half a shaker of salt, but the letters on the reverse are also found on coins of Delos.
