Kainon

It seems that the Issue KAINON has been issued in the Akragas area (Westermark, 1977. The 5C bronze coinage of Akragas CISN, 3-15).
This KAINON mercenaries were previously engaged by the Carthaginians.

357 BC Dion in Syracuse (oligarchis party). Philistos was another candidate.
       In opposition the democratic party of Herakleidas.
356 BC Symmachia, an alliance between Syracuse and Sicilian cities (Sikelians, 
       Sicans, Greeks).
356 BC Symmakoi conference in Leontinoi. Liberated Greek cities and (Carthaginian!) 
       mercenary settlements have also been invited, obviously to enlarge the 
       confederation.
