Æ31 - Macrinus C I F SINOP AN CCLXI

Sinope's civic bronze coinage under Macrinus is dated by the local Pontic era, with AN CCLXI corresponding to year 261 of that reckoning — a calendar system the city maintained stubbornly through successive imperial reigns. The abbreviation C I F marks Sinope's status as a Roman colonia, a distinction granted under Julius Caesar, who refounded the city in 47 BC after its earlier destruction.

Macrinus ruled less than two years before being killed in 218 AD, making provincials struck in his name a narrow window of production.
