Tetradrachm In the name of Alexander III

Sinope's adoption of the Alexander-type tetradrachm decades after the conqueror's death reflects the city's shifting political allegiances during the Wars of the Diadochi and their aftermath. By the early third century, posthumous Alexander coinage had become essentially an international trade currency across the Black Sea littoral, and Sinope — already one of the most commercially active ports on the Pontic coast — issued under that convention rather than in its own civic types.

The Mektepini reference places this among a group attributed through die studies specific to the Sinopean mint. Control marks distinguishing local issues from the broader posthumous Alexander series are the primary basis for that attribution.
