Stater - Rhoemetalces Antoninus

Rhoemetalces ruled the Bosporan Kingdom as a client of Rome, and the gold stater series issued under his reign reflects the tight political dependency that defined Bosporan kingship throughout the 2nd century. The portrait pairing with Antoninus Pius — the reigning emperor — was not decorative convention but a political obligation: Bosporan rulers needed visible Roman endorsement to maintain legitimacy against both internal rivals and pressure from steppe peoples to the north.

The Bosporan stater had by this period diverged substantially from its Greek weight standard, a long drift that began under earlier dynasts and continued unchecked through the Roman client period.
