Æ17 - Severus Alexander ΡΗϹΑΙΝΑ) Δ, LEG III

Rhesaena was a garrison town on the Khabur River in northern Mesopotamia, functioning as a key staging point for Roman operations against Parthia and later Sassanid Persia. Its civic bronze coinage under Severus Alexander is exceptionally rare — the city produced no large or sustained series, and most known specimens come from a handful of dies. The Legio III Parthica connection is specific: that legion was stationed in Mesopotamia from its foundation under Septimius Severus, and its association with this mint reflects the thoroughly militarized character of Roman Mesopotamia as a province.
