AR26 - Caracalla ΔΗΜΑΡΧ ΕΞ ΥΠΑΤΟϹ ΤΟ Δ

Rhesaena was a Mesopotamian city whose brief window of coin production was entirely contingent on Roman military occupation — it struck civic issues only while the region was under Roman administrative control following Septimius Severus's Parthian campaigns. The legend ΔΗΜΑΡΧ ΕΞ ΥΠΑΤΟϹ ΤΟ Δ records Caracalla's fourth consulship, held in 213 AD, giving this piece a narrower date range than the broader reign suggests.

Billon coinage from Mesopotamian civic mints is notoriously variable in silver content, reflecting local metal supplies rather than any imperial standard.
