Æ26 - Trajan Decius ϹΕΠ ΡΗϹΑΙΝΗϹΙωΝ L III P

Rhesaena was a Severan foundation in northern Mesopotamia — the city's coins routinely carry Severan dynastic references in their legends long after that dynasty's collapse, a provincial habit that reflected civic identity more than imperial loyalty. Under Trajan Decius, the mint was squeezed between Roman frontier anxiety and Sasanian pressure from the east; Decius himself would die fighting the Goths at Abrittus in 251, making the entire reign a brief window of roughly two years.

The "L III" in the legend denotes the third year of a local civic era, a dating convention specific to this mint's output.
