This is a bronze of Caesarea showing Mt. Argaeus on an altar. My example is similar with Geta's father Septimius Severus. Oddly my coin has a very weak K in the city name where your coin has only that K and the A following remaining from the legend.
Very nice depiction of Mt. Argaeus on the OP coin, it's certainly been through a lot of hands but that is a good thing!
