Æ18 - Severus Alexander ΤΙΑΝΩΝ

Tium was a minor coastal polis on the Black Sea shore of Bithynia, and its civic bronze issues under Severus Alexander are among the least-documented of the provincial series — surviving references remain sparse, and die studies for this mint are essentially nonexistent. The ethnic ΤΙΑΝΩΝ confirms the civic attribution, distinguishing Tium's output from the far more prolific neighboring mints at Nicaea and Nicomedia.
