Æ25 - Caracalla ΤΙΑΝΩΝ

Tium was a minor coastal city on the Black Sea shore of Bithynia, historically overshadowed by its more powerful neighbors Heraclea Pontica and Nicomedia. Its civic bronze coinage under Caracalla is scarce precisely because the city's municipal mint operated intermittently and at low volume — surviving examples tend to appear in small numbers even in major reference collections.

The ethnic inscription ΤΙΑΝΩΝ, rather than the fuller ΤΙΑΝΩΝ or a more elaborate civic formula, reflects the abbreviated conventions common to Bithynian provincial issues of this period.
