Tium was a minor Bithynian coastal city whose civic coinage under Antoninus Pius reflects the broader phenomenon of provincial mints leveraging imperial portraiture to assert local identity — the city's name derives from the mythological Tios, son of Paphlagonos, a genealogy the civic authorities apparently took seriously enough to advertise on bronze. Issues from Tium are sparsely represented in major collections, and die studies suggest extremely limited production runs, consistent with a small polis minting primarily for local religious and market use rather than regional circulation.
