D. Barag, ‘The legal and administrative status of the port of Sebastos during the early Roman period’, in A. Raban and K.G. Holum, Caesarea Maritima. A retrospective after two millennia (Leiden, 1996), pp. 609-14, distinguishes, for Agrippa, Claudius and Nero, between coins referring to the city of Caesarea and those referring to its port, Sebastos. He regards them as two distinct legal entities, even though he cites no parallel for this arrangement (see also 4847-8, 4862-5).
