Ancient Coinage of Bithynia, Dia

Note: Imhoof-Blumer, in Griechische Münzen, stated that coins attributed to Dia, Bithynia are misread or misinterpreted, that Dia, Bithynia struck no coins and that coins with the legend DIAS should be attributed to Kabeira, Thrace - which was once called Diospolis. However, all other old and modern authors and catalogers of Bithynian coins (Waddington, Hoover, Mionnet, Babelon, Dalaison etc) do not agree, especially with regard as to where such coins are found.
