Major mints: Kanatha, Gadara, Philadelphia.

Ten cities in modern Israel and Jordan, they were grouped into the Decapolis by Pompey the Great in 63 BC. The list is: Abila, Antiocheia ad Hippum; Kanatha, Capitolias, Dium, Gadara, Gerasa, Pella, and Philadelphia (mod. Amman, in Jordan). The coinage of this area is nearly all imperial; a few autonomous bronzes were issued at Gadara.

Gadara, the most important of these towns, was known for a few minor Greek cultural figures, such as the poet Meleager and the satirist Menippus. It is better known from an account in the New Testament; the unclean spirits expelled from a madman were sent into a herd of swine, which then drowned themselves; hence the term Gadarene swine, probably referring to this town rather than to another with a similar name.
