The first Etruscan coins date to the late sixth or early fifth century BC and appear to have been struck in the Populonia/Vulci area. These early coins carry the letters thezi, together with a gorgon, sphinx, or various forms of lion. Regular coinage appears to have developed in Populonia in the later fifth century and in the fourth or third century BC in other Etruscan cities. There were also series of molded (rather than struck) coins from cites such as Volterra and Tarquinia.
