Archaeological excavations of the acropolis of the ancient city of Cossyra (modern Pantelleria) have been in progress for over twenty years now. Coin finds from this site offer new insights into the monetary circulation on the island, assisting attribution of some coins to the mint of Cossyra. Coins with the name of the island in the legend exist in Punic and Latin letters, but the date of this change of language is uncertain: was it associated with the Roman conquest of the island in 217 B.C., or is this change unrelated to this development? Furthermore, the coin finds have helped attribute some coins of uncertain mints to the workshop of Cossyra. How do these coins relate to those previously known? Some coins can be dated using the excavated evidence, but the coinage of Cossyra is still in need of a more extensive analysis.
