Gorini supposed, on the basis of a few silver coins that were found in Rhizon which bear the long legend with the regal title, that Rhizon had been the capital of Ballaios' state. On those coins, Artemis is depicted as advancing to the left, and is similar to the goddess depicted on Acarnanian coins dated to around 200 BC. Ballaios may have well begun to mint his coins based on Acarnanian coinage designs. Political and economic relations between Illyrian monarchs and various Greek regions, as well as even marriage ties between Illyrian and Greek kings and queens were hardly exceptional. The finding of Ballaios coins along with other Illyrian and Greeks coins in Bari in southern Italy has made Gorini date the deposition of the hoard, which may have been a votive offering, to c.125 BC. Other sites where the coinage of Ballaios has been found in an archaeological context is in the city of Daorson.
