Tetradrachm

Kibyra was an unusually powerful inland city for Phrygia — its tetradrachms circulated during a period when the city controlled a regional league of four towns (the Tetrapolis) and commanded enough military strength that Rome felt compelled to break it up in 188 BC after the Treaty of Apamea. The coins continued to be struck well after that political dismemberment, suggesting the city retained significant commercial weight even stripped of its confederate authority.

The issue falls within the broader Rhodian weight standard that dominated western Anatolian silver coinage after Apamea, running until Sulla's reorganization of the region following the First Mithridatic War in 84 BC.
