Obol of Viennois - Amadeus IX

Amadeus IX, who ruled Viennois as Dauphin under Savoyard authority during this period, suffered from severe epilepsy — a condition that progressively incapacitated him and left effective governance largely in the hands of his wife, Yolanda of France. The obol's narrow date window reflects the political instability of his reign rather than any deliberate monetary reform.

The Dy féodales reference 2729 places this among the feudal issues catalogued by Duplessy, where Savoyard fractional silver of this era is consistently underrepresented in surviving collections.
