Charles I of Savoy ruled for less than a decade before dying in 1490, and his reign was dominated by the political maneuvering of his mother Yolande of Valois and, later, his own attempts to assert autonomy over a duchy perpetually squeezed between France and the expanding ambitions of the Italian states. These ducats were struck at a moment when Savoy's monetary credibility depended heavily on matching the gold standard set by Venetian and Florentine issues circulating across the Alpine trade routes.
The four-year window reflected in the dating corresponds to Charles's personal rule after he came of age, distinct from the regency coinage preceding it.
