1 Ducat - Ferdinandus II and Elisabet I two stripes

Ferdinand II and Isabella I — "the Catholic Monarchs" — ruled Valencia jointly, and Valencian ducats of this period reflect the constitutional fiction of co-sovereignty that underpinned the Crown of Aragon's composite monarchy. The two-stripe privy mark variant identified under Cru#1199 places this issue within a narrow window of the Valencia mint's production, distinguishable from closely related emissions only by that detail.

The Valencian ducat was modeled on the Venetian gold standard that had dominated Mediterranean trade for two centuries. Ferdinand's seizure of tighter control over Aragonese mint operations after 1479 pushed output upward, but surviving examples attributable to specific privy mark periods remain comparatively scarce.
