1 Ducat - Ferdinandus II lion and S

Ferdinand II of Aragon held Valencia as a distinct kingdom with its own monetary system, separate from Castile — a jurisdictional reality that persisted even after his marriage to Isabella I united the crowns in name. Valencian gold coinage of this period was struck under the authority of the local mint, which operated with considerable autonomy. The ducat denomination itself was adopted across Aragonese territories in deliberate imitation of Venetian trade gold, a calculated move to ease commerce along Mediterranean routes where the Venetian ducat was the benchmark of trust.
