1 Real 'Dieciocheno' - Felipe IV

The dieciocheno — eighteen maravedís in value — was a distinctly Valencian denomination, permitted under the fueros that granted the Crown of Aragon's territories considerable latitude in managing their own monetary affairs. Felipe IV's prolonged reign coincided with Castile's increasingly desperate attempts to extract war revenue from the peninsula's eastern kingdoms, a pressure the Valencians resisted through those same foral privileges until their abolition lay nearly half a century away.

The Valencia mint operated with intermittent intensity during these decades, its output shaped more by local credit conditions than royal decree.
