8 Cornados - Felipe IV

Navarre retained its own coinage system well into the Habsburg period, a privilege preserved under the terms of the 1512 incorporation into Castile. The cornado — a denomination with roots in the medieval kingdom — continued to be struck at the Pamplona mint long after equivalent petty copper had vanished elsewhere in the peninsula. Felipe IV's reign saw considerable pressure to harmonize Navarrese monetary practice with Castilian reform edicts, but the kingdom's fueros provided enough legal insulation to keep local types in production across four decades.

The unusually low weight for an 8-cornado piece reflects chronic underfunding at Pamplona rather than any deliberate policy shift.
