1/2 Real - Felipe IV

Felipe IV's Navarrese coinage occupied a legally distinct space from his Castilian issues — Navarre retained its own monetary ordinances under the crown union, and the Pamplona mint operated under fuero privileges that Madrid could not simply override. The 1652 date places this squarely within the disruptions of the Franco-Spanish War, when silver supplies and mint operations across Iberia were under chronic strain.

Cayon's attribution Cal#1157 covers a small and poorly documented series, and genuine examples with legible dates are not easily found.
