Dinero - Fernando III Coruna

Fernando III's reign saw the most dramatic territorial expansion of the Reconquista — Córdoba fell in 1236, Murcia in 1243, Seville in 1248 — and the crown's monetary output struggled to keep pace with the administrative demands of newly absorbed territories. The dinero issues of this period were struck across multiple mints to meet that pressure, with La Coruña operating as one of the northern production centers while the military frontier pushed steadily south.

Billon coinage of this reign is frequently found debased beyond nominal specification, a reflection of chronic silver shortages rather than deliberate fraud. AB#211 is among the more commonly encountered references in the series, though condition varies sharply.
