1/2 Real - Ferdinandus V and Elisabet I Burgos

Issued under the joint authority of Fernando II of Aragon and Isabel I of Castile, this coin predates the formal unification of the Spanish kingdoms — the two monarchs ruled their respective territories separately, and coins struck in their names reflected a dynastic alliance rather than a single crown. Burgos was among the most important mints of Castile throughout the 15th century, holding a privileged position in royal coinage production. The Cal#421 attribution places this within Calicó's classification of the Reyes Católicos coinage, a series notoriously difficult to sequence precisely due to inconsistent die dating across mints.
