Dinero - Alfonso VIII with date

Alfonso VIII was thirteen years old when he finally wrested effective control of Castile from the competing regency factions that had spent his childhood fighting over the kingdom. The dated dinero — extraordinarily rare for Iberian medieval coinage of this period, which almost never carried explicit year markings — is thought to commemorate that consolidation of royal authority. The MOMECA corpus places this type among the earliest datable Castilian billon issues with any confidence.
