100 Pesetas - Alfonso XIII 3rd portrait

The Cal#1 designation here is not ceremonial — Calicó's rarity classification places this as the single most significant issue in the 19th-century Spanish gold series. Alfonso XIII was only eleven years old when the dies for his first portrait coinage were prepared under the regency of his mother María Cristina of Austria; by 1897, a third portrait was already required to reflect the king's adolescent features, a progression that makes his portrait sequence unusually well-documented among European monarchs of the period.

Mintage figures for this type are exceptionally low. Most surviving examples are cabinet pieces that never reached commerce.
