Blanca - Juan II Toledo

Juan II inherited the Castilian throne at age two in 1406, meaning the earliest blancos struck in his name were authorized entirely by regents — first his mother Catherine of Lancaster and his great-uncle Fernando de Antequera, who governed jointly until Fernando's election as King of Aragon in 1412. The Toledo mint was among the most active of the Castilian workshops during this regency period, producing billon coinage under conditions of divided royal authority that occasionally introduced inconsistencies in die preparation and alloy composition.

AB#629 encompasses a span of over two decades, so attribution to a specific administrative phase requires close attention to mint mark placement and the particular letterforms used by Toledo celators of the period.
