Dobla - Juan II Burgos

Juan II's doblas occupy a transitional moment in Castilian monetary policy — the king repeatedly debased his gold coinage under fiscal pressure from the Hundred Years' War's economic spillover and his own costly internal conflicts with the Infantes de Aragón. The Burgos mint, one of the crown's most productive, struck these pieces across a reign defined less by Juan himself than by his privado Álvaro de Luna, who effectively controlled royal finances until his execution in 1453.

Luna's fall came just a year before Juan's death, leaving the mint mid-series.
