Dobla of 20 maravedis - Pedro I

Pedro I — called "the Cruel" by his enemies and "the Just" by his supporters — struck these doblas during a reign defined by civil war against his illegitimate half-brother Enrique de Trastámara. The conflict, which drew in English archers under the Black Prince on Pedro's side and French routiers under Du Guesclin on Enrique's, was as much a dynastic struggle as a proxy war between competing European powers. Pedro was murdered at Montiel in 1369, and the Trastámara dynasty that followed systematically suppressed his monetary legacy, making surviving gold issues from his reign scarcer than mintage circumstances alone would suggest.
