When the Carrancista Urbano Angulo took over as jefe politíco on 7 July 1915, he ordered that the paper currency used in the district should be the Carrancista Ejército Constitucionalista de México issue. However, this caused difficulties as businesses and individuals mostly held other issues such as the Monclova, dos caritas, Brigada de Sinaloa, Estado de Sonora and Cornejo, so he decided to allow those that had been validated with the resello of the Jefatura Política or Presidente Municipal, with the exception of the Villista issues (i.e. the Estado de Sonora and the dos caritas).
On 10 July it was decreed that notes revalidated by the Comandancia Militar were of obligatory acceptance in local transactions, but on 2 August a further decree suspended their circulation, leaving the Ejército Constitucionalista de México notes in circulation.
So we might expect a selection of validations but in fact these are rare, with the legend “REPUBLICA MEXICANA, LA PAZ, B. C.” known on the Ejército Constitucionalista issue.
