50 Colones

El Salvador's Banco Central de Reserva had relied on Thomas De La Rue for its higher-denomination printings through much of the mid-to-late twentieth century, a relationship that kept production quality consistent even as the country lurched toward the civil conflict that would define the 1980s. The 50 Colones was not a note that saw much ordinary commerce — at that denomination it circulated primarily in business and banking transactions, which means heavily worn examples are rarer than the survival rate might suggest.

The P#131 series spans two dated years with three-signature configurations for each, but the actual signatories remain unconfirmed across both runs — a gap that occasionally complicates attribution when signatures differ visibly between individual notes.
