5 Soles de Oro

The P#76 series was produced during a period of relative monetary stability in Peru — the Soles de Oro had been the national currency since 1931, and by the mid-1950s the Banco Central de Reserva was issuing notes with enough confidence in De La Rue's security standards that a single watermark sufficed. No serial number prefix changes or known major printing variants distinguish this run, which makes date-letter tracking the primary tool for narrowing issue windows within the 1956–1960 span.
