500 Soles de Oro

Thomas De La Rue printed this series for Peru across a seven-year window that encompassed significant monetary stress — by the early 1970s, inflation was accelerating sharply under the Velasco Alvarado military government, and the 500 Soles denomination, once a substantial sum, was losing purchasing power faster than new printings could be distributed. The note's longevity as a type reflects not monetary stability but the difficulty of reforming a circulating series mid-crisis.

Peru replaced the entire Sol de Oro system with the Inti in 1985, at which point surviving 500 Soles notes became obsolete overnight.
