100 Soles de Oro

The 100 Soles de Oro was part of a series the Banco Central de Reserva del Perú had been issuing under the Velasco Alvarado military government, which nationalized key industries and reshaped Peru's monetary policy through the early 1970s. By 1975, inflation was accelerating sharply — this denomination, already substantial in 1968, was losing ground fast against rising prices, and within a few years the entire Soles de Oro system would be overwhelmed by inflation requiring ever-larger denominations.

Thomas De La Rue's involvement with Peruvian currency stretched back decades, making this a continuation of a long commercial relationship rather than a new contract.
