50 Soles de Oro

The Soles de Oro series of the late 1940s and early 1950s was issued against a backdrop of relative Peruvian monetary stability — unusual for the period in South America. Peru had pegged the sol tightly to the US dollar throughout much of the 1940s, and the BCRP's conservative reserve policy meant these notes entered circulation in manageable volumes rather than as inflation fodder.

De La Rue's involvement here is unsurprising; they had maintained a near-continuous relationship with Lima since the 19th century. Notes from this specific series are frequently found with significant handling wear, suggesting genuine heavy circulation rather than administrative hoarding.
