20 Pesos

Chile's gold 20 Pesos series coincided with a period of extraordinary national wealth driven by nitrate revenues following the War of the Pacific (1879–1884), in which Chile seized the Atacama territories from Bolivia and Peru. The Santiago mint's output expanded considerably on the strength of that windfall. Production continued into the early twentieth century before collapsing as nitrate markets began their long decline under competition from synthetic fertilizers developed in Germany after the Haber-Bosch process was commercialized around 1913.

The series runs across multiple date points through 1917, with some years seeing dramatically lower output than others — a reflection of fluctuating export revenues rather than any minting disruption.
