20 Céntimos With braille

Peru's transition to the nuevo sol in 1991 followed the catastrophic collapse of the inti, which had lost virtually all its value to hyperinflation under the García administration — prices rose roughly two million percent between 1988 and 1990. The new coinage was designed from the outset with accessibility in mind, incorporating braille denomination markers, an unusually progressive decision for a Latin American mint at the time.

The KM#306.1 and 306.2 variants differ in the style of the braille dots, a detail tied to production changes at the Casa Nacional de Moneda in Lima across the decade-long run.
