Peru's Sol de Oro coinage underwent a brass substitution in the early 1960s as silver prices made the old alloy economically untenable — this 1965 issue belongs to that transitional period when the Banco Central was quietly repricing the cost of minting against a deteriorating fiscal position. The Casa de Moneda de Lima, one of the oldest operating mints in the Western Hemisphere, had been striking sols on that same site since the colonial period.
Brass issues of this denomination circulated hard through the late 1960s before inflation began its prolonged assault on the Sol de Oro's purchasing power, culminating in the currency's replacement by the Inti in 1985.
