10 Soles de Oro

Peru's sol-based coinage was already under pressure by 1969, with inflation steadily eroding the currency's purchasing power in the years following military reforms under the Velasco Alvarado government, which took power in a October 1968 coup. Within a decade, denominations that had seemed substantial would become effectively worthless — the entire sol system was eventually replaced by the inti in 1985 at a rate of 1,000 soles to one inti.
