Item Overview
An extraordinary, high-rarity minor silver issue from Spanish Colonial America! Struck under King Charles IV (Carlos IV) at the historic Potosí Mint in colonial Bolivia (marked by the famous PTS monogram), this 1799 1 Real is an extreme population rarity in certified holders.
Bearing the PP assayer initials (Pedro Prudencio de Esuchárraga and Pedro de Mazondo), minor denominations like the 1 Real were heavily circulated workhorse coins across North and South American commerce. Certified VG 10 (Very Good 10) by NGC, this piece stands at the very pinnacle of certified survivors on the NGC population report.
