80 Réis - Pedro II Rio de Janeiro and Pernambuco Mints

These pieces belong to the earliest phase of colonial Brazilian minting, produced under the authority of Pedro II of Portugal at a moment when the Crown was scrambling to supply an adequate circulating medium for its South American territories. The Rio de Janeiro and Pernambuco mints operated with chronic inconsistency in die preparation and planchet quality during this window, which is why the Bentes reference breaks this short three-year type into nine distinct subvarieties per mint — small differences in crown punches, numeral placement, and assayer marks that have kept specialists arguing for decades.
