This is an early example of a type struck 1772-89 at Potosi, Bolivia (then called Upper Peru). It was replaced in 1791 by the bust of Charles IV. Harris[1] notes that Potosi four reales of Charles III are the commonest mint, with twice as many as Mexico City. Recent hoard finds have only increased this number. This specimen was lot 932 in Sedwick sale 25 (Winter Park, FL, May 2019), where it did not sell. The catalog description[1] noted, "Potosi, Bolivia, bust 4 reales, Charles III, 1780PR. Matte AU- with light sediment around details."
