Bolivia 1782-PTS PR 4 reales
This is a late example of a type struck 1773-89 at Potosi, Bolivia (then called Upper Peru). It was replaced in 1791 by the bust of Charles IV. Harris 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.
