Bolivia 1776-PTS JR 4 reales
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 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.
