Bolivia 1807-PTS PJ 4 reales
This is a late example of a type struck 1791-1808 at Potosi, Bolivia (then called Upper Peru). It was replaced in 1816 by the bust of Ferdinand VII. Harris notes that Potosi four reales of Charles IV are the commonest mint, ahead of Mexico City. Recent hoard finds have only increased this number. Assayer PJ is recorded for 1803-25.
