Bolivia 1769-PTS JR 8 reales
"1769. Potosí. JR. 8 reales. Columnario. 9 curvo. Parte de brillo original. Escasa. MBC+. (eight reales of 1769, Potosí mint, pillar type, curved 9. Lustrous, scarce, choice very fine.)"The year 1767 marked the initiation of milled coinage at Potosi, the last mint to do so, but cobs continued to be produced until 1773. The SCWC lists "fancy 9" and "round 9" varieties for this date; this is a "round 9." This type was struck 1767-70 and is fairly available in circulated condition. Gilboy lists this date as "scarce" whereas the 1769 is "normal" and the 1770 is "common."
