^Lot 1375 PERU, Cuzco, ½ real, 1830/28 G, NGC MS 63, finest known in NGC census, ex-O'Brien.

PERU, Cuzco, ½ real, 1830/28 G, NGC MS 63, finest known in NGC census, ex-O'Brien. KM-144.2. Strong luster, trace of incipient toning, crude centers but nice original surfaces, scarce overdate that technically does not appear in the NGC census (the present coin missed, possibly due to the age of the slab) but still finer than clean-date examples therein (which top out at XF). Pedigreed to the John O'Brien Collection, with his tag.
