Watch List notes:

Lima, Peru, cob 8 reales, 1690R, rosette above the denomination. S-L9; KM-24; CT-233. 27.52 grams. Bold full pillars and cross, both well-centered on a smallish flan with flat peripheries, two dates, three assayers, lightly toned AXF. From about 1688 onwards the ornament above the denomination on the pillars side alternates from a simple dot (the norm) to a four-petal rosette (scarce), but usually that ornament is not visible except on Royals (see lot 604 in this auction). This coin is a rare example with the rosette completely visible.
