Watch List notes:

Potosi, Bolivia, bust 8 reales, Charles III, 1777PR, NGC MS 64, finest known in NGC census. Janson-63.6; CT-978; KM-55. Choice luster and strike (especially on the reverse), with frosty details and practically no marks, incipient toning, worthy of its lofty status in the census (in fact the top grade for the whole series except for the hoard specimens dated 1774). NGC #4742985-003.

Estimate: $1000-1500
