Watch List notes:

Potosi, Bolivia, cob 8 reales Royal (galano), Louis I, 1727 Y, very rare, NGC AU details / holed. S-P43b; KM-R35; Cal-46. 26.83 grams. Superb full inner details and much legend for this smaller-flan period including full date and all-important LVIS PR (as noted by NGC), deeply toned all over, die-match with Lazaro 309 (rated R4, three to four known), a lovely coin despite the inevitable hole at top of pillars / left of cross, in fact second finest at NGC, bested only by an MS 61 monster in strong private hands. Pedigreed to the UBS auction of January 2001 ("Fifty Numismatic Rarities"), lot 5.

Estimate: $10000 - $20000
