Watch List notes:

Cordoba, Argentina, 4 reales, 1852, uneven rays around sun, encapsulated NGC MS 63, finest known in NGC census. Janson-85; KM-31. 13.1 grams. Beautifully rainbow toned and lustrous, with slight weakness (but decidedly not wear) on only the very highest points, still much better than previous specimens as made from new dies from Paris that arrived in that year, yielding much a much more detailed strike, commonly seen on 8 reales but less on 4 reales. (A good comparison is Lissner's example, lot #1148 in the St. James's / CNG / Teller auction of August 2014, at a lofty MS 64 grade but with nearly flat sunface and other weaknesses.) NGC #2713825-014. Acquired from Alberto "Coco" Derman in 1975. (Estimate: $1250 - 2000)
