Cordoba, Argentina, 2 reales, 1844, CONFEDERADA, dot under rosette, NGC MS 63 ("top pop"). Janson-48.2.18; KM-23. From a complicated series of five groups differentiated by many minor details (including styles of castles and numbers of sun-rays, this one falling under Janson's Type I Group b), with rather lustrous fields around full but slightly crude details, tied with two others for finest in current NGC census.
Estimate: $200 - $300
