Watch List notes:

Santiago, Chile, 1/4 real, 1790, NGC MS 64 ("top pop"). Cal-181; KM-43. Bold full details with muted luster, slightly off-center strike, highly desirable top-grade example of a popular two-year transitional type within a rare series of bust-bearing cuartillos, currently tied with one other for finest in the NGC census.

Estimate: $1000 - $1500
