Charles & Johanna "Late Series" 4 Reales ND (1542-57) M-L/S XF45 NGC, Mexico City mint, KM0018, Cal-84, Nesmith-86a. 31.5mm. Well-centered with full legends and moderate gray-toned surfaces that possess pale iridescent tone around many of the raised surfaces. Close inspection of the 'L' assayer initial shows remnants of an underlying 'S' (possibly Rodrigo Gomez de Santillan). Very rare as such, with only two known to our knowledge, this being easily the finest.
