Charles & Johanna "Early Series" 4 Reales ND (1536-42) R/·M·-·M· XF Details (Surface Hairlines) NGC, Mexico City mint, KM0016, Cal-72, Nesmith-6d. 32mm/13.4g. Rhomboid variety. The design is slightly doubled in places and the color varies from silvery to moderate gray. Likely the last issue for Rincon as assayer, and especially desirable because it marks a transition from the circular motto panel to the rhomboid shape that was used by the later P-F-G assayers that produced "early series" coinage.
