MEXICO. Early Series. 4 Reales, ND (1538)-R. Mexico City Mint, Assayer R (R/oMo-oMo). Carlos & Johanna. NGC EF Details--Edge Filing. KM-16; Cal-115; Nesmith-6c. Variety with Latin "R" and round panel. This handsome example exhibits a decent strike with bold details and minor doubling somewhat muddling portions of the legends and devices. The surfaces are toned a light gray color with areas of richer patination in the legends and amongst the devices. Close inspection reveals a small file mark on the edge at about 1 oclock and 8 oclock from long ago accounts for the details designation, the surfaces do exhibit a slightly granular texture mentioned for accuracy. Despite its shortcomings this handsome piece offers a pleasing appearance and this popular issue is sure to be a welcome addition to the next collection it enters. From the Pat Johnson Collection.
