MEXICO. 4 Reales, 1821-Mo JJ. Mexico City Mint, Assayer JJ. Ferdinand VII. NGC MS-64. KM-102; Cal-1098. The single second finest certified of the date on either the NGC or PCGS population reports. Final year of issue. This wholly original looking example offers a pleasing appearance and displays attractive mottled patina over lustrous surfaces. Boldly struck, the devices are crisp and frosty with nicely detailed design features. A seldom encountered type in uncirculated conditions, they are <strong>VERY</strong> <strong>RARE</strong> in this elite state of preservation and highly desirable. From the Pat Johnson Collection.
