MEXICO. 4 Maravedis, ND (1542)-oMo. Mexico City Mint. Carlos & Johanna. PCGS Genuine--Environmental Damage, VF Details. KM-3.1; Cal-25; Nesmith-1A. Variety with "M - 4" on obverse and "oMo" on reverse. A rather pleasing exemplar of this early Mexican copper issue. While slight roughness and encrustation resulted in an "environmental damage" designation, the coin presents strong detail and attractive brown patina overall.
