MEXICO. 1/2 Real, 1762-Mo M. Mexico City Mint. Charles III. NGC MS-64. KM-68; Gil-M-05-39A; Yonaka-M05-62B; Cal-1751. Deep charcoal with glints of lighter gold and mauve overtone intermingled on both sides. The strike is razor sharp over the central high points, filling out both the globes and shield nicely. Satiny and smooth, luster underlies everything, breathing potent life into this handsome survivor.
