Mexico
Charles & Johanna "Late Series" Real ND (1542-57) M-S XF45 NGC, Mexico City mint, KM0009, Cal-156, Nesmith-76. 24mm. Boldly struck, albeit a bit off-center on the pillar side, with excellent metal quality throughout. Overall, a very pleasing representative from this very elusive and obviously short-lived 'S' assayer.
