MEXICO. 8 Reales, 1858-Go PF. Guanajuato Mint. PCGS MS-62. KM-377.8; DP-Go42. Delightful satin surfaces also reveal tinges of reflectivity in the fields as the coin dips into a light. Some characteristic weakness in the centers precludes a higher grade, though preservation is top notch. With only three finer examples listed in the PCGS population report, we expect the present coin to be eagerly sought by advanced series specialists.
