MEXICO. Peso, 1866-Mo. Mexico City Mint. Maximilian. PCGS MS-64 Gold Shield. KM-388.1. Impressively original, this near-Gem Peso displays deep multicolored tone on the obverse that is mostly smooth over the surfaces, while the reverse presents a more mottled appearance. Beneath the tone, few marks are seen, and the designs remains impeccably sharp. <strong>VERY SCARCE</strong> quality for this issue, so much so that PCGS has only graded six examples at this lofty grade, with a single coin having been deemed finer.
