MEXICO. 20 Centavos, 1910-M. Mexico City Mint. PCGS MS-66.
KM-435. 1 over inverted 1 variety. Billowy satin frost stretches across the flan in a spectacular display, uninterrupted by tone or recognizable marks. One would be hard-pressed to find a better preserved example, with only one other coin encapsulated finer by PCGS (MS-66+). The best that registry set collectors can realistically expect to add to their cabinets.
Estimate: $150 - $300
