MEXICO. 10 Pesos, 1957-Mo. Mexico City Mint. PCGS MS-66.
KM-475. Commemorating the 100th anniversary of the constitution. An argent piece that, save for some speckled olive-brown patina on the upper obverse, looks as though it is fresh off the striking press. Sweeping fields are uninterrupted by chatter, nicks, or handling sometimes encountered at lower Mint State grades.
Estimate: $40 - $70
