MEXICO. Mint Error -- Struck on Aluminum-Bronze Planchet -- 20 Centavos, 2009-Mo. Mexico City Mint. PCGS MS-64.
KM-395. Small type. Possibly struck on the aluminum-bronze center of a Peso coin, it is difficult to tell the exact origin of the planchet without having a measurement of its weight. Certainly an obtainable Mexican error that aficionados will treasure.
Estimate: $150 - $300
