MEXICO. Mint Error -- Off-Metal Strike, Struck on Steel Planchet -- Peso, 2012-Mo. Mexico City Mint. PCGS MS-64.
KM-603. An astonishing mint error, this Peso though normally encountered as a bimetallic production, presents as being struck solely on a steel planchet, likely a minor. Another dramatic error from the Mexico City Mint, and one that displays both the exact and simultaneously imprecise nature of minting at the Casa de Moneda de Mexico.
Estimate: $150 - $300
