Watch List notes:

MEXICO. Mint Error -- Off Metal Strike, Struck on Silver Planchet -- 20 Pesos, 2019-Mo. Mexico City Mint. PCGS MS-63.

KM-Unlisted. This piece presents the Zapata type struck on a planed down silver center from a 2003 100 Pesos (KM-688) issue. Much detail from the understruck piece remains, though this cataloger will leave it to the buyer to guess how such a piece was overstruck 16 years later with surfaces milled down.

Estimate: $150 - $300
