MEXICO. Mint Error -- Off Metal Strike, Struck on Aluminum-Bronze Planchet -- Peso, 2019-Mo. Mexico City Mint. PCGS MS-61.

KM-603. This intriguing mint error places a Peso on an aluminum-bronze planchet. This planchet also suffers from extreme evidence of friction from some harsh abrasive, but escapes the details holder by being done at the mint. One of the weirdest pieces this catalogers has ever seen, as it appears to be the first recorded case of pre-minting harsh cleaning. 

Estimate: $60.00 - $100.00
