CANADA. Mint Error -- Struck over Mexico 20 Pesos -- 5 Cents, 1986. Winnipeg Mint. PCGS MS-62.KM-60.2a. A very intriguing and no doubt <strong>EXEPTIONALLY RARE</strong> mint error, this type, struck upon a 5 Pesos host coin (KM-508) of Mexico. Indeed, one can even make out traces of said host. Given the fact that Canada was not striking coins for Mexico, this Potosi-based host coin would appear to be the product of mint sport.
