Appealing errors that--fortunately for numismatists--were able to escape the Mexico City Mint. The perfect grouping to start or enhance a Mexican error collection.
1) Mint Error -- Struck on a Peso Planchet, 1975-Mo. AU-55. cf. KM-477.1.
2) Mint Error -- Struck on a 50 Centavos Planchet, 1976-Mo. MS-62. cf. KM-477.1.
3) Mint Error -- Struck 20% Off-Center, 1977-Mo. UNC Details--Wheel Mark. KM-477.1. The wheel mark was likely caused by a rolling, bagging, or counting machine that was unable to process this abnormally shaped error.
