Mexico 1921-M centavo
This centavo is a better date of a type struck 1905-49. As such, the type had the longest run of any coin type in twentieth century Mexico. This date is scarce but not rare. In 1950, the centavo was downsized and changed to brass (KM 417) in which form it was issued until 1973, long after it had ceased to have any purchasing power.
Recorded mintage: 3,470,000.
