Mexico 1978 20 centavos

from the Mountain Groan Collection

The stress of inflation in the 1980's as Mexico squandered her oil bonanza caused many coin types to come and go. This type was introduced in 1974 and lasted until 1983, when it was superseded by a bronze type (KM 492) which lasted until 1984. Francisco Madero, martyr of the Revolution, appears on the obverse.

Recorded mintage: 527,950,000.
