Mexico 100 Pesos Silver Coin (1977-1979): product overview
Silver during Mexico’s changing peso era
Mexico changed the metal content and denominations of its coinage repeatedly during the twentieth century. Silver one-peso issues belong to a different format from the silver hundred-peso coins introduced in 1977. Read the denomination and date range together when comparing these products; the word peso alone does not specify a silver amount.
