1/4 oz Gold Mexican Libertads One of the most beautiful coins in the world, the Mexican Gold Libertad is .999 fine (except 1981-1988 - .900 fine). The obverse features the Mexican National Seal with the official name for Mexico in Spanish: "Estados Unidos Mexicanos." The reverse depicts two key symbols of the Mexican people: the Winged Victory statue in the forefront and the Mexican volcanoes Popocatépetl and Iztaccíhuatl in the background. The Angel of Independence statue is the main historic monument for the Mexican people and is considered the symbol of Mexico City. The Mexican volcanoes memorialize the legend of the two lovers for whom they were named.
