Silver Twentieth-Ounce Libertad, Coin Type from Mexico - detailed information

The obverse of the coin shows at its centre the Coat of Arms of Mexico, which depicts a Mexican (golden) eagle perched on a prickly pear cactus, facing left, devouring a rattlesnake. The cactus is on a pedestal immersed in the Aztec symbol for water. Below, a wreath of oak and laurel leaves tied at its centre with a ribbon representing the flag of Mexico.

The design is rooted in the legend that the Aztec people would know where to build their city once they saw an eagle eating a snake on top of a lake. To the people of Tenochtitlan (the pre-European capital), this symbol had strong religious connotations, and to the Europeans it came to symbolise the triumph of good over evil (with the snake sometimes representative of the serpent in the Garden of Eden).

Around above, the legend ESTADOS UNIDOS MEXICANOS, meaning United Mexican States in Spanish - which is the full official name of Mexico.

The border is toothed, with staggered sizes of the teeth.

The reverse of the coin shows at its centre the statue of Nike (the Greek goddess of Victory, in Spanish: Victoria) from the Angel of Independence monument in Mexico City - commonly known simply as The Angel. She is represented as a young bare-breasted winged woman holding a laurel wreath in her outstretched right hand, and a broken chain (a symbol of freedom) in her left hand. Visible below the figure is the pedestal which tops the monument.

The volcanoes Popocatépetl and Iztaccihuatl can be seen in the background.

Around above, interrupted by the wings of the angel, the inscription 1/20 ONZA PLATA PURA [year] LEY .999 (one twentieth of a troy ounce of pure silver with purity 99.9%).

The Mo mint mark of the Mexican Mint (large letter M above which a small o) is in the upper right field.

The border is plain.
