Another coin joined the series "Archeology and Symbolism".  The Coyolxauhqui Stone is an Aztec artefact in the form of a stone disc. It was discovered by accident - on 21 February 1978 it was dug up by workers laying an electricity line under one of the streets of Mexico. The place where the artefact was found is not accidental - it is the foot of the former Templo Mayor, i.e. the main temple of the Aztec capital Tenochtitlán. The reverse of the coin refers to the myth about the god Huitzilopochtli, who killed his sister, Coyolxauhqui, who rebelled against him, and then dismembered her body. The coin depicts the quartered body of the goddess with a fiery serpent entwined in it, the symbol of Huitzilopochtli. This disk was symbolic - its location at the foot of the Templo Mayor gave it both religious and propaganda significance. It showed that the dead Coyolxauhqui was resting at the foot of the main temple of the empire. The artefact is a symbol of all the peoples who rebelled against the Aztec state. The disk is currently in the collection of the Museo del Templo Mayor in Mexico. This coin was struck from 3 ounces of pure silver. Its unusual shape, large diameter and low mintage make it an excellent item for any collector.
