The Golden Eagle is the official bird and symbol of Mexico, and its imagery dates back to pre-Colombian codices of the Aztecs. However, it is very likely that the actual bird is the Northern Caracara, a falcon.
Between 1905 and 1983, Mexico issued nine different 50-centavos coins. The first five were silver, each getting progressively smaller. This is the third issue, containing .1929 ounces of silver.
