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.
This large silver peso was issued from 1920 to 1945. As with all Mexican silver coins, it has the purity of the silver (0.720) engraved on the obverse of the coin. At 16.7 grams, that means this coin contains 0.3856 ounces of silver.
