One interesting fact about coins minted in Mexico is that Mexico was the home of the very first mint in the Americas. One of the most popular pure silver coins in the world is the Mexican Libertad (Liberty). It contains one ounce of .999 pure silver and happens to be in high demand by lovers of beautiful coins everywhere. The coins obverse design memorializes Mexico’s war of independence with Spain by depicting a landmark statue in Mexico City, “El Angel de la Independencia.” A crown in her right hand symbolizes victory. While in her left is a broken chain representing Mexico’s freedom from Spanish rule. Located behind her are two volcanoes. The reverse of the coin displays multiple versions of the Mexican coat of arms, which is a symbol for Mexico. The center of the design commemorates the historically significant founding of Mexico City with the image of an eagle devouring a snake while standing on a prickly pear cactus; an image that was taken as a sign from the gods, by an ancient tribe. This coin is stunningly beautiful and would be a wonderful addition to any collection.
Also, the only true "proto money" to be found in the Americas pre-columbian was from the Aztecs in Mexico. They had hoe money, copper in the shape of a hoe but too thin to be a tool, so it was a representation of a hoe for currency, just like ancient China. Be careful if you ever get a copy, as they were refined with arsenic so really not safe to handle a lot with bare hands.
