Exceptional Mexican coins have been circulating the globe for over 4 centuries. The most current of these is Silver Libertad, first struck back in 1982 by the Casa de Moneda de Mexico (the Mexican Mint). While Mexico has issued other silver coins before this, such as the Mexican Silver Peso, this was the first coin struck by Mexico strictly for bullion purposes. Today, it is one of the most popular silver bullion coins and is collected all over the world.
The Obverse of the Silver Libertad shows an image of the current Official Seal of Mexico - an eagle with a snake in mouth, standing on a cactus. The seal is surrounded by Mexico's official name "Estados Unidos Mexicanos", or United Mexican States. Every seal of Mexico used in its history is also struck onto this obverse, arranged in a circular pattern around the current seal.
While the coin was first struck out of 1 oz. of .999 fine silver, its size options expanded rapidly. In 1991, the bullion coin was struck not only in its 1 oz. weight, but also with the additional sizes 1/2 oz., 1/4 oz., 1/10 oz. and 1/20 oz. This continued in 1996 with 2 oz. and 5 oz. Silver Libertads, and finally in 2002 a 1 Kilogram version was minted. The Silver Libertad is a bullion coin with one of the most diverse ranges of size available.
