In 2006 the Mexican Mint released Libertad Angel Silver Proof Coin struck in solid fine .999 Silver weighing two ounces of pure Silver struck to a proof finish.
The reverse is the stunning Independence Angel the symbol of Mexico City and stands in front of the Iztacc'huatl and Popocat'ptl volcanoes.
The obverse features an eagle battling a snake (Mexico's national coat of arms), which is surrounded by a wreath and the words "ESTADOS UNIDOS MEXICANOS". Encircling the center are ten eagle designs that have been used as National Emblems through the centuries, including one depicted in the 16th century Mendocino Codex fineness and amount of silver, the date, and the name of the issuing country ('MEXICO').
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
