The Mexican Libertad: The Currency Solution?

The Libertad is a Mexican coin that was first issued in 1981 in .999 fine gold and then in silver in 1982. Beginning in 1991, the Libertades became the only coins in the world that were issued in the convenient sizes of 1/20, 1/10, 1/4, 1/2, and 1 ounce—again, in both gold and silver.
