The Mexican Libertad: a complete history

Struck by the oldest mint in the Americas, the Mexican Libertad is one of the most distinctive bullion coins in the world, partly for its dramatic design and partly for a quirk that sets it apart from almost every rival: it carries no stamped face value at all. Its worth is simply its metal. For collectors and investors who prize beauty and relative scarcity, the Libertad has a devoted following.

The oldest mint in the Americas

The Libertad comes from La Casa de Moneda de México, the Mexican Mint, founded in 1535 and the oldest mint in the Western Hemisphere. The gold Libertad launched first, in 1981, with the silver following in 1982. The coins were created to give investors a way into Mexican precious metals, building on the country's long silver-mining heritage. Unusually among government bullion coins, the Libertad carries no denominated face value; under Mexican law it is legal tender valued by its metal content at the current price.

Winged Victory and the Angel of Independence

The Libertad's reverse is among the most striking in bullion: the Winged Victory, the golden angel that crowns the Angel of Independence monument on Mexico City's Paseo de la Reforma, completed in 1910 for the centenary of Mexican independence. She holds a laurel wreath for victory and a broken chain for freedom, with the volcanoes Popocatépetl and Iztaccíhuatl behind her, peaks tied to an Aztec legend of two lovers turned to stone. The design descends from the celebrated 1921 Centenario gold coin. The obverse carries Mexico's coat of arms, the eagle on a cactus devouring a snake.

Two design eras

The Libertad has passed through clear design phases that collectors track closely. From the start, the angel was shown front-on; in 1996 the silver coin moved to a three-quarter, slightly tilted view of the angel, the gold having used the older front-facing angel through 1999. The obverse changed too: from 2000 the central coat of arms was surrounded by ten smaller historical versions of the emblem, a compact heraldic timeline of Mexico. These shifts divide the series into earlier single-emblem coins and later multi-emblem ones.

Purity and sizes

The early gold Libertads of 1981 to 1990 were .900 fine; in 1991 and 1992 the gold moved to .999 to match international bullion standards. The silver coins are .999 fine. The silver Libertad is famous for offering the widest range of sizes of any silver bullion programme, from a twentieth-ounce up through the one-ounce to 2 oz, 5 oz and even one-kilogram coins. The one-ounce silver coin is 40 mm across; the one-ounce gold coin is smaller at 34.5 mm, reflecting gold's greater density.

Collecting and storing Libertads

The Libertad's appeal rests on its beauty, its relatively low and unpredictable mintages, and that distinctive lack of a face value. Compared with the tens of millions of American Silver Eagles struck in a typical year, Libertad mintages are modest, which gives many dates a genuine scarcity premium. For storage, the proof and proof-like finishes the Mexican Mint is known for reward careful protection in a capsule. Note the one-ounce silver coin's 40 mm diameter and the gold coin's distinct 34.5 mm size when matching a holder.
