The Mexican Libertad Gold Bullion Coin was first issued in 1981 and paved the way for its sister series, the Silver Libertad, which debuted the very next year. Each gold coin contains the stated amount of 99.9% pure gold making them one of the purest bullion strikes produced in the world.
Both Libertad series are products of the Casa de Moneda de México (Mexican Mint) which has the distinction of being the oldest minting facility in the Americas. It was initially established on the order of the Spanish Crown by Viceroy Antonio de Mendoza in 1535.
The Mexican Libertad Gold Bullion Coin was initially struck in only the one ounce size, but it became the first world bullion coin to be routinely struck in fractional sizes in 1991. At that time, the Mexican Mint started also producing 1/2 ounce, 1/4 ounce, 1/10 ounce and 1/20 ounce sized Gold Libertads. All of them are struck in relatively low mintages which usually results in an early sell-out from suppliers.
Imagery on the Gold Libertads is almost identical to that of the Silver Libertads, with the exception of the gold indicating inscriptions. As such, the obverse of the coin shows a winged Victoria standing atop the Mexican Independence Victory Column. The column is located in Mexico City at the Paseo de la Reforma in downtown. It was cast in bronze (but covered in gold) to celebrate the centennial of the Mexican War for Independence. Victoria is the Roman goddess of victory and is shown with a wreath in her right hand symbolizing victory and a broken chain in her left symbolizing freedom. Included as well are the inscriptions indicating the size and purity of the strike.
The reverse includes the Coat of Arms for Mexico which depicts and eagle battling a snake an is surrounded by the inscription of "ESTADOS UNIDOS MEXICANOS". Placed around that design are additional eagle designs which have been used as the emblem of Mexico over the years.
