Mexican Peso Gold Centenario Bullion Coins

The Mexican Peso Gold Coins were first minted at the Mexico City Mint in 1921. This Mexican 50 Peso gold bullion coin is more commonly known as the “Centenario” as it commemorates the victory of independence from Spain a hundred years prior in 1821.  This centennial coin was designed by Emilio del Moral. The Gold Centenario Mexican gold bullion coin contains 1.2 ounces of pure gold.

Mexican National Coat of Arms is on the reverse, an eagle perched on a cactus clutching a serpent in its beak. It is encircled by the words “Estados Unidos Mexicanos” (United Mexican States) at the top with a laurel and an oak branch at the bottom plus 68 dentils around the rim.

In 1910 a statue of El Ángel de la Independencia was erected in Mexico City at the top of the independence column. The “Angel of Independence” commonly called the Winged Victory holds in one hand a Laurel Wreath symbolizing victory and in the other a broken chain suggesting freedom.

The Design Of The Gold Peso. The obverse features the “Winged Victory” as its theme along with its celebration of Mexico’s Independence from Spain. On the left side of the Winged Victory is the nominal face value, 50 pesos and on the right side “37.5 Gr Oro Pur” is inscribed meaning 37.5 grams of pure gold. This coin bears two dates, 1821 on the left marking the year of Mexico’s Independence and on the other side the date of the coin. Along the top of the rim are forty dentils. In the background are two legendary volcanoes, the Popocatepetl and Iztaccihuatl.

After the centennial coin was minted in 1921 the coin was produced annually until 1931 when there was a 10 year lapse. This was probably due to the effects of the “Great Depression”. When the mint recommenced production in 1943 they decided to make a small change to the coin. They removed the 50 Peso face value and replaced the inscription with a duplicate of the weight and pure gold statement. The following year they put the 50 Peso face value back on the coin where it has remained since.

The Mexican Mint from 1947 onwards decided to continue production every year using the same dies, therefore the date would remain as 1947 on all future coins made with the original dies. This form of minting is known as “Coin Re-strike”. All Mexican 50 Peso gold coins would continue to have the dual dates of 1821 – 1947 and would be minted for investment purposes.

In 1996 the original die was re-tooled producing approximately only 300 coins in that year. They are considered to be semi-proofs with a very high luster finish and because of the very small mintage they are also very rare. Apparently the retooling of the original die was not a success as in 2004 a new die was created which produced a new coin with a matte finish.

The Mexican 50 Peso gold coin is 21.6 karats and is made up of 90% pure gold and 10% copper. This alloy mix gives the coin greater durability and prevents scratching and marking.

The Mexican Peso is 20% bigger than most other bullion gold coins like the American Buffalo, the Eagle and the South African Krugerrand bullion coins. It has a diameter of 37mm and a thickness of 2.5mm with a total gross weight of 41.667 grams (1.46976 oz) of gold alloy which contains 37.5 grams (1.2057 oz) of pure gold.

If you compare the gold content with the American Buffalo gold bullion coins or the Gold Eagle gold bullion coins which only have 31.1 grams (1 troy oz) you will see that you are getting a lot more gold for your money. 20% more gold makes the Mexican 50 Peso Centenario gold bullion coin an ideal investment especially with its lower premium.
