Mexico 50 Peso Gold Coin

What is the Mexico 50 Peso Gold Coin?

The Mexico 50 Peso Gold Coin, also known as “The Centenario,” is a gold bullion coin, first minted in 1921. Known for its large size, the coin was minted from 1921 to 1931 and 1944 to 1947. In 1949 the coin was minted again. Back in 1921, its original purpose was to commemorate the 100th anniversary of Mexico’s independence from Spain – it wasn’t intended to be currency. 

Interestingly, the 50 Peso face value attached to the coin isn’t related to it’s gold value. The Centenario is 90% gold and 10% copper, and is composed of 37.5 grams, or 1.2057 troy ounces, of actual gold. It measures at 37mm in diameter and weighs 41.67 grams.

The design of the Mexico 50 Peso Gold Coin

The coin was designed by Emilio del Moral. On the obverse you’ll see the famed image, Winged Victory, otherwise known as “The Angel of Independence ” or El Ángel. The Angel stands with her right hand raised, inside she’s grabbing a laurel wreath; in her left hand are broken chains. This same design would later be reincorporated into gold and silver bullion coins as part of the Mexican Libertad Series. Two recognizable Mexican volcanoes appear behind the Angel: Popocatepetl and Iztaccíhuatl. On the lower left of the coin is a date: 1821, which commemorates Mexico’s independence from Spain. On the right side, the date stamped represents the year the coin was minted. 

A special minting of the coin occured in 1943. That year they left out the “50 Pesos” and put in “37.5 Gr Oro Puro” markings; though, the diameter remained 37mm. 

Another interesting occured between 1949 and 1972. During those years, most of the coins minted were labeled with the year “1947”. 

On the coin’s reverse, the Mexican coat of arms is featured. The design incorporates a Golden eagle with a rattlesnake in its beak; the bird is perched upon a cactus. Perhaps one of the coin’s more striking features is the phrase “INDEPENDENCIA Y LIBERTAD,” or Independence And Liberty, inscribed around its outer rim.
