A commemorative and historical coin

The Mexican 50 pesos coin was designed to celebrate a crucial moment in Mexican history: the centenary of independence achieved in 1821 after a decade of struggle against Spanish domination. It is minted by the Casa de Moneda de México, the oldest mint in the Americas.

The coin was produced between 1921 and 1947, before being mass-restruck from 1949 to meet the growing demand from international markets. These restrikes, although bearing the date 1947, continued until 1972, with some strikes even made in the 1990s.

At first, this coin was nicknamed "the mini ingot." Highly prized in France, it long replaced the Krugerrand, which was unavailable in the country at that time.

Technical characteristics and composition

The 50 pesos coin stands out for its generous dimensions.

Total weight: 41.67 grams

Weight in pure gold: 37.5 grams (or 1.2057 troy ounces)

Diameter: 37 mm

Purity: 90% gold alloyed with 10% copper

With these specifications, it is one of the largest classic gold investment coins, surpassing in size and weight the British sovereigns or classic one-ounce coins. Its gold-copper alloy makes it more resistant to shocks/scratches than pure gold coins (such as Maple Leaf, Philharmonique…), which makes it easier to maintain in excellent condition.

A symbolic and impressive design

The design of the 50 pesos coin honors Mexican history and culture.



  • Obverse: The national emblem of Mexico is depicted, featuring a royal eagle perched on a cactus holding a serpent in its beak. The inscription “Estados Unidos Mexicanos” (translation: United Mexican States) surrounds this image.

  • Reverse: It features the majestic figure of the Winged Victory, known as "El Ángel de la Independencia" (translation: the Angel of Independence), holding a laurel wreath in her right hand and broken chains in her left hand. In the background, the Popocatépetl and Iztaccíhuatl volcanoes, two mythical mountains of the country, can be seen. The independence date "1821" and the minting year "1947" are engraved on either side of the figure.



On the edge, the following inscription is found: "INDEPENDENCIA Y LIBERTAD" (translation: independence and freedom).

A coin valued by collectors and investors

The 50 pesos coin has always established itself as a safe haven. For example, during World War II, when uncertainty reigned over the economy, many investors and individuals sought ways to preserve their wealth. The 50 pesos coin quickly became known for its impressive weight. Some travelers and expatriates even sewed these coins into their clothing to bypass monetary restrictions and discreetly carry their fortune. Around 1970, with the rise of inflation and the skyrocketing price of gold, the 50 pesos coin saw an exceptional resurgence in interest. So much so that some examples, even though restruck after 1947, sold well above their intrinsic value, transforming this "mini ingot" into a true legend.

Even today, the 50 pesos is considered a timeless investment. It is also worth noting that this coin is often available at relatively low premiums compared to the price of gold.
