Mexico’s Gold Centenario: The Historic 50 Peso Mexican Gold Coin

In Spanish, moneda de oros means gold coins. In reference to Mexican gold pieces, the Spanish wording arguably carries a more formal, elegant sound—and with good reason. The Mexican 50 peso gold coin was the Mexican Mint’s purest gold coin and ranked among the purest gold coins produced worldwide.

The gold 50 Peso, better known as the Centenario, was not made for circulation. It was first struck in 1921 to mark Mexico’s 100 years of independence. It remained the purest gold coin weighing one ounce or more until the gold Krugerrand appeared in 1967.

Whether someone likes the design or not, the gold 50 peso has a deep history in the coin and bullion trade. That history made it one of the more interesting foreign gold coins Atlanta Gold & Coin handled, for several different reasons.

At the time of publication, demand and popularity for this coin had recently returned noticeably.

Somewhat ironically, this coin once traded considerably below gold’s spot price and received little attention from most investors. Its unusual size, or gold weight, put off some people because it is 1.2 ounces rather than the more familiar one-ounce coin.

The coin’s patina was also viewed as a possible obstacle to broader demand. Yet the earlier assumptions investors held about it no longer seemed to apply at the time this article was published.

When this article was originally published, many investors were only beginning to encounter the 50 peso gold coin. Atlanta Gold & Coin considered it useful to spotlight the piece and cover facts that readers might not already have known.

In short, this is not an ordinary modern 1 oz gold bullion coin, particularly when its history is considered.

Production Years

At the time of publication, most Gold Centenarios, or 50 peso gold coins, traded in the industry carried the date 1947. It may appear to be an arbitrary date. However, it was the last official production year for the 50 peso gold coin, although many later restrikes retained that same date. Most coins dated 1947 were technically restrikes made from 1949 through 1972, without reducing their demand or popularity.

Put another way, these pieces traded much like an original 1947-struck coin. As a comparison, 309,000 coins were first produced in 1947, while almost 4 million were restruck between 1949 and 1972.

Although 1947-dated Mexican gold Centenarios are the most common gold coin, they were not the earliest issue.

Readers with some Spanish familiarity may recognize that the English meaning of “Centenario” is “centenary”, or one hundred. Looking back to Mexico’s independence in 1821 confirms that the original Centenario was first struck in 1921.

That year, the Mexican Mint made only 180,000 50 peso gold coins, commemorating the country’s 100-year independence from Spain.

Original 50 peso gold coins were struck over sixteen years, from 1921 through 1947, excluding restrike production from 1949 – 1972. In most years, mintages of the 50 peso gold coins reached 500,000 or more, and some climbed as high as 1.588 million. A few low-mintage dates, however, sold for a modest premium.

The smallest mintage occurred in 1943 with a production of only 89,000 coins.

The next-lowest mintage was 137,000 in 1931. It was followed by the first year, 1921, which had a mintage of 180,000 coins.

Size

The 50 peso gold coin’s dimensions may be its most notable feature. It weighs 41.6 grams and contains 90% pure gold. That works out to 37.5 grams of pure gold, or an actual gold weight (AGW) of 1.2057 troy ounces.

There is no need to estimate the gram weight of the 50 peso Mexican gold coin. The weight was struck directly onto the coin’s obverse, where it reads: “37.5 Gr Oro Puro.”

For readers who may not know the abbreviation, AGW identifies how many ounces of pure gold a coin contains. To calculate its AGW, divide the grams of pure gold by 31.1. 31.1 serves as the divisor because it represents the number of grams contained in one troy ounce of gold.

Before publication, the unusual dimensions and weight may have discouraged some prospective buyers and investors. At the time this article was written, though, that no longer appeared to be the situation.

The original article reported that the coin’s standing in Mexico was unaffected. Atlanta Gold & Coin occasionally met customers who had lived in Mexico and described the coin as tremendously popular there.

Purity

As noted earlier, the 50 peso gold coin has a purity of 90%, comparable to many foreign and old-world gold coins. It is also the purity used for pre-1933 U.S. gold coins. Although calculating AGW, or pure-gold ounces, can be less straightforward for such coins, they generally display little visible wear.

These coins tend to remain attractive and retain their original look partly because of their metal composition. People familiar with gold generally know that, as gold purity rises, the metal becomes softer.

At publication, For instance, 24k gold coins are quite soft, making them vulnerable to scratches, contact marks, and handling marks.

At publication, That is unlike a coin made from 90% gold. For the 50 Mexican peso, copper is included as a base alloy to improve durability and resistance to contact marks. This resilience added to the coin’s appeal, since Atlanta Gold & Coin rarely encountered an example of poor quality.

This is not strictly a purity matter: restrikes have the same metal composition as original 50 peso gold coins, but their visual appearance often differs.

Restrikes usually show more coppery or rose-gold color and often lack the original mint luster seen on earlier-dated coins. Instead, their surface is typically more matte in appearance, much like the finish of a burnished gold coin.

Demand at Publication

As discussed earlier in the original article, demand for particular products rises and falls over time. At the time of publication, Atlanta Gold & Coin reported its strongest demand ever for 50 peso gold coins over the preceding 13 years.

The original article did not identify exactly what was causing demand at publication, but it offered several possible explanations…

1. At the time of publication, demand for most gold and silver coins and bullion stood at a multiyear high. U.S. gold and silver coins were the most popular items, driving premiums well above historic averages. Because those coins were expensive then, the article suggested that some investors may have been seeking alternatives, helping explain added interest in 50 peso gold coins.
2. The original article generally avoided politics and government policy, but observed an influx of people crossing the border during the preceding couple of years. It noted that not everyone immigrating was destitute. Like many Americans, it suggested, people arriving from south of the border were concerned about inflation and sought a safe-haven investment option to preserve wealth. At the time of publication, Mexico’s inflation rate was 8.7%, described as comparable with the inflation rate in the United States.
3. The original article said that while many people from Mexico crossed the border seeking a more prosperous life, some Americans were also leaving the United States for Mexico for political reasons and a lower cost of living. At publication, Atlanta Gold & Coin regularly heard of expat communities in Mexico. It suggested that people planning a move, or already relocated, might have been purchasing 50 peso gold coins because they expected them to be more recognizable and liquid than modern bullion gold coins if they later chose to sell.
4. Another possible explanation for the increased demand was simply the coin’s beauty and visual appeal. When the article was published, many investors exploring gold alternatives beyond mainstream U.S. gold and silver coins were considering the 50 peso for the first time. The article described them as among the market’s most attractive gold coins. Emilio del Moral designed the coins, which show Winged Victory, representing the Angel of Independence. She carries a laurel crown in her right hand as a symbol of victory. Her left hand holds broken chains, representing freedom. The design also refers to the famous statue known affectionately as El Ángel, erected by Mexico’s people in 1910 in central Mexico City to commemorate 100 years since the start of their war for independence from Spain. The obverse, or back, presents the Mexican Coat of Arms and an eagle on a cactus consuming a serpent.

Summary

The 50 peso Mexican gold coin, also called the Centenario, combines visual appeal with an interesting history and several practical strengths. Earlier issues were struck in smaller quantities and generally carried higher premiums. At the time of publication, however, later 50 peso pieces, including restrikes, were also sought after and were reported to be bringing their highest premiums in years.

The coin’s substantial size and resilient construction were presented as notable advantages. At approximately 20% larger than many modern bullion coins, these pieces have a presence that distinguishes them. Their metal makeup also helps limit pronounced wear as time passes, including when a coin has not been handled with particular care.

The article also outlined possible reasons the 50 peso appeared to have greater demand than it had previously. That assessment was expressly only an informed estimate, since Atlanta Gold & Coin had not surveyed every customer and was working from limited information available at publication.
