50 Pesos Centenario Gold Coin (1947): Value & Prices

If you inherited a 1947 Mexican 50 Pesos gold coin, here's the honest answer: it's worth real money, but not because it's rare. This is a gold bullion coin. In 2026, its value tracks the gold price, and the piece contains 1.2057 troy ounces of pure gold, worth over 3,000 USD in metal alone at recent spot prices.

The coin you have is called the Centenario (Spanish for "centennial"). Mexico first struck it in 1921 to mark 100 years since the country won independence from Spain, and the mint kept producing it for decades afterward, including your 1947 date. Collectors and investors around the world know it as one of the classic gold coins of the Americas.

What it's worth right now

The Centenario is a gold coin first, a collectible second. That means it has a hard floor: its melt value. It will never sell for less than the gold inside it, and for the common 1947 date, that melt value is essentially the whole story.

Here is what drives the number:

• Gold content: 41.6667 grams gross weight, struck in .900 fine gold. That works out to 37.5 grams of pure gold, or 1.2057 troy ounces.
• Spot price: whatever gold trades at on the day you sell. Multiply spot per ounce by 1.2057 to get the melt value.
• Condition: for a standard 1947, condition adds only a small premium over melt unless the coin is exceptional.
• Original Banxico packaging: if it came in its original sealed blister from the Bank of Mexico, that can add a modest premium.

Value by condition (1947 date)

Condition	What it means	Value over melt
Circulated / handled	Wear, scratches, cleaned	Melt value (metal only)
Uncirculated (BU)	No wear, some bag marks	Melt plus small premium
Choice/Gem (MS64+)	Sharp, clean surfaces	Melt plus a stronger premium

Because this coin is bought and sold mainly for its gold, the practical answer for almost every 1947 Centenario is: it's worth its melt value, which recently runs above 3,000 USD. Check the live gold price the day you plan to sell.

Is the 1947 date rare?

No, and this is where a lot of sellers get misled. The 1947 Centenario is a common date. Mexico also produced official restrikes of the Centenario dated 1947 for decades, which is why so many exist and why the date alone does not make yours special. A worn 1947 and a pristine 1947 both sell close to their gold weight.

That's actually good news if you're selling: you know what it's worth, and any buyer offering far below melt is trying to take advantage of you.

Earlier or lower-mintage Centenario dates in high grade can carry a collector premium above gold, but the 1947 is not one of the scarce dates.

What your coin looks like

Use these details to confirm you have a genuine Centenario before you sell.

• Obverse (front): The Mexican national coat of arms, an eagle on a cactus, with the inscription "ESTADOS UNIDOS MEXICANOS" (United Mexican States).
• Reverse (back): The Winged Victory, Mexico's Angel of Independence, standing above the two volcanoes Popocatépetl and Iztaccíhuatl. It reads "50 PESOS," carries the commemorative dates "1821-1921," and shows the strike year "1947."
• Edge: Reeded (grooved).

How to tell if yours is genuine

Gold coins get counterfeited because the metal is valuable, so verify before you buy or sell.

1. Weigh it. A real Centenario weighs 41.6667 grams. A jewelry scale that reads to 0.01 g will catch most fakes instantly.
2. Measure the diameter. It should be 37 mm. Use calipers.
3. Inspect the strike. Genuine pieces have crisp, deep relief and even color. Flat details, blurry lettering, or an off shade of gold are red flags.
4. Be suspicious of a bargain. Any offer well below the melt value of the gold is almost always a fake or a scam.

For a coin this valuable, having it authenticated by a professional grading service (NGC or PCGS) removes all doubt and can help you sell for a fair price.

Where to sell it safely

You have a piece worth thousands of dollars in gold, so protect yourself:

• A verified coin dealer who will weigh and appraise it in front of you and pay close to melt for the metal. Check our dealer directory to find one.
• The Pesoteca buy-and-sell forum, where collectors trade directly.
• Photograph the obverse, reverse, and edge before you talk to any buyer.
• Never ship a gold coin before verifying the buyer, and never accept an offer under melt.

Watch the live gold price the week you sell, since your payout moves with it. Compare that against our coin grading guide and the rest of the Centenario 50 Pesos gold series to confirm what you have.

This piece is a 50-peso gold Centenario struck in 1947, a commemorative type for the centennial of the consummation of Independence (September 27, 1821), first issued in 1921 under the government of Álvaro Obregón.

In 1947 Miguel Alemán Valdés (1946-1952) was in power, the first post-revolutionary civilian president. His term was characterized by industrialization and the drive toward the so-called Mexican miracle.

The obverse bears the Winged Victory taken from the column of the Angel of Independence (inaugurated in 1910), with Popocatépetl and Iztaccíhuatl in the background, attributed to the sculptor José Núñez Ledesma. The reverse shows the national coat of arms. Specifications: total weight 41.6666 grams, .900 fineness, pure gold content 37.5 grams (1.2057 troy ounces), diameter 37 millimeters, reeded edge. Krause reference KM#481 for the classic 1921-1947 cycle.

The year 1947 corresponds to the close of the classic cycle. Its official mintage is the highest of the KM#481 family, which makes it the most accessible classic Centenario in the Mexican numismatic market.

In the Mexican market the Centenario is bought for its gold content (1.2057 troy ounces) and for its numismatic value when the year has a short mintage. When hunting for it, compare the premium over spot at several houses and verify the weight (41.6666 grams) and diameter (37 millimeters) to rule out reproductions before accepting a con artist's markup.
