The Mexican 50 Pesos Centenario is 20% larger than a standard 1 oz gold coin and typically trades at lower premiums than American Eagles or Krugerrands—making it one of the best gold coins to buy for value-focused investors.
Introduction: Why Smart Investors Are Buying Mexican Gold Pesos
You’re looking at gold coins for your portfolio. American Eagles catch your eye, but the premiums sting—8-12% over spot. Krugerrands aren’t much better. Then you discover a coin that’s been hiding in plain sight: the Mexican 50 Pesos Centenario.
This massive gold coin contains over 1.2 troy ounces of gold, typically trades at just 3-5% over spot price, and has a century of history behind it. Yet most American investors have never heard of it.
That’s changing. Demand for Mexican 50 Pesos gold coins has surged to its highest level in 13 years. Investors who once overlooked these coins for their unconventional size now recognize what Mexican investors have known for generations: the Centenario offers exceptional value.
This guide covers everything you need to know—from the coin’s fascinating history and exact specifications to authentication methods and where to buy Mexican gold pesos with cryptocurrency. Whether you’re a seasoned collector or new to buying gold with Bitcoin, the Centenario deserves your attention.
What Is the Mexican 50 Pesos Gold Coin?
The Mexican 50 Pesos gold coin, known as the Centenario (Spanish for “centenary” or “hundredth”), commemorates one of Latin America’s most significant historical milestones: Mexico’s 100th anniversary of independence from Spanish colonial rule.
First minted in 1921, this coin wasn’t designed for everyday transactions. Its substantial gold content—over an ounce of pure gold—made it too valuable for circulation. Instead, it served as both a commemorative piece and a store of wealth, embodying Mexico’s pride in its hard-won independence and its abundant mineral resources.
Why “Centenario”?
The name directly references the centennial celebration. The year 1821, prominently displayed on the coin’s obverse, marks when Mexico officially declared independence after an 11-year struggle against Spanish rule. By creating this magnificent gold coin in 1921, Mexico celebrated a century of sovereignty with a piece worthy of the occasion.
Historical context matters:
During the early 20th century, Mexico ranked among the world’s largest gold producers. The government used gold coin production to control currency supply and demonstrate economic strength. The 50 Pesos became the flagship of Mexican gold coinage—larger and more valuable than any comparable coin of its era.
Until the South African Krugerrand arrived in 1967, the Mexican 50 Pesos held the distinction of being the largest gold bullion coin readily available to investors worldwide.
The History Behind the Centenario Gold Coin
Understanding the Centenario’s history explains why this coin commands such respect among collectors and investors alike.
Birth of a National Symbol (1921)
The Centenario emerged from the aftermath of the Mexican Revolution (1910-1920), a decade of devastating civil war that reshaped the nation. As Mexico rebuilt, it sought symbols of unity and strength. The 50 Pesos gold coin became one such symbol—a tangible representation of Mexican resilience and abundant natural wealth.
Designer Emilio del Moral created a coin that drew upon Mexico’s most powerful national imagery. The result was a masterpiece that remains instantly recognizable over a century later.
Production Timeline
Original Minting (1921-1931): The first series established the Centenario as a premium gold coin. Production volumes varied by year, with some dates becoming particularly scarce and valuable to collectors.
Wartime Hiatus (1931-1942): Global economic instability and the Great Depression halted production.
Revival Period (1943-1947): Rising demand for gold during World War II prompted the Mexico City Mint to resume production. The 1943 issue is notable for occasionally omitting the “50 Pesos” denomination—a quirk that makes these coins collectible oddities.
Restrike Era (1949-1972): Here’s where things get interesting. After official production ended in 1947, the Mexican Mint produced nearly 4 million “restrikes”—coins bearing the 1947 date but manufactured years later. These restrikes contain identical gold content and trade at the same value as originals.
The restrike practice continued through 1972. Some additional coins were reportedly minted during the 2008-2009 financial crisis to meet surging gold demand.
1947 Date: The Mystery Explained
If you purchase a Mexican 50 Pesos today, it will almost certainly display the year 1947. This isn’t deception—it’s standard practice. Most circulating Centenarios are restrikes bearing this date regardless of when they were actually produced.
For investors focused on gold content rather than numismatic value, this distinction doesn’t matter. Restrikes and originals contain the same amount of gold. Collectors, however, may pay significant premiums for genuine 1921 or 1931 coins with their original mint dates.
Mexican 50 Pesos Gold Coin Design: Art Meets History
The Centenario’s design tells the story of Mexican independence through powerful symbolism. Few coins anywhere in the world match its visual impact.
Obverse: Winged Victory (El Ángel de la Independencia)
The coin’s face features Winged Victory, modeled after Mexico City’s famous Angel of Independence monument. This statue, inaugurated in 1910 to celebrate the centennial of independence, stands on the Paseo de la Reforma and remains one of Mexico’s most photographed landmarks.
On the coin, Winged Victory stands with:
- Right hand raised: Holding a laurel wreath, symbolizing victory
- Left hand extended: Grasping broken chains, representing freedom from Spanish rule
Rising behind her are two volcanic peaks—Popocatépetl and Iztaccíhuatl—legendary mountains steeped in Aztec mythology about tragic lovers transformed into eternal monuments.
Key inscriptions:
- “1821” (lower left): Year of Mexican independence
- Year of mintage (lower right): Usually 1947 for circulating coins
- “37.5 Gr. ORO PURO”: Confirms pure gold content in grams
This design later inspired Mexico’s modern Libertad series of gold and silver bullion coins—a testament to its enduring appeal.
Reverse: Mexican Coat of Arms
The reverse displays Mexico’s national emblem: a golden eagle perched on a prickly pear cactus, devouring a rattlesnake. This image derives from Aztec legend about the founding of Tenochtitlan (present-day Mexico City).
The inscription around the rim reads: “INDEPENDENCIA Y LIBERTAD” (Independence and Liberty)
Below the eagle appears “LEY 0.900″—confirming the coin’s 90% gold purity.
Edge Inscription
The coin’s edge carries the phrase “INDEPENDENCIA Y LIBERTAD” in raised capital letters—adding another layer of security against counterfeiting while reinforcing the patriotic message.
Visual Impact
The Centenario’s 37mm diameter—20% larger than a standard 1 oz gold coin—gives it an undeniable presence. The copper alloy creates a distinctive warm, orange-gold hue that distinguishes it from purer 24-karat coins. Many collectors find this color more visually appealing than the paler yellow of .9999 fine gold.
Mexican 50 Pesos Specifications: Complete Technical Guide
Precise specifications matter for authentication and investment purposes. Here’s the complete technical profile:
Gold Content and Composition
| Measurement | Value |
|---|---|
| Pure Gold Content | 37.5 grams (1.2057 troy ounces) |
| Total Weight | 41.67 grams (1.339 troy ounces) |
| Gold Purity | .900 fine (90% gold) |
| Alloy Composition | 10% copper |
| Karat Rating | 21.6 karat |
The copper content isn’t a flaw—it’s a feature. Adding copper creates a harder, more durable coin that resists scratching and maintains its appearance through decades of handling. This is the same approach used for American Gold Eagles and Krugerrands.
Physical Dimensions
| Dimension | Measurement |
|---|---|
| Diameter | 37 mm |
| Thickness | 2.69 mm |
| Edge | Lettered (“INDEPENDENCIA Y LIBERTAD”) |
Comparison to Other Gold Coins
| Coin | Gold Content | Total Weight | Diameter | Purity |
|---|---|---|---|---|
| Mexican 50 Pesos | 1.2057 oz | 41.67g | 37mm | 90% |
| American Gold Eagle (1 oz) | 1.000 oz | 33.93g | 32.7mm | 91.67% |
| South African Krugerrand | 1.000 oz | 33.93g | 32.77mm | 91.67% |
| Canadian Maple Leaf | 1.000 oz | 31.10g | 30mm | 99.99% |
| Austrian 100 Corona | 0.9802 oz | 33.88g | 37mm | 90% |
Key insight: The Centenario delivers 20% more gold than a standard 1 oz coin. For investors buying in quantity, this translates to meaningful savings on per-ounce premiums.
How Much Is a Mexican 50 Pesos Gold Coin Worth?
The Centenario’s value depends on gold spot prices, premiums, and—for certain dates—numismatic factors.
Current Market Value (2026)
Based on current gold prices, the melt value of a Mexican 50 Pesos is approximately $5,500-$5,800 USD (1.2057 oz × gold spot price). Actual purchase prices include dealer premiums.
Premium Structure
One of the Centenario’s greatest advantages is its consistently low premium over spot:
| Coin Type | Typical Premium Over Spot |
|---|---|
| Mexican 50 Pesos | 3-5% |
| American Gold Eagle | 5-8% |
| Canadian Maple Leaf | 4-7% |
| South African Krugerrand | 4-6% |
| American Buffalo | 8-12% |
Why the low premiums?
Several factors keep Centenario premiums modest:
- Less marketing and promotion than American or Canadian coins
- Abundant supply from restrike production
- Lower demand in the U.S. compared to Mexico and Latin America
- Unconventional 1.2 oz size initially deterred some investors
For value-focused buyers, these “disadvantages” are actually benefits—more gold for your dollar.
Numismatic Premiums by Date
While most 1947-dated coins (whether original or restrike) trade near melt value, certain dates command significant collector premiums:
| Year | Mintage | Premium Level |
|---|---|---|
| 1921 | 180,000 | High (first year) |
| 1922 | 463,000 | Moderate |
| 1923 | 432,000 | Moderate |
| 1924 | 439,000 | Moderate |
| 1925 | 716,000 | Low-Moderate |
| 1926 | 600,000 | Low-Moderate |
| 1927 | 606,000 | Low-Moderate |
| 1928 | 538,000 | Low-Moderate |
| 1929 | 458,000 | Moderate |
| 1930 | 372,000 | Moderate |
| 1931 | 137,000 | High (last original year) |
| 1943 | 89,000 | Moderate-High (no denomination variety) |
| 1944 | 593,000 | Low |
| 1945 | 1,012,000 | Low |
| 1946 | 1,588,000 | Low |
| 1947 (original) | 309,000 | Moderate |
| 1947 (restrikes) | ~4,000,000 | Very Low |
Investment tip: If your goal is maximum gold per dollar, purchase random-year coins or confirmed restrikes. Save the premium for rare dates only if you’re building a collection.
Why Invest in Mexican 50 Pesos Gold Coins?
The Centenario offers compelling advantages for specific investment strategies.
Advantage 1: More Gold, Lower Premiums
Simple math favors the 50 Pesos:
- Buying 1.2 oz of gold via Centenario: Spot + 3-5% premium
- Buying 1.2 oz via American Eagles: 1 oz coin + premium (5-8%) + fractional coin + premium (8-15%)
Over a significant portfolio, these savings compound substantially.
Advantage 2: Exceptional Durability
The 90% gold / 10% copper alloy creates one of the most durable gold coins available. Centenarios that have circulated for decades often show minimal wear—maintaining both appearance and resale value.
In contrast, pure .9999 gold coins (Maple Leafs, Buffalos) scratch easily and require careful handling.
Advantage 3: Historical and Numismatic Appeal
Unlike modern bullion coins that feel mass-produced, the Centenario carries genuine historical weight. First-year 1921 coins were minted just a year after Mexico’s brutal civil war ended. Holding one connects you to a pivotal moment in North American history.
This dual appeal—bullion value plus collector interest—provides downside protection that pure bullion lacks.
Advantage 4: Strong Latin American Demand
While American investors often overlook the Centenario, it remains extremely popular in Mexico and throughout Latin America. This regional demand creates stable liquidity and supports prices during market downturns.
Advantage 5: Proven Crisis Performance
During the 2008-2009 financial crisis, demand for Centenarios surged so dramatically that the Mexican Mint reportedly struck additional coins to meet it. When investors flee to physical gold, the 50 Pesos performs.
When the Centenario Might Not Fit
Consider alternatives if:
- You prefer the smaller size and standardization of 1 oz coins
- You want the highest purity (.9999 fine gold)
- You need coins eligible for certain IRAs (check with your custodian)
- You’re primarily building a collection of specific mint years
How to Authenticate a Mexican 50 Pesos Gold Coin
The Centenario’s popularity makes it a counterfeiting target. Here’s how to verify authenticity.
Specification Check: Weight and Dimensions
This is your first and most effective defense:
| Specification | Authentic Value | Tolerance |
|---|---|---|
| Total Weight | 41.67 grams | ±0.05g |
| Diameter | 37 mm | ±0.2mm |
| Thickness | 2.69 mm | ±0.1mm |
Equipment needed: Digital scale (0.01g precision), digital calipers
A coin that’s the correct weight but wrong dimensions (or vice versa) is almost certainly counterfeit. Matching all three measurements simultaneously is extremely difficult without real gold.
Pro tip: The Fisch detection system has caught numerous fake Centenarios that were the correct weight but slightly too large in diameter or too thick.
The Ping Test
The 90% gold / 10% copper alloy produces a distinctive, clear ring when struck—one of the most recognizable among gold coins. This makes the ping test particularly effective for Centenarios.
To perform the test:
- Balance the coin on your fingertip at its edge
- Tap gently with a pencil or plastic rod
- Listen for a clear, sustained ring (3-5 seconds)
22-karat coins like the Centenario produce a more distinctive ring than 24-karat coins. A tungsten fake produces no ring whatsoever—just a dull thud.
Learn more about testing methods in our complete gold coin authentication guide.
Visual Inspection
Examine under magnification for:
Design quality:
- Sharp, well-defined details on Winged Victory
- Clear feather definition on the eagle
- Crisp edge lettering (“INDEPENDENCIA Y LIBERTAD”)
Color consistency:
- Warm, orange-gold tone (characteristic of 90% gold alloy)
- Even color across the entire coin
- Natural luster without artificial shine
Red flags:
- Seams along the edge (indicates filled or two-piece fake)
- Bubbling or pitting on surfaces
- Letters that appear stamped rather than struck
- Unusual color variations
The Magnet Test
Gold is non-magnetic. If your coin shows any attraction to a strong neodymium magnet, it contains ferrous metals and is definitely fake.
However, passing the magnet test doesn’t confirm authenticity—sophisticated counterfeits use non-magnetic metals like tungsten or lead.
Specific Gravity Test
For ultimate verification, calculate the coin’s density:
- Weigh the coin precisely (M grams)
- Measure water displacement when submerging the coin (V milliliters)
- Calculate: Density = M ÷ V
Expected result: Approximately 17.1-17.5 g/cm³ (90% gold alloy is less dense than pure gold’s 19.3 g/cm³)
Common Centenario Counterfeits
Be especially vigilant for:
- Drilled and filled coins: Real coins with gold removed and replaced with lead. Check for filled holes near the rim.
- Gold-plated base metal: Fails weight test; may pass visual inspection
- Tungsten core fakes: Correct weight but fails ping test and dimensional checks

Mexican 50 Pesos vs. Other Gold Peso Denominations
The 50 Pesos is the flagship, but Mexico produced other gold peso denominations worth knowing:
| Denomination | Gold Content | Total Weight | Diameter | Premium Level |
|---|---|---|---|---|
| 50 Pesos | 1.2057 oz | 41.67g | 37mm | Lowest |
| 20 Pesos | 0.4823 oz | 16.67g | 27.5mm | Low-Moderate |
| 10 Pesos | 0.2411 oz | 8.33g | 22.5mm | Moderate |
| 5 Pesos | 0.1206 oz | 4.17g | 19mm | Higher |
| 2.5 Pesos | 0.0603 oz | 2.08g | 15.5mm | Higher |
| 2 Pesos | 0.0482 oz | 1.67g | 13mm | Highest |
Investment implications:
Smaller denominations carry progressively higher premiums per ounce of gold. The 50 Pesos offers the best value for investors; smaller sizes suit collectors or those wanting fractional gold for potential barter scenarios.
Frequently Asked Questions
Is the Mexican 50 Pesos a good investment?
For value-focused gold investors, the Centenario is excellent. Its consistently low premiums (3-5% over spot) mean more gold per dollar compared to popular alternatives like American Eagles. The coin’s durability, historical significance, and strong Latin American demand provide additional appeal. However, if you need coins for a specific IRA or prefer standardized 1 oz sizes, alternatives may fit better.
Why do most Mexican 50 Pesos say 1947?
The Mexican Mint produced nearly 4 million “restrikes” between 1949 and 1972, all bearing the 1947 date—the last year of official production. This practice was common for bullion coins and doesn’t affect gold content. Restrikes trade at the same value as originals dated 1947.
Are Mexican gold coins IRA eligible?
Some gold IRAs accept Mexican gold pesos, but eligibility varies by custodian. The 90% purity technically falls below the standard .995 fineness requirement for IRA gold. Always verify with your IRA administrator before purchasing.
How can I tell if my Mexican 50 Pesos is real?
Verify weight (41.67g), diameter (37mm), and thickness (2.69mm) using precision instruments. Perform the ping test—genuine Centenarios produce a distinctive, sustained ring. Check for proper coloration (warm orange-gold) and sharp design details. For valuable coins, consider professional authentication through PCGS or NGC.
What’s the difference between original Centenarios and restrikes?
Original coins were minted from 1921-1947 and bear their actual year of production. Restrikes (1949-1972) all carry the 1947 date. Gold content is identical. Originals from 1921 or 1931 carry collector premiums; restrikes trade at bullion value. Visual differences can include slightly different patina—restrikes sometimes have a more matte, copper-toned finish compared to original mint luster.
Where can I buy Mexican 50 Pesos gold coins with Bitcoin?
BitGolder accepts Bitcoin, Ethereum, and other cryptocurrencies for gold purchases, including Mexican gold coins. Anonymous purchases up to $20,000 are available, combining cryptocurrency privacy with physical gold ownership.
Key Takeaways
The Mexican 50 Pesos Gold Coin offers exceptional value for investors seeking maximum gold content at minimum premiums, backed by a century of history and enduring collector appeal.
- Best value in gold bullion: 1.2057 oz of gold at premiums of just 3-5% over spot—significantly lower than American Eagles or Krugerrands
- Exceptional durability: 90% gold / 10% copper alloy resists scratching and maintains appearance, even after decades of handling
- Rich historical significance: First minted in 1921 to celebrate Mexican independence, with design elements that influenced modern Libertad coins

For investors prioritizing gold content over brand recognition, the Mexican 50 Pesos Centenario remains one of the most intelligent choices in the precious metals market.
Conclusion: Is the Mexican 50 Pesos Right for You?
The Centenario occupies a unique position in the gold coin market. It offers more gold than a standard 1 oz coin at lower premiums than most alternatives—a combination that appeals powerfully to value-conscious investors.
This coin rewards those willing to look beyond the American-centric bullion market. While your neighbors stack Eagles and Buffalos, you’ll hold 20% more gold per coin at a fraction of the premium.
