1 Centavo 1958 Copper Coin (Mexico): What It's Worth

If you inherited or found a Mexican 1 centavo 1958 copper coin, here is the honest answer: in circulated condition it's worth a few cents, not a fortune. A crisp uncirculated example can bring a couple of dollars, and only top-graded pieces or genuine mint errors climb higher. This is a common coin, and no myth about "old Mexican coins worth millions" changes that.

Quick answer: is the 1958 centavo worth money?

The 1 centavo (one cent) dated 1958 is a small copper coin from the Casa de Moneda de México, the Mexican Mint, and one of the most produced denominations of its era. Millions survive. For a US reader in 2026, that means:

• Circulated (worn), the everyday find: roughly 10 to 50 US cents to a collector.
• Uncirculated, sharp detail and original color: commonly 1 to 3 dollars.
• Top certified grade or verified mint error: occasionally more, but you need proof.

Most coins that come out of a jar or an inherited box fall in the first bracket. That is the reality, not a disappointment. Value here comes from condition, not age.

What this coin actually is

A "centavo" is one-hundredth of a Mexican peso, the same idea as a US cent to the dollar. The 1958 issue belongs to Mexico's modern pre-1992 series and was struck in copper for daily circulation.

Specifications (keep these for authentication):

• Denomination: 1 centavo
• Year: 1958
• Metal: copper
• Weight: 1.96 grams
• Diameter: 16 millimeters
• Edge: plain (smooth)
• Mint mark: "Mo" (Casa de Moneda de México)

Obverse (front): the Mexican national coat of arms, the eagle on a cactus, with the legend "ESTADOS UNIDOS MEXICANOS" (United Mexican States, the country's official name).

Reverse (back): the face value shown large, the year 1958, and the "Mo" mint mark.

Value by condition

Since this is a common date, grade drives everything. A coin that has been in circulation for decades shows flat detail and dark, spotty toning. An uncirculated coin still has full design sharpness and original mint luster.

Copper is a base metal with almost no melt value at this weight, so there is no bullion floor propping up the price the way there is with silver coins. If you want to understand where your coin sits, check the coin grading guide before you assign it a value.

The part people get wrong

The common belief is that any old coin from the 1950s is rare and valuable. It isn't. The 1958 centavo was minted in large numbers and is easy to find, so scarcity does not apply. What can raise the price is a genuine, verifiable mint error: an off-center strike, a die rotation, a doubled die, or a documented variety.

Be careful here. Most "errors" posted online are actually post-mint damage: corrosion, acid stains, or hits from being in a jar of coins for fifty years. That is not a factory error and it lowers value, it does not raise it. A real error needs to be confirmed by someone who knows what they are looking at.

If your coin is a bullion piece like an Onza Libertad or a gold Centenario, the rules are completely different because those trade on silver and gold content. This little copper centavo does not.

How to tell if yours is genuine

Counterfeits of a coin worth a dollar are rare, but altered or damaged coins are common. To verify authenticity:

1. Weigh it on a jewelry scale. It should read close to 1.96 grams.
2. Measure the diameter with calipers. It should be 16 millimeters.
3. Check the relief and color. Genuine strikes have crisp raised detail and even copper tone. Fakes tend to look flat or have uneven color.

If the weight or diameter is off, the piece is suspect.

Where to sell it

Don't dump it on social media at the first offer. For a fair price:

• A verified coin shop from the Pesoteca shop directory can grade and value it on the spot.
• The Pesoteca buy-and-sell forum connects you directly with collectors.

Photograph the obverse, reverse, and edge in good light, and compare against the value ranges above before you accept any offer. Realistically, a single common centavo is worth more as part of a full set or a lot than sold alone.

Think you might have a real mint error or an unusually sharp example? Post clear photos in the Pesoteca forum and let the community weigh in before you sell.

Mexican circulating centavo coins during the second half of the 20th century were struck in alloys that changed with metal costs: copper, bronze, and brass in the low denominations (1¢, 5¢, 20¢); cupronickel for the intermediate denominations (25¢, 50¢, late 10¢); and .720 silver for some 25¢ and 50¢ pieces in the 1950s. Each alloy change generated a distinct variety of the same face value. 1958 corresponds to the period in which this variety was in circulation, before the transition to Nuevos Pesos in 1992. The Mexican Mint kept the basic design of the National Coat of Arms on the obverse and the numeric value on the reverse throughout this era.
