1955 Mexican 1 Centavo (Bronze): Value & Prices

If you inherited or found a 1955 Mexican 1 centavo, here is the honest answer: in circulated condition it is worth cents, not dollars. A well-preserved uncirculated example might bring a few dollars from a collector. This is a common coin, not a rarity, and no genuine 1955 centavo is worth a fortune. Below are the real numbers by condition and how to check yours.

What this coin actually is

The 1955 1 centavo is a small bronze coin from Mexico's pre-decimal peso era (before the 1993 currency reform). "Centavo" simply means "cent," and one centavo was one-hundredth of an old peso. It circulated widely and survives in large numbers, which is why it stays inexpensive today.

Despite the source listing "latón" (brass) in one place, the composition is bronze. Here are the exact specifications:

• Denomination: 1 centavo
• Year: 1955
• Metal: Bronze
• Weight: 2.01 grams
• Diameter: 16.02 mm
• Edge: Plain (smooth)
• Mint: Casa de Moneda de México (mint mark "Mo")

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

Reverse (back): The face value "1" in large numerals, the year "1955," and the "Mo" mint mark of the Mexico City mint.

How much is a 1955 1 centavo worth?

Value is driven almost entirely by condition. Bronze coins that circulated pick up wear, spots, and corrosion, all of which push the price down toward the metal-plus-collectible floor. A clean, uncirculated example is the only version that brings real interest.

These are collector ranges, not guarantees. A bag of worn 1955 centavos is worth pocket change. The value lives in top-grade, well-struck examples with original color, and even those top out modestly for a common date.

The "it's old, so it's valuable" myth

Age alone does not make a coin valuable. The 1955 centavo is nearly 70 years old and still worth cents in worn condition, because millions were struck and many survive. What actually drives value in Mexican coins is genuine rarity (low mintage or few survivors), strong collector demand, and high grade. This coin checks none of those boxes as a common circulation issue.

If you have a larger group of old Mexican coins, the pieces worth checking carefully are silver ones. See our guide to Mexican silver coins and their content to sort the valuable metal from the base-metal filler.

Are there valuable errors?

Genuine mint errors (off-center strikes, die rotation, double strikes, or verified die varieties) can multiply the value of an otherwise common coin. The catch: most "errors" people spot in circulated coins are post-mint damage, meaning dents, scratches, and corrosion that happened after the coin left the mint. That kind of damage lowers value, it does not raise it. If you think yours shows a real minting error, post clear photos in the Pesoteca forum and let the community assess it before you get your hopes up.

How to tell if yours is genuine

This is a low-value coin, so counterfeits are rare, but it is still worth a quick check:

1. Weigh it. A genuine 1955 centavo weighs 2.01 grams. Use a jeweler's scale.
2. Measure it. Diameter should be 16.02 mm. Use calipers.
3. Look at the strike. Real coins have crisp relief and evenly distributed bronze color. Fakes often show flat, mushy detail or the wrong tone.

If the weight or diameter is off, or the design looks soft, be cautious.

Where to sell it

For a common coin like this, keep it simple. Options that make sense:

• A verified numismatic shop from the Pesoteca directory, which can appraise it on the spot.
• The Pesoteca buy-and-sell forum, where collectors trade directly.

Before you sell, photograph the obverse, reverse, and edge, and check your coin against the grade ranges above. Do not dump a coin to the first Facebook buyer without knowing its condition. And use our coin grading guide to place your piece on the scale accurately, since one grade up or down changes what it is worth.

The circulating centavo coins in Mexico during the second half of the 20th century were struck in alloys that changed with the cost of the metals: copper, bronze, and brass for 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 change of alloy generated a distinct variant of the same face value. 1955 corresponds to the period when this variant 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 entire era.
