Mexican 1 Peso Coin (2010): Value & Facts

If you inherited or found a 2010 Mexican 1 peso coin, here is the honest answer first: in normal circulated condition it is worth its face value, roughly one Mexican peso, or a few US cents. This is a modern circulating coin, not rare, not silver, not a fortune. The exceptions that carry a premium are covered below.

This is the small two-tone coin with a brass-colored center ring inside a stainless steel outer ring. On one side is the Mexican national coat of arms (an eagle eating a snake, perched on a cactus), with the legend "ESTADOS UNIDOS MEXICANOS." On the other side is a large "1" with the year 2010 and the mint mark "Mo," which stands for the Casa de Moneda de México (the Mexican Mint), the oldest mint in the Americas.

What it's actually worth in 2026

Mexico produced this coin by the millions for everyday spending, so there is no scarcity to drive up the price. Value comes almost entirely from condition and packaging.

Condition	What it looks like	Approximate value (USD)
Circulated	Handled, scratched, dull	Face value, a few cents
Uncirculated	No wear, full luster, from a roll	About 25 cents to 1 dollar
Mint set / sealed	In original Banxico packaging	1 to 5 dollars

Those figures assume a standard, error-free coin. A genuine, verifiable mint error is the only thing that changes the math meaningfully (see below).

Technical specs (keep these to check yours)

• Denomination: 1 peso
• Year: 2010
• Composition: bimetallic (brass-alloy center, stainless steel ring)
• Weight: 3.95 grams
• Diameter: 21 mm
• Edge: reeded (grooved)
• Mint mark: Mo (Casa de Moneda de México)
• Series: part of the bimetallic 1 peso series, satin finish
• Era: Nuevos Pesos and current coinage

The obverse carries the national coat of arms in high relief with "ESTADOS UNIDOS MEXICANOS" arched above, the standard design used since the 1996 currency reform. The reverse shows the large denomination "1," the year, and the mint mark.

The myth: "it's old, it must be valuable"

A coin being from another country, or a decade old, does not make it rare. This 1 peso is recent, mass-produced, and made of common metals with no precious content. If someone online tells you a plain 2010 peso is worth hundreds of dollars, that is clickbait. The real premium coins in this denomination are error strikes and coins graded high by a service like NGC or PCGS.

When it IS worth more: mint errors

Genuine, verifiable striking errors (off-center strikes, die rotation, double strikes, or wrong-planchet varieties) can multiply the value well beyond face. The catch: most "errors" people post online are post-mint damage, dings, corrosion, or wear, not factory mistakes. A true error has to have happened during striking. If yours looks unusual, get a second opinion before assuming it's a windfall.

How to tell if yours is genuine

Counterfeiting a low-value circulating peso is rare, but here's how to check:

1. Weigh it. It should be 3.95 grams on a jewelry scale.
2. Measure it. 21 mm across with calipers.
3. Inspect the relief and colors. The two metals should be crisply separated, the eagle sharp, the edge cleanly reeded. Flat relief, blurry details, or smeared metal tones point to a fake or heavy damage.

Where to sell it

Be realistic: for a single circulated peso, no dealer will pay a premium. If you have uncirculated rolls, a sealed mint set, or a suspected error, then it's worth pursuing.

• Verified coin dealers in the Pesoteca shop directory will appraise a piece on the spot.
• The Pesoteca buy-and-sell forum connects you directly with collectors.
• Photograph the obverse, reverse, and edge before you sell, and compare your coin's grade against the coin grading guide.

Got a 2010 peso that looks off-center or double-struck? Post clear photos of both sides in the Pesoteca forum and let the community tell you whether it's a real error or just damage before you sell it short.

When Banxico dropped the N$ prefix from the peso starting in 1996, circulating pieces kept the same physical format as their Nuevos Pesos equivalents from the decree of June 22, 1992. This bimetallic 1-peso coin struck in 2010 is part of that continuity: same technical specifications, same base design with the National Coat of Arms on the obverse, only the face value visible on the reverse changed. That is why, when gathering dates, you see long sequences with very little variation.

For the Mexican collector building a collection by year, these pieces are the ones that fill the basic gaps before hunting the rare commemorative versions. Banxico documents mintages in its Monetary Circular CM10 since the year 2000, so for 2010 it is possible to verify the exact mintage against that source. Pesoteca catalogs each year as a distinct physical piece in the PSM System family C, following our convention of one ID per collectible piece, not per shared design.
