20 Centavos 2007 (Mexico): Value & What to Look For

If you inherited a jar of Mexican coins and found a small gold-colored 20 centavos dated 2007, the honest answer is this: in circulated condition it is worth its face value, roughly 1 to 2 US cents. A pristine uncirculated example might bring a couple of dollars from a collector. This is a common circulation coin, not a rarity.

That is the value-first truth most sites bury under history. Now here is everything you actually need to check yours.

What you have

The 2007 20 centavos is a small brass-colored coin from the Casa de Moneda de México (the Mexican Mint). "Centavos" are cents, the fraction of the peso, so 20 centavos is one-fifth of a peso. It is struck in aluminum-bronze, an alloy that gives it a golden tone, which is why it looks different from the larger silvery nickel coins in the same handful.

Specs to match against yours:

• Weight: 3.04 grams
• Diameter: 19.5 mm
• Edge: plain (smooth, no reeding)
• Composition: aluminum-bronze (gold-colored, not silver, not gold)
• Obverse: the Mexican national coat of arms, an eagle devouring a serpent
• Reverse: the numeral 20 with the year

This type belongs to the coinage that began with the 1992 currency reform (the "Nuevos Pesos"), when Mexico restructured its money and brought centavos back as the fraction of the peso.

Is it rare or valuable?

No. This is a workhorse circulation coin, minted in large numbers and used daily for small change. Being from 2007 does not make it old enough or scarce enough to command a premium. Age alone almost never creates value in modern coins; mintage, survivors in top grade, and collector demand do.

Where a tiny premium can appear is condition. Because these circulated heavily, most survivors are worn. A coin that never entered circulation, with full original aluminum-bronze luster and no scratches, is what a collector of a Mexican centavo year set will actually pay for. Even then, we are talking a couple of dollars, not a fortune.

Coin	Year	Grade	Approximate value (USD)
20 Centavos, aluminum-bronze	2007	Circulated (worn)	Face value, about 0.01 to 0.02
20 Centavos, aluminum-bronze	2007	Uncirculated, full luster	1 to 3
20 Centavos, aluminum-bronze	2007	Certified high grade (MS65+)	5 to 15, if a buyer wants it

Those certified-grade figures assume you actually pay to have it graded by NGC or PCGS, which costs more than the coin is worth. For a common date like this, grading only makes sense if you suspect a genuine mint error.

The "error coin" question

Genuine mint errors (off-center strikes, die rotation, double strikes, and true die varieties) can multiply the value of an otherwise common coin. The catch: most "errors" people spot on their coins are post-mint damage, dents, corrosion, or wear, not factory mistakes. A real error was created at the moment of striking and shows consistent, mint-caused features.

If you think yours is off-center or doubled, do not sand it, clean it, or scrub it. Photograph it and get a second opinion before assuming it is worth money.

How to tell if yours is genuine

Counterfeiting a 20-centavo coin makes no economic sense, so fakes are rare. Still, to confirm:

1. Weigh it on a jewelry scale. It should read 3.04 grams.
2. Measure it with calipers. It should be 19.5 mm across.
3. Check the edge. It should be plain and smooth.
4. Look at the relief. Genuine coins have crisp detail; fakes often show flat, mushy design and uneven color.

Wrong weight, wrong diameter, or flat lifeless detail are the giveaways.

Where to sell it

Be realistic: a single common 20 centavos is not something a dealer will pay much for. Your options:

• A verified coin shop from the Pesoteca dealer directory can appraise it on the spot.
• The Pesoteca buy-and-sell forum connects you with collectors, useful if you are completing or selling a Mexican centavo year set.
• If you have a full run of dates or a bag of mixed Mexican coins, sell them as a lot rather than one by one.

Before selling anything, photograph the obverse, reverse, and edge, and compare your coin's condition to the value table above.

Have a jar of mixed Mexican coins and no idea which ones are worth setting aside? Post clear photos in the Pesoteca forum and let collectors tell you which dates actually matter.

Context of the twenty-centavo piece of the year 2007

This twenty-centavo coin (KM#548) was struck by the Mexico City Mint in 2007, under the presidency of Felipe Calderon Hinojosa. It is part of the family of circulating pieces in an alloy of aluminum bronze with nickel that Banxico issued between 1992 and 2009, with a 19.5 mm diameter and 2.26 g weight.

The year in Mexico. It is the first full year of Felipe Calderon's term and the first of the National Security Strategy, which sent the Army into the streets in several states to combat drug trafficking. The Public Security Contributions Fund was also created. That year, according to INEGI's INPC, annual inflation closed at 3.76% and the Bank of Mexico's FIX exchange rate ended the year at 10.87 pesos per dollar.

How it circulated. In 2007 these pieces circulated with controlled inflation. They served to complete exact payments at gas stations, convenience stores and transport. The Metro fare was still 2 pesos, though in several cities the urban bus already charged 6 pesos.

Numismatic note. The 2007 die is the first complete minting under the Calderon administration. The dies were renewed to keep the sharpness of the eagle engraving. The obverse design is Banxico's official National Coat of Arms and the reverse shows the face value alongside the minting year. Between years the design remains identical and only the engraved date changes, so the visible difference is minimal. Internal die variations, when they exist, are documented in the Bank of Mexico's catalog.
