1938 Mexican 10 Centavos (Cupronickel): Value & Rarity

Most 1938 Mexican 10 centavos coins are worth a few dollars, not a fortune. This small cupronickel piece circulated hard, so worn examples trade for pocket change to a couple of dollars. The value only climbs when the coin is uncirculated and sharp, which is genuinely scarce. Here is what drives the price and how to check yours.

What this coin actually is

The 1938 10 centavos is a small cupronickel coin (a copper-nickel alloy, not silver) struck by the Casa de Moneda de México, the Mexican Mint. It is tiny: it weighs just 1.52 grams and measures 15 millimeters across, with a plain edge. If you inherited one, it feels almost delicate compared to the heavier silver coins of the same era.

"Centavos" are the fractional part of the Mexican peso, the same way cents work with the US dollar. In the 1930s and 1940s Mexico used base-metal coins like this one for everyday small change, so millions passed through the market and got worn down fast.

Is the 1938 10 centavos rare or valuable?

The short answer: the date is followed by collectors, but the coin is not a rarity in worn grades. What matters is condition. Because these tiny coins circulated heavily, the fine detail wears off quickly, so high-grade survivors are the ones that carry real value. A clean, uncirculated example with sharp relief and no dings is what sits at the top of the price range.

Here is the honest picture:

Condition	What it looks like	Approximate value (USD)
Worn (circulated)	Flat detail, scratches, dark tone	Under 1 to about 3 dollars
Fine to Extra Fine	Most detail visible, light wear	A few dollars to around 10 dollars
Uncirculated (mint state)	Full sharp detail, original luster	Higher, when certified and problem-free

These are general ranges for a common date in typical grades. A worn 1938 is a low-value coin. The premium only appears when the coin is genuinely uncirculated and, ideally, graded by a service like NGC or PCGS. A raw coin with heavy wear will not command the top figures no matter how old it looks.

Errors and varieties: separate the real from the noise

Genuine mint errors (off-center strikes, die rotation, doubled dies) can multiply the value of a small coin like this if they are verifiable. The catch is that most "errors" people post online are post-mint damage: dents, corrosion, and gouges that happened after the coin left the mint. Those add nothing to value. If you think you have a true striking error, get it looked at before you assume it is worth money.

How to check what yours is worth

1. Weigh and measure it. Use a jewelry scale and a caliper. A genuine 1938 10 centavos weighs 1.52 grams and measures 15 millimeters. Wrong weight or diameter is a red flag for a fake or altered piece.
2. Grade the condition honestly. Look at the high points of the design under good light. Sharp detail and original shine mean a better grade and a higher price. Flat, dark, or scratched surfaces mean a common circulated coin.
3. Photograph both sides and the edge. Clear photos are what any buyer or appraiser needs to give you a real number.
4. Get a second opinion before selling. A quick check against real market ranges protects you from underselling a good example or overpaying for a worn one.

Where to sell it

For a small coin like this, avoid dumping it on Facebook to the first person who offers. The safest routes:

• A verified numismatic shop from the Pesoteca dealer directory, which can value the coin in person without a middleman markup.
• The Pesoteca buy-and-sell forum, where you deal directly with collectors who know the series.

If you have a full box of Mexican coins, it is worth sorting the silver from the base metal first, since silver pieces have a floor at their metal value while cupronickel coins like this one are worth only what a collector will pay. Post photos, note the grade, and check the range on this page before you agree to any price.

Cent coins form the base of the Mexican monetary system. Banxico has modified their diameters, materials and alloys several times over the past decades to optimize minting costs. The 10-cent Cupronickel piece struck in 1938 belongs to the Banxico Numismatic Collection catalog documented on its official site.

For Mexican collectors, cent pieces gain value when they capture a change of material, a die error or an atypically low mintage. Banxico publishes annual mintages in CM10 since the year 2000. For earlier pieces the data may not be available. This entry follows the convention of the PSM System, one ID per distinct physical piece, not per shared design.
