10 Pesos Bimetallic Coin (2002): Value and Facts

If you found a Mexican 10 pesos coin dated 2002, here is the honest answer: it is worth its face value, about 55 US cents at current exchange rates, unless it is in flawless uncirculated condition or carries a genuine mint error. This is a circulating coin, not a rarity. Millions were struck for daily use.

That does not mean it is worthless. It means you should know exactly what drives its price before you get excited or sell it short. Below we break down the facts, the real value range, and how to check if yours is one of the few worth more than pocket change.

What this coin actually is

The 10 pesos coin of 2002 is a bimetallic piece, meaning it has two parts: an outer ring in one metal tone and a central core (the "plug") in a different tone. That two-color look is the same design you see across the modern Mexican 1, 2, 5, 10, and 20 peso coins.

Here are the exact specs, straight from the mint:

Specification	Detail
Denomination	10 pesos
Year	2002
Weight	10.328 g
Diameter	28 mm
Edge	Reeded (grooved)
Type	Bimetallic (ring + core)
Struck by	Casa de Moneda de México (Mexican Mint)
Obverse	National Coat of Arms (eagle and serpent)

This denomination comes from the monetary system launched in 1993 with the "Nuevos Pesos" (New Pesos) reform, which later settled into the bimetallic family still in circulation today. It contains no silver or gold. Do not expect any melt value beyond the base metals, which are worth a fraction of the face value.

What it is worth in 2026

For most people, the 2002 10 pesos coin is worth exactly 10 pesos, roughly 50 to 60 cents USD depending on the exchange rate. A worn coin pulled from change or an inherited jar is spending money, nothing more.

Where it gets interesting is condition. Collectors will pay a small premium for a coin in UNC (uncirculated) grade: no wear, no bag marks, full original luster, and a crisp contrast between the ring and the core. Even then, we are talking a few dollars, not hundreds. A certified high-grade example (graded by NGC or PCGS, the two major US grading services) can bring more, but the demand for a common modern circulating coin is limited.

The realistic value range:

• Circulated: face value, about 55 cents USD.
• Uncirculated (raw): a few dollars, mostly to date collectors.
• Certified high grade or genuine mint error: potentially higher, but you need proof it is real.

The "error coin worth thousands" myth

Social media is full of videos claiming ordinary Mexican coins are worth thousands of dollars because of a mark or defect. Be skeptical. Genuine mint errors do exist and can multiply a coin's value: off-center strikes, die rotation, double strikes, and true die varieties. When verified, these are worth real money to specialists.

The catch: the vast majority of "errors" people post online are post-mint damage, not factory errors. Scratches, corrosion, dents, and stains from decades in circulation are not errors and add nothing to value. If you think you have a genuine mint error, get it looked at before you assume it is a jackpot.

How to tell if yours is genuine

Counterfeits of a low-value circulating coin are uncommon, but here is how to check:

1. Weigh it. A jewelry scale should read close to 10.328 g. A significant deviation is a red flag.
2. Measure it. A caliper should read 28 mm across.
3. Inspect the strike. Genuine coins have sharp relief and clean color separation between ring and core. Flat detail or smeared colors suggest a fake.
4. Check the edge. It should be reeded (grooved), not smooth.

Where to sell it

If your coin is just circulated, honestly, the easiest place to "sell" it is to spend it or exchange it at a bank in Mexico. It is legal tender.

If it is uncirculated or you believe it has a real error, do this before selling:

• Photograph the obverse, reverse, and edge in good light.
• Compare your grade against the value range above.
• Take it to a verified coin shop in the Pesoteca directory for an in-person appraisal, or list it in the Pesoteca buy-sell forum among collectors.

Avoid dumping it on Facebook Marketplace to the first buyer.

When Banxico dropped the N$ prefix from the peso starting in 1996, the circulating pieces kept the same physical format as their Nuevos Pesos equivalents from the decree of June 22, 1992. This bimetallic 10-peso coin struck in 2002 is part of that continuity: same technical specifications, same base design with the National Coat of Arms on the obverse, only the face value shown on the reverse changed. That's why, when you gather dates, you see long sequences with very little variation.

For the Mexican collector building a year-by-year set, these are the pieces that fill the basic gaps before you go hunting the rare commemorative versions. Banxico documents the mintages in its Monetary Circular CM10 from the year 2000 on, so for 2002 you can verify the exact mintage against that source. Pesoteca catalogs each year as a distinct physical piece under the PSM System, family C, following our convention of one ID per collectible piece, not per shared design.
