100 Pesos Caballito 2011 (Herencia Numismática I): Value & Silver Content

If you inherited or found a large, two-tone 2011 Mexican 100 pesos with a horse and rider on it, here is the straight answer: it is a genuine silver coin, not a rare fortune. Most examples in circulated condition are worth roughly 100 to 500 pesos (a few US dollars to about 25 USD), while a certified high-grade piece can climb into the thousands of pesos. The value driver is condition and certification, not age.

This is the first coin in Mexico's Herencia Numismática ("Numismatic Heritage") series, launched in 2011. It revives the Caballito ("Little Horse"), one of the most admired designs in Mexican history: the original silver peso struck from 1910 to 1914 showing Liberty on horseback. So the design is old, but the coin you are holding was minted in 2011.

What you actually have

This is a bimetallic coin: a center core surrounded by an outer ring, similar in construction to a euro coin but larger and heavier. The specs matter because they are your first authenticity check.

The size and weight alone separate it from any modern circulating Mexican coin. At nearly 40 mm and 34 grams, it feels substantial in the hand. The center core carries silver content, which gives the coin a floor value tied to its metal, even if the collector market is soft.

Is it rare?

Honestly, no, not in the sense most people hope. The exact mintage of this issue was never published officially by Banxico (the Bank of Mexico). When a mint does not release a figure, it usually means the coin was distributed in limited numismatic sets rather than general circulation, so it is uncommon but not scarce enough to command big money on its own.

What this coin has going for it is that it is the No. I of the series. Anyone assembling the complete Herencia Numismática collection needs this piece, which keeps steady demand under it. That collector demand, plus the silver content, is why it holds value better than most modern commemoratives.

What drives the price

Age does not make this coin valuable. Three things do:

1. Grade. A coin with no wear, clean fields, and full detail on the rider is worth several times more than a handled, scuffed example. Proof and high uncirculated (MS-65 and above) pieces show the contrast between the silver core and the golden ring at its best, and that is what collectors pay for.
2. Certification. A coin slabbed by NGC or PCGS (the two major US grading services) sells for a premium because the buyer knows exactly what they are getting. For a piece worth more than a couple thousand pesos, certification is worth the cost.
3. Silver content. The center core is silver, giving the coin a metal floor. Even a beat-up example will not fall below its melt value.

Die errors (off-center strikes, die rotation, doubling) can multiply the value if they are genuine and verifiable. Be skeptical: most "errors" people post online are post-mint damage (dings, corrosion), not factory errors. If you think you have a real one, get a second opinion before you get excited.

How to tell if yours is genuine

Start with the numbers above. Your coin should weigh 33.967 grams and measure 39 mm. If it is off on either, you have a fake or a different coin. A kitchen scale accurate to 0.1 grams and a caliper settle most cases.

Next, look at the relief. Counterfeits tend to have flat, mushy detail. Compare the sharpness of the horse and rider against official Banxico images. The two-tone construction should show a clean, crisp seam between core and ring, not a blurry or peeling transition. For any coin you believe is worth real money, NGC or PCGS certification is the definitive answer.

Where to sell it

Your realistic options in the US and Mexico:

• A verified numismatic dealer will appraise it on the spot and pay fair market. If your coin might clear a few thousand pesos, a formal dealer with certified grading is worth the small fee.
• Serious collector groups and coin shows, where buyers know the Herencia Numismática series and will pay for the No. I.
• Online marketplaces can bring good prices but also carry the most fakes. If you sell there, provide clear photos of the front, back, and edge, plus the weight, so serious buyers trust the listing.

Before selling, photograph the obverse, reverse, and edge, and check the current price range for your grade. Do not dump it on the first offer from a social media group.

Unsure whether yours is a plain uncirculated example or something a dealer would fight over? Post clear photos of both sides and the edge in the Pesoteca forum and let collectors who track this series weigh in before you sell.

100 pesos silver Numismatic Heritage of Mexico series I, 2011, a reproduction of the 1910 Caballito Peso. A piece from the Bank of Mexico's Heritage project dedicated to the Caballito Peso, a silver coin issued between 1910 and 1914 with the design of an allegorical female figure riding a horse forward, the work of the French engraver Charles Pillet. The design was considered one of the most beautiful in twentieth-century world numismatics and coincided with the Centenary of Independence celebrated in 1910. Production was interrupted by the Mexican Revolution in 1914. The official weight of the Heritage reproduction is close to 31.10 grams with silver fineness 0.999. The matte-brightness finish combines a satin field with mirror relief, a technique characteristic of the project. Under the Bank of Mexico administration led by Agustin Carstens. The complete series I included six pieces in 2011 dedicated to emblematic numismatic milestones. They are collectible pieces for reproducing in modern format the most emblematic silver coin of the Porfiriato-to-Revolution transition and for documenting the French engraving legacy in Mexican coinage design of the early twentieth century.
