Mexican 10 Pesos 2006 Silver (180th Anniversary): Value Guide

If you inherited a large silver Mexican 10 pesos coin marked with a Mexican state and "180 Aniversario," the first thing to know: it is real silver, and that gives it a hard price floor. This is a 37.84-gram, .999 fine silver coin (about 1.11 troy ounces of pure silver), so in 2026 it is never worth less than its melt value, usually somewhere in the 30-plus USD range depending on the silver spot price. Whether it is worth more than that comes down to grade and demand.

What you actually have

This is a bullion-style commemorative from Mexico's state silver series, issued in 2006 for the 180th anniversary of the union of the Republic's states into a federation. The reverse of your specific coin honors a single state (the source example is Campeche, second stage of the program). It carries a face value of 10 pesos, but that number is meaningless for value: the metal alone is worth far more than 10 pesos.

Key specifications, unchanged and worth confirming on your piece:

• Metal: silver, .999 fine (99.9% pure)
• Weight: 37.84 grams (about 1.11 troy ounces of pure silver)
• Diameter: 40 mm
• Edge: reeded (grooved)
• Year: 2006 (single year of issue for this design)

That 40 mm size and 37.84 g weight are your first authenticity check. A coin that is lighter, smaller, or magnetic is not the real thing.

What it is worth in USD

Here is the honest answer most sellers won't give you: this is primarily a silver coin, not a rarity. Its value tracks silver first, condition second.

Condition	What it means	Approximate value (USD)
Circulated / handled	Scratches, fingerprints, toning	Melt value, roughly 30 to 45
Uncirculated (raw)	No wear, original luster	45 to 90
Certified MS-65+ (NGC/PCGS)	Graded gem, sealed in slab	90 to 300+

The ranges move with the silver spot price, so the melt floor rises and falls day to day. A single graded coin in top condition can pull the higher figures at auction, but the average inherited example, handled and unslabbed, sits near melt plus a modest collector premium.

Do not expect life-changing money from this piece. It is a solid, liquid silver coin with a small collectible upside, not a five-figure rarity. If you want to understand what separates a melt-value coin from a real prize, our guide to Mexican coin grading walks through the differences.

The myth to ignore

Because these coins are big, heavy, and carry a state seal and an anniversary date, people assume they are old and priceless. They are not old (2006), and they were made as collector bullion, not as scarce circulating money. The exact mintage of individual state versions is not always published, but these were sold to collectors, so surviving examples are not truly rare. "180th Anniversary" on the coin does not mean it is 180 years old. It commemorates an event from 1824; the coin itself is a modern strike.

How to tell if yours is genuine

Silver coins this size are counterfeited, so verify before you sell or buy.

1. Weigh it. A real one is 37.84 grams. Off by more than a few tenths of a gram, be suspicious.
2. Measure it. 40 mm across. Fakes are often slightly small.
3. Magnet test. Silver is not magnetic. If it sticks, it's fake.
4. Ping test. Genuine .999 silver rings with a high, sustained tone when gently balanced and tapped. Base-metal fakes sound dull and short.
5. Get it slabbed. For anything you think is in top grade, certification by NGC or PCGS is the definitive answer and adds resale value.

Where to sell it

Because the value is close to melt, your job is to avoid selling below silver spot and to skip anyone who lowballs you.

• Coin dealers and bullion buyers: the fastest cash. Expect an offer near melt for circulated pieces. Get more than one quote.
• A verified numismatic shop: use the Pesoteca dealer directory to find a reputable buyer who values it on the spot and pays close to fair value.
• Collector marketplaces: the Pesoteca buy-and-sell forum reaches people who actually collect the state series and may pay a premium for a nice example or one that completes their set.
• Online listings: possible, but this is also where fakes and lowball offers concentrate. Photograph the obverse, reverse, and edge, and state the exact weight.

One rule for silver: only deal with a buyer who will weigh the coin in front of you and quote against the current spot price. If someone offers you 10 pesos (face value) for it, walk away; they are trying to steal an ounce of silver.

Have one of the state coins and not sure which state or grade you're holding? Post clear photos of both sides and the edge in the Pesoteca forum and the community will help you pin down exactly what it is and what it should sell for.
