Mexican 10 Pesos 2007 Silver Coin: 180th Anniversary of the Union

If you inherited or found a 2007 Mexican 10 pesos coin marked with the 180th Anniversary of the Union, here is the honest answer: its value floor is its silver content. This is a large .999 fine silver coin holding about 1.216 troy ounces, so its melt value in 2026 runs roughly USD 25 to 40 depending on the spot price. A pristine, certified example can bring more, but this is a modern commemorative, not a rare antique.

What you actually have

This is a heavy silver commemorative, not a pocket-change coin. Do not confuse it with the small everyday Mexican 10 pesos coin (a bi-metallic circulation piece worth well under a dollar). The two look nothing alike once you weigh them.

The specifications matter because they set the value and prove authenticity:

• Denomination: 10 pesos
• Year: 2007 (single year of issue)
• Weight: 37.84 grams
• Diameter: 40 mm
• Metal: .999 fine silver (99.9% pure)
• Silver content: about 1.216 troy ounces
• Edge: reeded

The coin was struck for the 180th Anniversary of the Union of the States of the Republic into a federation. This particular piece belongs to the state series and depicts Nayarit (second stage of the state commemorative program). It is part of Mexico's modern "Nuevos Pesos" era.

How much is it worth in 2026?

Start with the metal. At current silver prices, the 1.216 ounces of pure silver inside are worth roughly USD 25 to 40. That is your guaranteed floor. No matter how worn the coin is, a bullion buyer will pay close to melt value for it because the silver is real and refinable.

Above that floor, condition and certification decide everything:

Condition	Approximate value (USD)	Notes
Circulated / handled	25 to 40	Essentially melt value
Uncirculated, no capsule	40 to 60	Clean surfaces, original luster
In original Banxico blister/capsule	55 to 90	Packaging matters to collectors
Certified MS/PF high grade (NGC or PCGS)	90 and up	Premium for a top graded example

These are guidance ranges, not fixed quotes. The silver spot price moves daily, and demand for Mexican state commemoratives is thinner in the US market than for classic pieces like the Centenario gold coin or the Onza Libertad silver bullion. If you want a hard number, weigh the coin, multiply the silver content by the day's spot price, and treat that as the minimum.

Is it rare?

Here is the honest read. Banxico did not publish an official mintage figure for this specific issue, which usually means it came out in limited numismatic sets rather than for wide circulation. Low visibility is not the same as extreme rarity, though. Modern silver commemoratives from the 2000s are generally available to anyone willing to look, and they trade close to their metal value most of the time.

Do not expect a small-town-auction windfall. The stories you see online about ordinary modern coins "worth millions" do not apply here. What gives this coin real, verifiable worth is the silver you can hold in your hand.

Errors and variants

Because it was struck in a single year (2007), there are no date variants to hunt. There can be minor die varieties (off-center strikes, die rotation, doubling) that a professional grader would flag. Genuine mint errors can add a real premium.

Be skeptical. Most "errors" people post online are post-mint damage: scratches, dings, and corrosion, none of which add value. If you think you have a true error, get a second opinion before you count on it.

How to tell if yours is genuine

Silver is easy to verify with three quick checks:

1. Weigh and measure it. A genuine coin weighs 37.84 grams and measures 40 mm. If your piece is lighter or a different size, it is not the real thing.
2. The ping test. Balance the coin on a fingertip and tap it lightly. Real .999 silver rings with a clear, high, sustained tone. A fake made of base metal sounds dull and short.
3. Professional grading. For anything you believe is worth a real premium, send it to NGC or PCGS. Certification is the only way to settle authenticity and grade with certainty, and it raises the resale value.

Where to sell it

You have a few solid options in 2026:

• Coin dealers and bullion buyers. Any dealer will pay at least melt value for a .999 silver coin. Bring the weight so you can check their offer against spot.
• The Pesoteca buy-and-sell forum, where collectors of Mexican coins trade directly and understand what a state commemorative is worth.
• The verified Pesoteca dealer directory, which lists established shops that will appraise the coin on the spot.
• Online marketplaces, which can bring good prices but also carry more counterfeits. Always show clear photos of the front, back, and edge, and state the exact weight.

Photograph the obverse, reverse, and edge before you list or sell. A buyer who can see the reeded edge and confirm the weight will pay you fairly and fast.

Have one of these sitting in a drawer and not sure what condition it's in? Post clear photos on the Pesoteca forum and let collectors help you pin down the grade before you decide to sell.
