10 Pesos 470th Anniversary of the Mexican Mint (2005): Silver Proof Value

If you inherited or found a 2005 Mexican 10 Pesos marked "470 Aniversario de la Casa de Moneda de México," here's the fast answer: it's a one-ounce fine silver proof coin, and in 2026 it's worth roughly 35 to 100 US dollars for a typical example, more if it's a flawless certified proof in its original packaging. It's not a rare fortune-maker, but it is real silver, which gives it a hard price floor.

What you actually have

This is a commemorative coin struck in 2005 by the Casa de Moneda de México (the Mexican Mint, the oldest mint in the Americas) to mark its 470th anniversary. "Casa de Moneda" simply means "mint," and "470 Aniversario" is the 470th anniversary.

The hard specs, which you should verify on your own coin:

• Denomination: 10 Pesos (face value only, ignore it, the silver is worth far more)
• Metal: .999 fine silver (99.9% pure silver)
• Weight: 33.73 grams (about one troy ounce of silver)
• Diameter: 40 mm
• Edge: plain (smooth)
• Finish: proof (mirror-like fields with frosted raised designs)
• Year: 2005 only, single year of issue

Because it holds close to a full troy ounce of pure silver, this coin will never be worth less than the melt value of its silver. That's your floor. As of recent silver prices, that floor sits in the 30 to 35 US dollar range, and it moves with the market.

What it's worth in USD

Most of these coins were sold in numismatic sets, not spent as money, so many survive in excellent shape. That's good and bad: good because yours is probably clean, bad because clean examples aren't scarce, so the premium over silver stays modest.

Condition	What it looks like	Approximate value (USD)
Handled / lightly worn	fingerprints, hairlines, no original packaging	30 to 40
Uncirculated proof, loose	sharp mirror fields, no case	40 to 65
Proof in original Banxico packaging	sealed capsule, certificate	60 to 100
Certified NGC/PCGS PF-69 or PF-70	graded, top condition	100 to 200+

These are guide ranges, not guarantees. Silver spot price sets the bottom; condition, original packaging, and certification set the top. A raw handled example is basically a silver round with a nice design. A certified PF-70 with paperwork is where the collector premium shows up.

Is it rare?

Honestly, no, not in the way that makes headlines. The exact mintage of this issue was not published by the Mexican central bank (Banxico), which usually points to a limited numismatic-set release rather than mass circulation. Limited is not the same as rare, though. Enough exist that you can find one for sale without much effort, which keeps prices reasonable. Don't expect a windfall.

How to tell if yours is genuine

Silver coins get counterfeited, so run these checks before you buy or sell.

1. Weigh it. A real one is 33.73 grams. A cheap kitchen scale reading well off that number is a red flag.
2. Measure it. 40 mm diameter. Fakes are often slightly off.
3. The ping test. Genuine .999 silver produces a long, high-pitched ring when you balance it on a fingertip and tap it lightly with another coin. Base-metal fakes sound dull and short.
4. Look at the finish. A true proof has deep mirror fields and crisp frosted relief. Blurry or grainy detail suggests a cast copy.
5. When in doubt, certify. For anything you believe is high grade, third-party grading from NGC or PCGS is the definitive answer. It costs money but it also raises resale value.

Use our coin grading and condition guide to figure out where your coin lands before you get it appraised.

Where to sell it

Since this is a bullion-backed silver coin, you'll always find a buyer. Your options, best to worst for getting a fair price:

• A verified numismatic dealer from the Pesoteca shop directory, who can appraise it on the spot.
• The Pesoteca buy-and-sell forum](/foro/compra-venta), where collectors deal directly.
• Local coin shows and reputable coin shops.
• Online marketplaces, which have decent prices but the most fakes. If you buy there, demand photos of the edge and the exact weight first.

Photograph the front, back, and edge, note whether you still have the original capsule and certificate, and check the ranges above before you accept any offer. Don't dump it on the first buyer who lowballs you.
