10 Pesos Segundo Milenio (2000): 2 oz Silver Coin Value

If you inherited or found a large silver Mexican coin dated 2000 that reads "Segundo Milenio" (Second Millennium), you have a modern commemorative struck in 2 ounces of pure silver. The short answer for 2026: it is worth at least its silver melt value, and noticeably more if it is a clean proof still in its original Banco de México packaging.

This is not a rare colonial rarity worth a fortune. It is a bullion-heavy commemorative that has a hard floor tied to the silver price, with a modest collector premium on top when the surfaces are pristine.

What this coin actually is

The 10 Pesos "México Durante el Segundo Milenio" was issued by Mexico in 2000 to mark the turn of the millennium. It was struck as a proof, meaning mirror-like fields and frosted raised designs, the finish you get on coins made for collectors rather than for pocket change.

Exact specifications, which you should verify on your own piece:

• Denomination: 10 pesos
• Year: 2000 (single year of issue)
• Weight: 62.21 grams
• Diameter: 48 mm
• Metal: .999 fine silver (about 2 troy ounces of pure silver)
• Edge: reeded
• Finish: proof

That 2-ounce silver content is the key number. It is why the coin can never be "worthless," even in rough shape.

How much is it worth in 2026

Value breaks into two parts: the silver inside, and the collector premium for condition.

Silver floor. At roughly 2 troy ounces of .999 silver, the coin is always worth at least its melt value at the current spot price. That floor moves with the silver market, so check the day's silver price before you buy or sell.

Collector premium. A proof with hairlines, spots, or handling marks trades close to melt plus a small markup. A clean, spot-free proof, ideally still sealed in the original Banco de México capsule or blister, commands a premium over melt. Certified examples in high grade (NGC or PCGS PF-68 and up) bring the strongest numbers.

Condition	What you have	Approximate value (USD)
Damaged / cleaned	Scratches, milk spots, ex-jewelry	Silver melt value only
Circulated proof	Handled, minor hairlines	Melt plus a small premium
Choice proof, original packaging	Clean, sealed capsule	Melt plus a solid premium
Certified high grade	NGC/PCGS PF-68 or better	Highest premium over melt

We avoid a fake exact figure here because the base value tracks silver daily. Start from the spot price of 2 ounces of silver, then add the premium your condition earns.

The mintage question

The exact mintage for this issue is not published in official Banco de México figures the way circulating coinage is. Modern proof commemoratives like this were sold in limited collector sets, so surviving examples are finite but not genuinely scarce. Numbers you see quoted in forums are speculation, not confirmed data. Do not pay a rarity premium based on an unverified mintage claim.

Is it genuine?

Because the coin carries real silver value, counterfeits and altered pieces exist. Three quick checks:

1. Weight and size. A real one weighs 62.21 grams and measures 48 mm. Put it on a scale. If the numbers are off, stop there.
2. The ping test. Genuine .999 silver produces a high, sustained ring when you balance it on a fingertip and tap it gently. Fakes with base-metal cores sound dull and short.
3. Certification. For anything you plan to buy or sell above bullion value, a slab from NGC or PCGS removes all doubt about metal and grade.

Never buy sight-unseen. Ask any seller for clear photos of the obverse, reverse, and edge, plus a photo of it on a scale.

Where to sell it

For a coin whose value is mostly silver, sell where the buyer can weigh and inspect it:

• A verified numismatic shop from the Pesoteca directory, which values it on the spot and pays fairly against melt plus premium.
• The Pesoteca buy-and-sell forum, where collectors deal directly and know what a proof in original packaging is worth.
• Local coin shows and reputable dealer networks.

Before you sell, photograph all three sides, check today's silver spot price so you know your floor, and compare against the grade ranges above. Do not dump it to the first Facebook offer, and be cautious with open marketplaces where fakes and lowball buyers cluster.

Errors and varieties

Genuine mint errors (off-center strikes, die rotation, doubled dies) can multiply value when they are verifiable. Most "errors" posted online are post-mint damage: dings, corrosion, and milk spots, which lower value rather than raise it. If you think you have a real error, post it to the Pesoteca forum and let the community weigh in before you assume it is worth extra.
