10 Pesos 1 oz Silver World Cup 2026 (Monterrey)

If you have the 2026 Monterrey silver ounce, it is worth real money, but not for the reason most people assume. Its value comes from one troy ounce of .999 fine silver plus collector demand tied to the FIFA World Cup 2026, not from being "old" or "rare." As of 2026, expect a floor near the current silver melt value, with a premium on top for the theme and condition.

What this coin actually is

This is one of four one-ounce pure silver coins that Banco de México (Banxico, the Mexican central bank) issued for the FIFA World Cup 2026. Each coin in the set represents a Mexican host city, and this one carries the Monterrey design: the BBVA Stadium and the Cerro de la Silla, the saddle-shaped mountain that is the city's landmark.

Even though it says "10 Pesos" on it, that face value is symbolic. The coin is a bullion and collector piece, so its real value is driven by silver content and demand, not the number stamped on the front.

Technical data (keep these numbers)

Spec	Value
Metal	Silver .999 fine
Weight	31.103 g (1 troy ounce)
Diameter	40 mm
Finish	Mirror / proof-like
Issuer	Banco de México / Casa de Moneda
Series	FIFA World Cup 2026 (4-coin set)

These figures are your first authenticity check. A genuine coin weighs 31.103 grams and measures 40 mm. Off by a meaningful margin and you are likely looking at a fake.

What it's worth in 2026

There are two prices to understand here.

Melt value (the floor): One troy ounce of .999 silver is worth whatever silver trades at that day. Look up the current spot price of silver per ounce in USD, and that is roughly the minimum this coin should ever sell for. No genuine .999 silver ounce should trade below its melt value.

Collector premium (the upside): Because this is a themed World Cup 2026 issue with a mirror finish, it sells above melt. How much above depends on demand, whether it is a single coin or the full four-coin set, and condition. Sealed, spot-free proof pieces command more than handled coins with fingerprints or scratches.

Official pricing has been unusual for this issue. A leaked Banxico figure from June 2026 listed the coin at 2,071 pesos per piece for Bank of Mexico staff, and 8,284 pesos for the complete four-coin set. The public price from the Mint had not been published as of that date, which is exactly why a parallel resale market formed around these ounces. We cover that in The parallel market of the 2026 World Cup silver ounces.

Bottom line: as a recent, high-mintage bullion issue, this is not a five-figure rarity. It is a silver ounce with a modest, demand-driven premium. Anyone quoting you "thousands of dollars" for a single common example is inflating it.

Does condition matter?

Yes, and more than usual for a proof coin. These pieces were made with a mirror finish, and mirror surfaces show every flaw. The premium concentrates in coins that are spotless and in their original packaging.

• Sealed / untouched proof: highest premium.
• Handled, minor marks or milk spots: premium shrinks toward melt.
• Cleaned or scratched: treat as close to silver value only.

If you can, grade or at least photograph the coin under angled light to reveal hairlines and spots before you sell.

The set vs. the single coin

The Monterrey coin was sold as part of a four-city set. Complete, matched sets in original packaging usually sell for more than the sum of four loose coins. If you inherited or bought the full set, keep it together; splitting it often lowers total value.

How to tell if yours is genuine

1. Weigh it. Use a jewelry scale. It should read 31.103 g. Silver has a distinct density, so an underweight coin is a red flag.
2. Measure it. A caliper should read 40 mm across.
3. Inspect the relief. Genuine strikes have crisp, three-dimensional detail on the stadium and the Cerro de la Silla. Fakes look flat or mushy.
4. Be suspicious of bargains. Any offer far below the current silver melt value is a warning sign, not a deal.

Where to sell it (and get a fair price)

Because this is a precious-metal coin, sell only where you can show the piece and its weight before money changes hands.

• A verified numismatic shop from the Pesoteca store directory. They can value it on the spot against current silver prices and the collector premium.
• The Pesoteca buy-and-sell forum, collector to collector, which usually beats a walk-in buyback offer.

Before you sell, photograph the obverse, reverse and edge, check the current silver spot price, and compare offers against the melt floor. Do not dump it to the first Facebook buyer who lowballs you.

Monterrey is one of the three Mexican host cities confirmed by FIFA for the 2026 World Cup. It already hosted matches for the 1986 World Cup and returns forty years later with Estadio BBVA, opened in 2015, the most recent of the three Mexican venues for the tournament.

This is the 0.999 silver one-troy-ounce version (31.103 g) struck with a mirror finish. Unlike the circulating bimetallic piece, it does not enter circulation but the numismatic circuit: the mintage is far lower than the circulating coin, and its value is anchored to the spot price of silver plus a collector premium for the commemorative edition.

Banxico issued this piece within the World Cup 2026 set alongside the circulating bimetallic coin, the 0.999 gold 7.776 g version and its silver sisters from Mexico City, Guadalajara and Mexico Triple Host.
