100 Pesos Mexico City Silver Coin (2005): Value & Prices

If you inherited or found a large bimetallic 100 Pesos coin from Mexico dated 2005 with "Ciudad de México" on it, here is the straight answer: it is worth money, mostly because of its silver core. In 2026, a typical example trades for roughly 20 to 45 USD, and mint-condition pieces in the original Banxico case can run higher.

This is not a coin that will make you rich, but it is far from face value. The old 100 pesos face value is worth about 5 US cents today, so nobody is spending this at a store. The value comes from the silver and from collector demand for the series.

What you actually have

This is one of the 100 Pesos state coins issued for the 180th anniversary of Mexico's federation. The Mexico City (Ciudad de México) coin belongs to the second, "cultural" phase of that program, released in 2005 with a satin finish.

The key detail for value: this is a bimetallic coin with a silver center. Specifications, which you should verify to confirm authenticity:

• Weight: 33.94 grams
• Diameter: 39 millimeters
• Composition: bimetallic (silver core in a base-metal ring)
• Edge: interrupted reeding (reeded in segments)

The outer ring carries the Mexican coat of arms (an eagle devouring a snake on a cactus), shared across the whole series. The inner silver core shows a cultural motif representing Mexico City. Confirm the exact design against the official Banxico catalog before you catalog your piece, since each state in the series has its own reverse.

What it is worth in 2026

Because the center is silver, this coin has a floor: it never drops below its melt value. Above that floor, condition and packaging drive the price.

Condition	Typical value (USD)	Notes
Circulated	18 to 28	Handled, some wear, no case
Uncirculated (loose)	25 to 40	No wear, but out of original packaging
Uncirculated in original Banxico case	35 to 55	Sealed blister/capsule adds a premium

These are collector ranges for a single coin. The full 32-coin second-phase set, complete and cased, sells for more as a unit than the coins added up individually. If you have one coin, treat it as a mid-value silver collectible, not a rarity.

Is it rare?

No, not in the numismatic sense. The 100 Pesos state series was produced in meaningful numbers and sold to collectors, so surviving examples are common. What gives it lasting value is the silver content and steady demand from people completing the 32-coin set. A single Mexico City coin is desirable but not scarce.

Where value can jump is in genuine mint errors: off-center strikes, die rotation, or double strikes that are verifiable. Be skeptical. Most "errors" posted online are post-mint damage (dings, corrosion, scratches), which lower value rather than raise it. If you think you have a real error, post clear photos on the Pesoteca forum and let the community weigh in.

How to tell if yours is genuine

Counterfeits of these coins exist, mostly aimed at the silver premium. Two quick checks catch most fakes:

1. Weigh it. Use a jewelry scale. A genuine coin is 33.94 grams. A fake is often noticeably off.
2. Measure the diameter. It should be 39 millimeters with calipers.

Also look at the strike: real coins have crisp, raised detail and clean color separation between the silver core and the ring. Flat relief, blurry lettering, or bleeding colors are red flags. When in doubt, compare against the coin grading guide or have a dealer confirm it in person.

Where to sell it

To sell without giving away the silver premium, use a verified numismatic shop from the Pesoteca directory, where a dealer values it on the spot, or the Pesoteca buy-and-sell forum to reach collectors directly. Photograph the obverse, reverse, and edge, and check the range in this page before you agree to a price. Avoid dumping it to the first offer on social media, where sellers routinely take less than the silver is worth.

The entry dedicated to Mexico City belongs to the first wave of the Cultural phase, issued in 2005 along with most of the set. Banxico called this second stage Motivos Emblemáticos and replaced the state coat of arms with a specific cultural symbol.

The reverse of the piece shows the facade of the Palacio de Bellas Artes, a work begun by Adamo Boari in 1904 and completed by Federico Mariscal in 1934. The Palacio de Bellas Artes blends art nouveau on its exterior with art deco in its interior. It houses murals by Diego Rivera, José Clemente Orozco, David Alfaro Siqueiros, Rufino Tamayo and Roberto Montenegro, and its stained-glass stage curtain from the Tiffany house was designed by Harry Stoner in 1913.

State context: Mexico City was the capital of the Mexica Empire from 1325 and of the viceroyalty from 1521. The Mo mint operated without interruption from 1535 to 1929, making it the oldest on the American continent. It was elevated from Federal District to a federal entity on January 29, 2016.

In the Mexican numismatic market the Cultural phase circulated less than the 2003 Coat of Arms and today tends to be found in higher grades because it reached the street late. Banxico's official mintages for this piece are not always published in the Economic Information System, but the figure reported to circulation tends to be around 250,000 pieces per state in the Cultural phase. Always confirm against the catalog of the complete 100 pesos States series before closing a large purchase.

The 2003 Coat of Arms sister of Mexico City is part of the first phase of the series, with the state's official coat of arms on the reverse. Hunting both pieces completes the set dedicated to Mexico City.
