How much is the 100 Pesos Nayarit 2003 (Coat of Arms): Value & Silver Content worth?
The market value of the 100 Pesos Nayarit 2003 (Coat of Arms): Value & Silver Content is not yet documented with enough data to give a firm range. Weigh and measure your piece, compare it against the specifications, and check the forum for a second opinion.
The real price depends on four factors: the grade of preservation (a circulated piece is worth the low end of the range; an uncirculated one, or one still in its official blister pack, the high end), the finish (satin vs mirror/proof), the rarity within the series based on the mintage, and the metal spot price on the day of the deal when the piece is silver or gold. Check the value-by-grade table above and compare with equivalent pieces before buying or selling.

The 64 pieces of the 180th Anniversary series
This coin is part of the series that dedicated one piece to each Mexican state. Two phases: Heraldic (2003) and Cultural (2005-2007).
Description
If you found a heavy two-tone Mexican 100 pesos coin dated 2003 with a state seal on it, here's the fast answer: the center is real .925 sterling silver, so it has a floor value at melt (roughly the price of about 12.6 grams of silver, since the silver center weighs part of the total), and most examples trade in the range of a few dollars over silver to around 15 to 30 USD in nice uncirculated condition. This is a modern commemorative, not a rare antique, so nobody is retiring on one.
What you actually have
This is the 100 Pesos Nayarit (Coat of Arms) issued in 2026 terms as part of a 2003 series. Mexico's central bank, Banco de México (Banxico), released a 32-coin set called "Unión de los Estados de la República Mexicana" (Union of the States of the Mexican Republic). Each Mexican state got its own 100 pesos coin. This one honors the state of Nayarit, on the Pacific coast, whose capital is Tepic.
The reverse shows the official coat of arms of Nayarit: an eagle with arrows and a sun, referencing the "sun of the north" and the region's Huichol Indigenous peoples. The obverse is shared across all 32 coins in the set: the Mexican national coat of arms (an eagle on a cactus with a serpent) inside the silver center, with the denomination 100 pesos.
Specifications (keep these to spot a fake)
| Feature | Detail |
|---|---|
| Denomination | 100 pesos |
| Year | 2003 (first stage of the series) |
| Weight | 33.78 grams |
| Diameter | 39 mm |
| Construction | Bimetallic: sterling silver center (.925), aluminum-bronze outer ring |
| Edge | Interrupted reeding |
| Finish | Satin |
The silver center is what gives this coin a hard floor. Sterling silver is 92.5 percent pure. That means even a worn, common example is never worth zero: it is always worth its silver content at minimum.
What it's worth in USD
Be realistic. These were produced as collector and semi-circulating commemoratives, and there are plenty around.
| Condition | Approximate value (USD) |
|---|---|
| Circulated / handled | Melt value of the silver center, a few dollars |
| Uncirculated (BU) | Around 12 to 25 USD |
| Certified high grade (NGC/PCGS MS67+) | 30 to 60 USD, occasionally more |
The swing depends on grade and whether the coin is certified. A raw coin sitting in a drawer for 20 years usually falls at the lower end. A pristine, professionally graded example is where the small premiums appear.
The two Nayarit 100 pesos coins (don't confuse them)
Banxico ran the series in two stages. The 2003 coin (this one) uses the state coat of arms. In 2005, Banxico issued the Nayarit Cultural 2005 coin, which uses a cultural image specific to the state instead of the official seal. Collectors who want the complete Nayarit pairing need both. The 2005 issue generally carries a slightly higher premium because it was made in smaller numbers, but the same rules apply: silver floor, modest collector demand.
The myth to ignore
Most people who inherit one of these assume that because it says 100 pesos and looks impressive, it must be valuable. It is not a fortune coin. These are modern issues from 2003, widely available, and their main worth is the silver inside. Anyone offering you hundreds of dollars for a single common one is either buying a top-graded example or making a mistake in your favor.
How to check what yours is worth
- Weigh and measure it. Use a jewelry scale and a caliper. It should hit 33.78 grams and 39 mm. Wrong weight or diameter, flat relief, or bleeding colors between the two metals are red flags for a fake.
- Grade it honestly. Handling marks, scratches and toning drop the value toward melt. A coin that looks flawless under a light may be worth getting certified.
- Sell it right. For a clean sale, use a verified numismatic shop from the Pesoteca shop directory, which appraises on the spot, or list it among collectors in the Pesoteca buy-and-sell forum. If you're near Nayarit, check the Nayarit shops hub for reviewed local dealers. Photograph the obverse, reverse and edge before you sell, and avoid dumping it to the first Facebook offer.

Historical context
The 100-peso Unión de los Estados de la República Mexicana series began in 2003 with the first stage, called the Escudo (Coat of Arms) stage because the reverse carries the official arms of each of the 32 states. The piece dedicated to Nayarit is part of that first block of 32 coins, issued by Banxico under the framework of the Monetary System that has governed the modern peso since the new-peso reform of 1993.
Nayarit has Tepic as its capital. It was established as a free and sovereign state in 1917. The reverse of the piece shows the state's official coat of arms, with no reference to specific historical episodes: the central motif is the heraldic emblem. For mintages and circulation-economics data for each piece in the series, the sources are Banxico's official reports; until they are verified in the CM10 catalog they are not reported on this listing.

The coat of arms of Nayarit shows an eagle with arrows and the sun, an allegory of the northern sun and the indigenous Huichol peoples.
Nayarit was the Territory of Tepic until 1917, when it became a state. It is home to Huichol communities that remain active to this day.
Nayarit did not have a colonial mint during the Mexican viceroyalty, but it joined Banxico's official commemorative program when the Bank of Mexico made the "Union of the States of the Mexican Republic" series official in 2003. This bicolor 100-peso piece is the first and only official coin dedicated specifically to the state of Nayarit during its first stage.

Specific questions about this piece
Did Nayarit have a Mexican colonial mint?

The active Mexican colonial mints were Mexico City (Mo, the most important), Zacatecas (Zs), Guadalajara (Ga), Guanajuato (Go), Durango (Do), Chihuahua (CH), Oaxaca (Oa, insurgent), San Luis Potosí (Pi, insurgent) and a few others of lower volume.

What is the difference from the 100 Pesos Nayarit Cultural 2005?
The Coat of Arms 2003 version (this one) shows the state's official coat of arms on the reverse. The sibling Cultural 2005 version shows an iconographic motif representative of the state (a historical figure, a monument, a cultural element) instead of the coat of arms. Both share the bimetallic format and composition. Collecting both is what completes the 100 Pesos set of Nayarit.
Where can I buy the 100 Pesos Nayarit Coat of Arms 2003 today?

Why did Nayarit 2003 (Coat of Arms): Value & Silver Content not have a colonial mint?
Nayarit 2003 (Coat of Arms): Value & Silver Content did not have an operating mint during the Spanish viceroyalty. The active Mexican colonial mints were Mexico City (Mo, the most important and oldest on the continent), Zacatecas (Zs), Guadalajara (Ga), Guanajuato (Go), Durango (Do), Chihuahua (CH), Oaxaca (Oa, insurgent) and San Luis Potosí (Pi, insurgent).
The main reason was economic: mints were only established in regions with enough silver mining output to justify the infrastructure. The silver circulating in Nayarit 2003 (Coat of Arms): Value & Silver Content during the colonial era came mainly from the central Mexico City mint. That is why this bicolor 100-peso piece from 2003 is the first official coin dedicated specifically to the state.

Frequently asked questions
How much is the 100 Pesos Nayarit 2003 coin worth?

Is the 2003 Nayarit 100 pesos coin rare?
No. It is a modern commemorative from a 32-coin series released by Banco de México in 2003, and plenty exist. Its value comes from the silver content and modest collector demand, not scarcity. High-grade certified examples are the only ones that carry a real premium.

How can I tell if my Nayarit 100 pesos coin is genuine?
