How much is the 100 Pesos Tlaxcala 2003 (Bimetallic Silver) worth?
The market value of the 100 Pesos Tlaxcala 2003 (Bimetallic Silver) 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.

States of the Federation
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 inherited a large, heavy Mexican coin marked "100 Pesos" with a coat of arms in the center, you likely have one of the bimetallic State Series coins. The 2003 Tlaxcala issue is one of them, and the good news is that its center is actual silver. Most examples trade for roughly 20 to 45 USD, with high-grade or proof pieces reaching more. This is not a lottery-ticket rarity, but it is worth real money because of the metal alone.
What it is worth right now (2026)
The 100 Pesos Tlaxcala (KM# 683) is part of Mexico's bimetallic State Series, and its center disc is .925 silver. That silver content sets a hard floor under the price. Even a worn, circulated example is worth more than face value because you cannot melt the silver for less than what the market pays for the metal.
Expect these general ranges:
- Circulated (handled, scratched): around 18 to 25 USD, mostly driven by silver.
- Uncirculated (crisp, no wear): around 30 to 45 USD.
- Proof or certified high grade (NGC/PCGS MS68+ or PF69): 50 to 100 USD or more, depending on demand for that specific state.
These are collector prices between hobbyists, not what a pawn shop will hand you. A shop buying to resell will pay less.

The obverse carries the Mexican national coat of arms (the eagle) shared by every coin in the family. The reverse shows the Tlaxcala state coat of arms. The word "Escudo" simply means "coat of arms" in Spanish, so "100 Pesos Tlaxcala Escudo" just describes the design.
Why this coin has value, and why it is not a jackpot
Mexico issued this series to honor all 31 states plus Mexico City, giving each one its own coat of arms on the reverse. Tlaxcala belongs to the second phase of the program. Collectors chase these because completing the full state set is a genuine goal, and every issue has a spot in that set.
So the value comes from two honest sources: the real silver center, and steady collector demand for the set. What it is not is a rare error coin worth thousands. The mintages for these were large enough that no single common-date state coin commands a small fortune. If a listing claims your ordinary 2003 Tlaxcala is worth hundreds of dollars, that is wishful pricing, not the market.
Errors and varieties: read this before you get excited
Genuine mint errors (off-center strikes, die rotation, double strikes) can multiply a coin's value if a grading service confirms them. But most "errors" people post online are post-mint damage: dings, corrosion, or wear that happened after the coin left the mint. Those add nothing. If you think you have a real error, get it verified before you set your hopes on a big number.
How to tell if yours is genuine
- Weigh it. It should read 33.78 g on a jewelry scale. A significant difference is a red flag.
- Measure it. Diameter should be 39 mm with calipers.
- Check the two-tone contrast. The silver center and the outer ring should be cleanly separated, with sharp relief on the coat of arms.
- Look at the edge. It has interrupted reeding, not smooth.
Counterfeits typically miss the weight, show flat mushy detail, or have the wrong color split between metals. For a coin in this price band, sending it to NGC or PCGS is optional but worth it if you plan to sell an uncirculated or proof example.
Where to sell it
For the best price, sell to other collectors, not to whoever offers first. Options:
- A verified numismatic shop from the Pesoteca directory, which can appraise it on the spot.
- The Pesoteca buy-and-sell forum, where collectors trade directly and often pay set-building premiums.
Before you sell, photograph the obverse, reverse, and edge in good light, and compare the price range in this page. If you are still assembling the picture on the whole bimetallic State Series, post your coin in the Pesoteca forum and let the community weigh in on grade and value.

Historical context
The 100-peso Union of the States of the Mexican Republic series started in 2003 with the first stage, called the Coat of Arms stage because the reverse bears the official heraldry of each of the 32 states. The piece dedicated to Tlaxcala 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-pesos reform of 1993.
Tlaxcala has Tlaxcala de Xicohténcatl as its capital. It was established as a free and sovereign state in 1857. The reverse of the piece shows the official coat of arms of the state, without allusions to specific historical episodes: the central motif is the heraldic emblem. For mintages and economic circulation data of each piece of the series, the sources are the official Banxico reports; until they are verified in the CM10 catalog they are not reported on this listing.

The coat of arms of Tlaxcala shows an eagle with a bone over a tzompantli, a reference to the pre-Hispanic warrior heritage.
Tlaxcala was an ally of Hernán Cortés in the conquest of Tenochtitlan (1521). It is the smallest state in Mexico by area.
Tlaxcala 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 Tlaxcala during its first stage.
If you want to hunt this piece down in person or find specialized collectors in Tlaxcala, check the Tlaxcala store hub, where we document the state's verified stores with honest reviews, addresses and contact details.
If you collect the full series, your next target is the Cultural 2005 sibling of Tlaxcala, struck two years later with a state-specific iconographic motif instead of the official coat of arms. The full 100 Pesos States series also has the complete catalog with every sibling piece verified by Pesoteca.

Specific questions about this piece
Did Tlaxcala have a Mexican colonial mint?
No, Tlaxcala did not have a colonial mint during the viceroyalty. 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. You can see the full catalog in our colonial 8 reales series.
What is the difference from the 100 Pesos Tlaxcala 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 Tlaxcala.
Where can I buy the 100 Pesos Tlaxcala Coat of Arms 2003 today?
The main circuit for pieces in this series is the specialized numismatic market: auction houses, verified stores in the state, and private collectors. In the Tlaxcala store hub we document the local options with honest reviews. For UNC pieces or those with the original Banxico blister pack, the price rises between 3x and 8x the 100-peso face value.
Why did Tlaxcala 2003 (Bimetallic Silver) not have a colonial mint?
Tlaxcala 2003 (Bimetallic Silver) 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 Tlaxcala 2003 (Bimetallic Silver) 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.
Key historical event of Tlaxcala 2003 (Bimetallic Silver) (1521)
La República de Tlaxcala se alió con Hernán Cortés en 1519 y participó activamente en la Conquista de Tenochtitlan en 1521. Como recompensa, Tlaxcala mantuvo autonomía durante gran parte del Virreinato.
