5 Pesos Belisario Domínguez 2009: Value & Prices

If you found a Mexican 5 pesos coin dated 2009 with Belisario Domínguez on it, here is the honest answer: the regular circulation version is worth close to face value, roughly 25 to 50 US cents to a collector. The silver proof version, still sealed in its Banco de México case, is the one that carries real value. Here is how to tell them apart and what each is actually worth in 2026.

Which version do you have?

This is the single most important question, and it decides whether your coin is worth pocket change or a modest premium. Two very different coins share the same 2009 design.

1. The circulation coin. This is the bimetallic 5 pesos that went into everyday change across Mexico. If yours came from a cash drawer, a coin jar, or loose in a wallet, it is almost certainly this one. It is common. Worn examples are worth face value. Even a crisp uncirculated one rarely brings more than 1 to 2 US dollars from a collector.

2. The silver proof. Banco de México (Banxico, Mexico's central bank) also struck a limited proof version with a .925 sterling silver center. It was sold sealed in an official Banxico presentation case with a mirror-like finish. This is the collectible one. If your coin is loose, it is the circulation version. If it is encapsulated in a hard plastic holder inside a box with paperwork, you may have the proof.

The specifications (both versions)

Feature	Detail
Denomination	5 pesos
Year	2009
Weight	9.76 g
Diameter	30.52 mm
Edge	Plain (smooth)
Composition	Aluminum-bronze outer ring, center is .925 silver on the proof version
Finish	Proof (encapsulated) and regular circulation
Program	Centenario de la Revolución Mexicana (Centennial of the Mexican Revolution)

The coin honors Belisario Domínguez, a senator from Chiapas killed under the Huerta regime. It is one of several designs in the Centennial of the Mexican Revolution series Banxico released in 2009 and 2010.

What is it actually worth?

There is no auction record putting this coin in the thousands. This is a modern commemorative from 2009, not a scarce classic. Value comes down to which version you have and its condition.

Version	Condition	Realistic value (USD)
Circulation	Circulated (worn)	Face value, about 0.25 to 0.30
Circulation	Uncirculated	1 to 2
Silver proof	Sealed in Banxico case	15 to 40, depending on demand and completeness of the set

These are collector-to-collector figures. A dealer buying to resell will offer less. The proof range moves with silver spot price and how much of the original packaging survives. A proof with a scratched capsule, missing certificate, or damaged box sells at the low end.

The myth to ignore

Social media posts claim modern Mexican commemoratives like this are worth hundreds or thousands. For the ordinary 2009 Belisario Domínguez 5 pesos, that is false. It was made for circulation and millions of people handled it. Age alone does not make a coin valuable. What drives value is genuine scarcity, collector demand, condition, and metal content. This coin has real silver only in the proof version, and even that trades at a modest premium over its silver weight, not a fortune.

If you are curious about which Mexican coins do command serious money, that is a separate conversation about pieces like the gold Centenario and early Republic silver, not everyday commemoratives.

How to tell if yours is genuine

Fakes of low-value modern coins are uncommon because there is little profit in it, but it is worth a two-minute check.

• Weigh it. A genuine coin is 9.76 g. Use a jewelry scale. A significant deviation is a red flag.
• Measure it. Diameter should be 30.52 mm. Use calipers.
• Check the strike. Genuine coins have sharp, well-defined relief. Flat, mushy detail or uneven coloring between the ring and center suggests a problem.
• Inspect the edge. It should be plain (smooth), not reeded.

"Error coins" and variants

Collectors do recognize genuine minting errors (off-center strikes, die rotation, doubled strikes) that can raise value on any coin. Be skeptical, though. Most "errors" shared online are post-mint damage: dings, corrosion, and scratches from circulation, not mistakes made at the mint. Those add no value. If you think you have a true error, post clear photos of the front, back, and edge in the Pesoteca forum and let the community weigh in.

Where to sell it

For the circulation version, honestly, it is worth more as a keepsake than the effort to sell. For the silver proof, do it right:

• A verified numismatic shop from the Pesoteca dealer directory can appraise it in person and make an offer on the spot.
• The Pesoteca buy-and-sell forum connects you directly with collectors, which usually beats a dealer's buy price.

Photograph the coin (front, back, and edge) and, for the proof, include the case and any paperwork. Check the price ranges above before you accept anything. Do not dump it on the first buyer who responds to a social media post.

Belisario Domínguez Palencia: physician and senator from Chiapas, martyr of Maderismo

Belisario Domínguez Palencia (1863-1913) was a physician and senator from Chiapas, a martyr of Maderismo during the Mexican Revolution.

Domínguez delivered, in September 1913 before the Senate, two speeches denouncing Victoriano Huerta as the murderer of Madero and calling for his removal. The texts were never read from the floor because the Senate itself denied them to him. He was kidnapped on October 7 and murdered in Coyoacán the following dawn.

Context of the year. The piece is from 2009 and honors the civilian arm that opposed the military coup of 1913. His murder accelerated Huerta's dissolution of Congress and radicalized the Constitutionalist side.

The reverse of the coin. The reverse of this 5-peso piece shows the portrait of Belisario Domínguez Palencia, his engraved signature, and the year 2009, per the Bank of Mexico's official catalog for the commemorative series of the Centennial of the start of the Revolution (1910-2010).

Legacy. The Belisario Domínguez Medal, the highest distinction of the Mexican Senate, has been awarded since 1953. Comitán de Domínguez, in Chiapas, adopted his surname.
