Mexican 50 Centavos 2004: Value & How to Sell

If you found a 2004 Mexican 50 centavos coin in a jar or an inherited box, here is the honest answer: in circulated condition it is worth only its face value, a few cents in US terms. Uncirculated examples pulled from original mint packaging trade for a small premium, usually 1 to 3 dollars. This is a modern circulating coin, not a rare piece.

What this coin actually is

The 50 centavos dated 2004 is part of Mexico's aluminum-bronze series, a low-denomination coin used in everyday change. "Centavos" are the Mexican equivalent of cents, so 50 centavos is half a peso. It was struck by the Casa de Moneda de México (the Mexican Mint), the oldest mint in the Americas.

Here are the exact specifications, useful for confirming you have the right coin and for spotting fakes:

Feature	Detail
Denomination	50 centavos
Year	2004
Metal	Aluminum-bronze
Weight	4.39 grams
Diameter	22 mm
Edge	Smooth (plain)
Obverse	Mexican National Coat of Arms with legend "ESTADOS UNIDOS MEXICANOS"
Reverse	Denomination design cataloged by Banxico

The obverse (front) shows the Mexican eagle coat of arms, the standard national emblem on Mexican coinage. The reverse (back) carries the value. It belongs to Mexico's modern "Nuevos Pesos" era of coinage.

How much is it worth in 2026?

Most people who inherit a handful of these expect a hidden fortune. The reality is straightforward. This is a common circulating coin with a high mintage, and no single date in the series is scarce enough to command real money in worn condition.

Condition	Approximate value (USD)
Circulated (worn)	Face value only, a few cents
Uncirculated	1 to 3 dollars
Sealed mint packaging (blister)	Small premium over uncirculated

Value comes down to condition. A coin that has been in circulation, with scratches and wear, is worth its face value. A crisp, uncirculated example, especially one still in its original Banxico mint blister, carries a modest premium among collectors who want a full date set.

What could make yours worth more

Two things can push a common coin above face value:

1. Top-grade condition. A certified uncirculated example (graded by a service like NGC or PCGS) attracts set collectors. Still, for a coin this common, certification often costs more than the coin is worth.
2. Genuine mint errors. Off-center strikes, die rotations, and double strikes can multiply value if they are verified factory errors. Be careful here: most "errors" shared online are post-mint damage, corrosion, or dings, not real striking errors. A dented or acid-stained coin is just damaged, not valuable.

If you think you have a genuine error, post clear photos to the Pesoteca forum so the community can check it before you get your hopes up.

How to tell if it's genuine

Counterfeits of a 50 centavos coin are rare because there is no profit in faking a piece worth pennies. Still, if you want to confirm:

• Weigh it on a jewelry scale. It should read close to 4.39 grams.
• Measure the diameter. It should be 22 mm.
• Check the edge, which should be smooth with no reeding.

Fakes typically show wrong weight, wrong diameter, flat detail, or uneven coloring.

Where to sell it

Because the value is low, your best move is to sell a group of coins together rather than one at a time. Options:

• A verified numismatic shop from the Pesoteca directory, which can appraise your coins on the spot.
• The Pesoteca buy-and-sell forum, where you deal directly with collectors.

Photograph the obverse, reverse, and edge before you sell, and compare against the price ranges above so you know what to expect. If it is only circulated, it may simply be spendable change.

Context of the fifty-centavo piece of the year 2004

This fifty-centavo coin (KM#549) was struck by the Mexican Mint in 2004, under the presidency of Vicente Fox Quesada. It is part of the circulating family in bronze and aluminum alloy with nickel that Banxico issued between 1992 and 2009, at 22 mm in diameter and 3.10 g in weight.

The year in Mexico. It is the year the scandal of the videos of Rene Bejarano and Gustavo Ponce broke, shaking the city administration of Andrés Manuel López Obrador. It was also a year of inflationary pressure from the rise in the international price of oil. That year, according to INEGI's INPC, annual inflation closed at 5.19% and the Bank of Mexico's FIX exchange rate closed the year at 11.15 pesos per dollar.

How it circulated. In 2004 these pieces circulated in a country with inflation again above 5%. The prices of basic foods rose sharply. These coins were still common change on urban transit, though their everyday purchasing power fell relative to the previous year.

Numismatic note. The 2004 die corresponds to an abundant minting. The minimal relief variations at the corners of the reverse are attributed to natural wear of the dies. The obverse design is Banxico's official National Coat of Arms and the reverse shows the face value alongside the year of minting. From year to year the design remains identical and only the engraved date changes, so the visible difference is minimal. Internal die variations, when they exist, are documented in the Bank of Mexico's catalog.
