1915 Oaxaca 5 Pesos Silver: Value & How to Sell

If you inherited a 1915 5 Pesos silver coin marked "Estado Libre y Soberano de Oaxaca," you have a genuine piece of Mexican Revolution history, not just a common old coin. This is a silver coin (16.2 grams) struck by the state of Oaxaca while the country was at war, and condition drives its value from modest to serious money for collectors.

What it is worth right now, in 2026

Start with the floor: this coin contains 16.2 grams of silver, so it can never fall below its melt value. But that is not the whole story here. Revolutionary state issues like the Oaxaca 5 Pesos are collected as historical artifacts, so genuine examples in decent shape trade well above bullion.

As a practical range, a worn but authentic 1915 Oaxaca 5 Pesos typically sells from around 25 to 60 US dollars, while sharp, problem-free examples with good detail can reach several hundred dollars at auction. Certified high-grade pieces (graded by NGC or PCGS) sit at the top of that range. Because the Oaxaca revolutionary coinage was struck under crude wartime conditions, quality varies enormously, and that variation is exactly what separates a 30-dollar coin from a 300-dollar coin.

Why this coin has value beyond the silver

During the Mexican Revolution, the central government lost control of large parts of the country, and several factions and states minted their own money to pay troops and keep commerce moving. Oaxaca was one of them. These "revolutionary" issues were produced in limited quantities, under improvised conditions, and many were later melted down. That combination of short production, historical importance, and survival rate is what gives the Oaxaca 5 Pesos collector demand.

The 1915 date is important: it places the coin squarely in the peak of the revolutionary coinage period. Collectors of Mexican Revolution money actively seek Oaxaca pieces to complete a set, which supports prices even for circulated examples.

The myth: "it's a hundred years old so it must be worth thousands"

Age alone does not make a coin valuable. Millions of old Mexican coins are worth a few dollars. What lifts the Oaxaca 5 Pesos above that is a specific mix: real silver content, a limited revolutionary mintage, and genuine collector demand. A common, heavily worn example is a nice historical keepsake worth tens of dollars, not thousands. Do not expect a retirement fund from a single circulated coin.

Be skeptical of anyone online claiming any 1915 Oaxaca coin is worth a fortune. The record-level prices go to certified, high-grade pieces, and even those land in the hundreds, not the tens of thousands.

How to check what yours is actually worth

1. Weigh and measure it. Use a jewelry scale and a caliper. It should weigh 16.2 g and measure 31.44 mm. Wrong numbers usually mean a counterfeit or a cast copy.
2. Check the edge. The genuine coin has a reeded (grooved) edge. A smooth or mushy edge is a red flag.
3. Grade the condition. Sharp lettering, clear design, and minimal wear mean more money. Corrosion, scratches, and heavy wear pull the value down toward melt.
4. Photograph both sides and the edge in good light before asking for an appraisal or selling.
5. Consider certification. If your coin looks high-grade and problem-free, submitting it to NGC or PCGS can significantly increase what a buyer will pay, because it removes doubt about authenticity and grade.

About "error" coins

Genuine mint errors (off-center strikes, die rotation, doubled dies) can multiply a coin's value, but most "errors" people spot on social media are post-mint damage: dings, corrosion, or cleaning marks. That is especially true for revolutionary coins, which were crudely made to begin with, so a rough strike is normal, not a rare error. If you think you have a true error, get a second opinion before you count on any premium.

Where to sell it safely

For the best result, take it to a verified numismatic dealer who will weigh it and appraise it in front of you, or list it among collectors on the Pesoteca buy-and-sell forum. Because this is a precious-metal coin, only deal with someone who lets you see and weigh the piece first. Avoid dumping it on the first offer you get on social media, and be suspicious of any offer far below the coin's silver value.
