1915 Aguascalientes 20 Centavos Copper Coin: Value & Guide

If you inherited or found a 1915 Aguascalientes 20 Centavos copper coin, here is the honest answer: most examples are worth a few dollars to a few tens of dollars in 2026, not a fortune. It is a genuine piece of Mexican Revolution history, but survivors are common enough that condition, not age, drives the price.

What this coin actually is

This is a revolutionary-era emergency coin. Between roughly 1913 and 1917, Mexico had no single national currency. Different states and factions struck their own money to keep local economies moving. The state of Aguascalientes (a small state in central Mexico) issued this 20 Centavos in copper in 1915.

"Centavos" are the fractional coins of the Mexican peso, the equivalent of cents. So this was low-value pocket change at the time, struck in cheap copper rather than silver or gold.

Specifications (verify yours against these)

• Metal: Copper
• Weight: 10.86 g
• Diameter: 30 mm
• Edge: Reeded (grooved)
• Mint: Aguascalientes
• Year: 1915
• Catalog reference: listed as 21 in specialized catalogs

Because it is copper and not a precious metal, this coin has no bullion floor. Its entire value is collector value, which means grade is everything.

What it is worth

Revolutionary state issues from Aguascalientes are collected, but the 1915 copper 20 Centavos is not among the rare, headline-grabbing pieces. Here is a realistic breakdown by condition.

Coin	Year	Condition	Approx. value (USD)
Aguascalientes 20 Centavos (copper)	1915	Worn / circulated	3 to 10 dollars
Aguascalientes 20 Centavos (copper)	1915	Nice detail (VF-XF)	15 to 40 dollars
Aguascalientes 20 Centavos (copper)	1915	Uncirculated / certified high grade	60 to 150+ dollars

The higher figures apply only to problem-free coins with strong strike and original surfaces, ideally graded by a service like NGC or PCGS. Copper is unforgiving: cleaning, corrosion, and dark spots hurt value fast. A once-nice coin that someone polished can lose most of its premium.

These are honest ranges based on how comparable revolutionary state copper trades. If yours is exceptional or shows a verified error, it can exceed them.

The "it must be worth thousands because it's old and from the Revolution" myth

Age and a dramatic backstory do not equal money. Millions of revolutionary-era coins survive, and copper fractional pieces are among the most common. The coins from this period that command real money (hundreds to thousands of dollars) are specific gold and silver issues from states like Oaxaca or rare die varieties, not everyday copper centavos. If a listing tells you this coin is a hidden four-figure treasure in average condition, that is marketing, not the market.

Are there valuable errors?

Genuine mint errors (off-center strikes, die rotation, double strikes, recognized varieties) can multiply the value if they are real and verifiable. The catch: most "errors" people post online are post-mint damage, corrosion, or wear, not factory mistakes. Revolutionary coins were struck under crude conditions, so weak or uneven strikes are normal and not premium errors. If you think you have a true error, get a second opinion before you count on a payday.

How to tell if yours is genuine

Counterfeits of scarcer revolutionary issues exist, so a quick check is worth it.

1. Weigh it. Use a jewelry scale. It should sit near 10.86 g. Way off means trouble.
2. Measure it. Diameter should be about 30 mm.
3. Check the edge. It should be reeded (grooved). A plain edge is a red flag.
4. Look at the relief. Cast fakes tend to look flat, soft, or grainy, sometimes with a visible seam on the edge.

Minor variation is normal for a hand-struck 1915 coin, but wrong weight or wrong diameter is the fastest way to catch a fake.

Where to sell it

• For a certified value, submit it to NGC or PCGS. A graded coin sells for more and removes doubt about authenticity.
• List it on the Pesoteca buy-and-sell forum, where collectors of Mexican coins actually look for these.
• Compare with recent sales on our guide to Mexican Revolution coins before you accept an offer.
• If you have a full box of inherited coins, read how to value inherited Mexican coins first so you do not sell the good ones for scrap.

Photograph the obverse (front), reverse (back), and edge in good light before you sell, and never dump it on the first social-media offer.
