1990 Mexican 10 Pesos Hidalgo (Steel): What It's Worth

If you inherited or found a 1990 Mexican 10 Pesos with Miguel Hidalgo on it, here is the honest answer: in circulated condition it is worth about 1 US dollar, or roughly 18 to 20 Mexican pesos. It is one of the most common modern Mexican coins ever struck. Around 1.45 billion of the steel type were minted. The listings claiming 35,000 or even 100,000 pesos are seller fantasy, not market value.

Let's cover what it actually is, what drives its (small) value, and how to spot the fake "error coin" claims in 2026.

What this coin is

The 1990 10 Pesos is the stainless-steel version of the Hidalgo 10 Pesos, minted from 1985 to 1990. "Hidalgo" refers to Miguel Hidalgo, the priest who launched Mexico's independence movement, whose portrait appears on the coin. Because the coin is steel, it is magnetic, an easy way to tell it apart from the older, larger, non-magnetic 10 Pesos types.

This is also the last 10 Pesos denomination before Mexico's 1993 monetary reform introduced the Nuevo Peso (New Peso) and cut three zeros from the currency. The coin was demonetized in 1995. So it does close out an era, but "closing an era" and "being rare" are two different things. This one is abundant.

What it's actually worth

In plain terms: a worn one is worth about a dollar. A crisp uncirculated example with sharp detail on Hidalgo's portrait and the original steel shine is worth a bit more, but this is still a low-value coin. The only thing that separates a good example from a common one is condition, not the date.

Collectors do buy these to complete a year-by-year set of the steel 10 Pesos, and 1990 (as the final year of the type) is a natural stopping point for that set. That collector demand is real but modest. It does not turn a common coin into a treasure.

The "worth 100,000 pesos" myth

You will find online listings offering the 1990 10 Pesos for 35,000 pesos, and at least one at 103,250 pesos, all claiming a valuable minting error. Look closer and the photos never show a verifiable error, and there are no completed sales at those prices. Anyone can list a coin for any number. That does not make it the market value. It is a listing tactic, not a sale.

Genuine mint errors (clear doubled dies, wrong planchet, dramatic off-center strikes) are verified coin by coin and are genuinely scarce. A normal 1990 coin does not have them by default. If your coin looks like every other 1990 10 Pesos, it is worth about a dollar, full stop.

How to tell if yours is genuine

This is a common, low-value coin, so counterfeits are unlikely, but here is how to confirm it:

• Weight: 3.82 g
• Diameter: 19 mm
• Magnetism: it should stick to a magnet (it's steel)
• Reverse: value shown vertically, a Braille numeral (added so the coin can be identified by touch), the year, and the Mo mint mark
• Obverse: Hidalgo's bust with his name at the base

If the weight or size is off, be suspicious. If everything checks out and there is no obvious error, you have a standard 1990 issue.

Where to buy or sell it

Because the value is so low, these usually change hands in bulk lots of circulated coins rather than one at a time. If you want to buy a nice uncirculated example or sell yours, check the Pesoteca store directory for physical and online dealers. Be careful with resale platforms, where inflated "error coin" prices are common. For context on how this fits into the broader series, see our guides to Mexican coins and their value and how to identify real mint errors.

The circulating Mexican peso coins of the second half of the 20th century were struck in alloys that changed according to the cost of metals and inflationary processes: .720 silver in denominations $1, $5, $10, $25 during the 1940s-50s; cupronickel starting in the 1970s; aluminum bronze and stainless steel in the 1980s; pieces with historical figures (Hidalgo, Cuauhtémoc, Juárez, Madero) in the late 1980s just before the transition to Nuevos Pesos in 1992. 1990 corresponds to the period when this variant was in circulation. Miguel Hidalgo y Costilla, father of Mexican Independence, appears on circulating denominations starting in the mid-20th century.
