1 Nuevo Peso 1992 (N1): Value & What It's Really Worth

If you inherited or found a 1992 Mexican peso marked "N1," here's the honest answer: in circulated condition it's worth about its face value, roughly the equivalent of 5 to 10 US cents. A crisp uncirculated example runs closer to 1 US dollar. It's not silver, not gold, and not rare. Mexico struck around 144 million of them in 1992 alone.

That said, this coin has a story worth knowing, and there's one variety detail (the edge) that's worth checking before you assume yours is ordinary.

What this coin actually is

The 1992 "N1" is the first-year issue of Mexico's Nuevos Pesos (New Pesos), catalogued as KM 550. In 1993 Mexico ran a currency reform that lopped three zeros off the old, inflation-battered peso: 1 new peso equaled 1,000 old pesos. Coins were struck dated 1992 so they'd be ready when the reform took effect on January 1, 1993.

The N stamped before the 1 stands for Nuevo (new). That's why the coin reads "N1" instead of just "1 Peso." Mexico used the N symbol until 1996, then dropped it and went back to plain "peso." So if you have an N1 coin, you're holding a piece from that specific 1992 to 1996 transition window.

Specifications (keep these to verify authenticity)

• Composition: bimetallic. Golden center in aluminum bronze, silver-colored outer ring in stainless steel.
• Weight: 3.95 g
• Diameter: 21 mm
• Edge: plain (not reeded) on the standard KM 550 issue
• Mint mark: Mo (Casa de Moneda de México, Mexico City)
• Obverse: the Mexican national coat of arms (the eagle and serpent)
• Reverse: the N1 denomination with the Mo mint mark

Because it's bimetallic steel and bronze, there is no precious metal value. It won't have a melt floor the way a silver coin does.

What it's worth in 2026

This is one of the most common modern Mexican coins in existence, so don't expect much unless you have an exceptional piece.

Grade	Approx. value (USD)
Circulated (worn)	Around face value, 5 to 10 cents
Uncirculated (UNC), well preserved	Roughly 0.50 to 1 USD
Certified top grade (NGC/PCGS MS66+)	Modest premium, still low

Figures follow catalog references such as Numista. The value driver here is condition, not the date. A worn 1992 is worth pocket change. A bright, mark-free uncirculated example of the first-year issue is the only version that carries a small premium, because collectors of modern circulation coins like to own the debut year of a series.

Is it rare? No.

Mexico struck about 144 million of these in 1992 with the Mo mint mark, and the series continued through 1993, 1994, and 1995 with equally high mintages. Its rarity index on Numista is very low. If a listing tells you this coin is "rare" or "worth thousands," walk away. Only certified high grades command anything above a dollar or two.

The edge is worth checking

Here's the one detail that matters. The standard 1992 N1 (KM 550) has a plain edge, according to Numista and world coin catalogs. If your coin has a reeded (ridged) edge, that does not match the standard issue, and it's worth a closer look. Most of the time this just means confusion with a different denomination, but it's the kind of variance that's worth verifying against the specs above.

How to tell if yours is genuine

Fakes of a coin worth pocket change are rare, but you can confirm authenticity in seconds:

1. Weigh it. Should be 3.95 g. A cheap kitchen scale that reads to 0.1 g works.
2. Measure it. Should be 21 mm across.
3. Check the build. Golden aluminum-bronze center, silver-colored stainless steel ring.
4. Check the edge. Plain, not reeded, on the standard issue.
5. Confirm the marks. N1 on the reverse with the Mo mint mark, national coat of arms on the obverse.

If the weight or diameter is well off those numbers, be suspicious.

Where to sell it

Because it's so common, this coin trades in bulk lots, in change, or through specialized dealers. Selling a single circulated piece rarely makes financial sense given the value. If you have a genuinely uncirculated first-year example and want to move it, or you want to buy one to complete a set, use a trusted seller.

When Banxico dropped the N$ prefix from the peso starting in 1996, circulating pieces kept the same physical format as their Nuevos Pesos equivalents from the decree of June 22, 1992. This 1-peso stainless steel coin struck in 1992 is part of that continuity: same technical specifications, same base design with the National Coat of Arms on the obverse, only the nominal value visible on the reverse changed. That's why, when you line up the dates, you see long sequences with very little variation.

For the Mexican collector building a collection by year, these pieces are the ones that fill the basic gaps before hunting the rare commemorative versions. Banxico documents mintages in its Monetary Circular CM10 from the year 2000 on, so for 1992 it's possible to verify the exact mintage against that source. Pesoteca catalogs each year as a distinct physical piece in the PSM System family C, following our convention of one ID per collectible piece, not per shared design.
