1 Peso 1982 (Morelos, Cupronickel): Value & Prices

If you inherited a big silver-colored Mexican coin dated 1982 with a man's profile on it, here is the honest answer: a worn 1982 one peso is worth roughly 12 US cents, barely above face novelty value. It is one of the most common Mexican coins ever struck. A pristine uncirculated example, especially the open-8 variety, is the only version that brings real money, up to around 20 USD.

What this coin actually is

This is the 1 Peso Morelos in cupronickel, dated 1982. The man on the reverse is José María Morelos y Pavón, a hero of Mexican independence, shown facing left. The front (obverse) carries the Mexican coat of arms with the legend ESTADOS UNIDOS MEXICANOS. The small letters Mo are the mint mark of the Casa de Moneda de México (the Mexican Mint), not a rarity indicator.

It is a large coin for its denomination, which is why people who find one assume it must be valuable. It is not, in most cases. Mexico struck it during the high-inflation years before the 1993 currency reform (the Nuevo Peso), so these coins were pumped out by the hundreds of millions.

Specifications (exact):

Is it silver? No

This is a common first question, and the answer kills the fortune fantasy: there is no silver or precious metal in this coin. It is cupronickel, 75% copper and 25% nickel. Its melt value is negligible, so any worth it has is purely numismatic, driven entirely by condition. If you want actual Mexican silver, that is a different set of coins.

What the 1982 one peso is worth

Condition is the whole game here, because nearly all of these coins spent years rattling around in pockets.

A worn 1982 peso runs around 12 pesos in Mexico, roughly 60 US cents. It is one of the most common coins in the entire Morelos type. Only a truly uncirculated piece with full detail and original luster is worth setting aside.

The open-8 vs closed-8 variety

The one detail worth checking on your coin is the shape of the 8 in the date 1982. Some examples have the 8 more open at the base (the open-8), others have it closed. The open-8 in high grade (MS63 uncirculated) is the version that brings the most, up to about 20 USD. In worn condition, the variety barely moves the price.

The one you should not confuse it with

Here is where value actually hides: the 1983 Morelos 1 peso is genuinely scarce and worth considerably more than the 1982. If you have a stack of these, sort out any 1983 dates first, they are the ones that matter. The 1982 is abundant; the 1983 is the year collectors chase.

Why it is not rare

Mexico struck about 235 million closed-8 pesos in 1982 alone, plus the open-8 variety. Across the full Morelos cupronickel type (1970 to 1983), more than 3.3 billion pieces were produced. A circulated 1982 is one of the easiest Mexican coins to find, which is exactly why the worn ones are worth cents.

How to check what yours is worth

1. Check the date first. 1982 is common; 1983 is scarce and worth more.
2. Grade the condition. Look for wear on Morelos's cheek and hair. Full sharp detail plus original mint shine means it may be uncirculated and worth keeping.
3. Check the 8 in the date. Open-8 in high grade is the premium version.
4. Confirm it is genuine. These coins are too low in value to be counterfeited, so authenticity is rarely a concern. Match the specs: 9.0 g, 28.86 mm, reeded edge, cupronickel color (no silver tone).

Where to sell it

Because it is so common, you will find plenty of dealers who handle it. Browse the Pesoteca store directory to locate a buyer. Be realistic: a worn 1982 is a pocket-change coin. Only an uncirculated example, or the open-8 variety in top grade, is worth pricing individually. If you have a whole box of mixed Mexican coins, pull the 1983 dates and any silver coins aside first, those are where the money is.

Mexican circulating peso coins from the second half of the 20th century were struck in alloys that changed according to the cost of metals and inflationary pressures: .720 silver in the $1, $5, $10, and $25 denominations 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. 1982 corresponds to the period when this variant was in circulation.
