1950 Mexican Silver Peso (Morelos): Value & Silver Content

If you inherited a 1950 Mexican silver peso and want the short answer: a worn one is worth a few dollars for its silver, and a sharp uncirculated example can bring 50 to 80 USD or more. This is not a rare coin. More than 3.2 million were struck, so grade and eye appeal drive the price, not scarcity.

The 1950 peso is nicknamed the Morelos peso because the reverse shows the bust of José María Morelos y Pavón, a Mexican independence leader. Collectors in Mexico also call it the Pescuezón ("thick-necked"), because the 1950 bust has a noticeably wide neck compared to Morelos pesos of later years. That single feature is the fastest way to tell a 1950 apart.

What it's actually worth in 2026

The 1950 peso (catalog reference KM-457) contains about 4 grams of pure silver, roughly 0.129 troy ounces. At current silver prices that metal is worth around 4 to 6 USD, and that is the floor: no genuine 1950 peso is worth less than its silver.

What you get above that floor depends entirely on condition:

These are collector-market ranges, not fixed prices. A raw coin sold in a mixed lot often trades near its silver value regardless of how nice it looks, because buyers of lots do not pay a premium per coin.

Is it rare?

No. The official mintage was 3,287,000 pieces, and 1950 Morelos pesos show up regularly in old circulation, dealer trays, and inherited boxes. It is a common coin. What makes a 1950 stand out is grade: worn examples are everywhere, while pieces with full original luster and sharp detail in Morelos's hair are worth chasing.

One thing that does make 1950 special: this exact type was struck in one year only. Later Morelos pesos used different silver content and design details, so the 1950 is the anchor date for anyone building a set of the type. That collector demand supports the premium on high-grade examples, but it does not make the coin rare.

Specifications (keep these to check yours)

A note on fineness: you will see the 1950 peso listed two ways online, as .720 silver and as .300 silver. This is a common point of confusion in old listings. The standard catalog for the 1950 type (KM-457) records it as .300 fine, which yields the roughly 4 grams of pure silver figure above. If a seller quotes you a much higher silver weight based on .720, verify the type and year before you pay a premium.

How to tell if yours is genuine

Counterfeits of common circulation silver are uncommon because the payoff is small, but here is how to confirm a real one:

1. Weigh it. A genuine 1950 peso weighs 13.34 grams. Use a precision scale (jewelry or kitchen scale that reads to 0.01 g). A fake in base metal will usually be off.
2. Measure it. 32 mm across, with a reeded (grooved) edge.
3. Check the details. Look for the wide-necked Morelos bust, the Mo mint mark, and the 1950 date.
4. The ring test. Real silver has a distinct high ring when tapped. Base-metal copies sound dull.

If you have several or one in exceptional condition, professional grading by NGC or PCGS confirms authenticity and grade at the same time, which is what unlocks the higher end of the value range.

Where to sell it

For a common date like this, your options depend on condition:

• Worn coins: sell to a bullion or coin dealer at close to silver melt value. Do not expect a big premium.
• High-grade or uncirculated coins: these do better with collectors than with bullion buyers. A graded example can go through online coin auctions or specialist dealers.
• A full run of Morelos pesos: worth more as a set than piece by piece.

You can compare prices and reach buyers through the Pesoteca shop directory. If you also have other old Mexican silver, it helps to know your other pieces first, since coins are usually easier to sell together. See our guides to Mexican silver coins to identify the rest of a box.

Mexican circulating 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 the $1, $5, $10, $25 denominations during the 1940s-50s; cupronickel starting in the 1970s; aluminum bronze and stainless steel in the 1980s; pieces featuring historical figures (Hidalgo, Cuauhtemoc, Juarez, Madero) in the late 1980s just before the transition to New Pesos in 1992. 1950 corresponds to the period when this variant was in circulation.
