Mexican 5 Pesos Silver 1955 (Hidalgo): Value & Price

If you inherited a large silver Mexican coin with a man's profile and the date 1955, you likely have the 5 Pesos Hidalgo. Honest answer up front: most are worth their silver content, roughly a few US dollars, in 2026. Uncirculated examples with original luster sell for more, but this is a common coin, not a rarity.

What you actually have

The 1955 Cinco Pesos ("5 Pesos") is a large silver coin struck at the Casa de Moneda de México, the Mexican Mint. It carries the bust of Miguel Hidalgo, the priest who launched Mexico's independence movement, on the reverse. Collectors call this the Hidalgo type.

Here are the exact specs, which matter for both value and authentication:

The .720 fineness is the key number. This coin is not pure silver. It contains roughly 0.42 troy ounces of actual silver, which sets a price floor at melt value. That floor is what most circulated examples trade for.

How much is the 1955 5 Pesos worth?

Value is driven almost entirely by two things: silver content and grade (condition). This is a common date, so rarity is not on your side.

• Circulated (worn, from grandma's coin jar): Worth its silver melt value, typically a few US dollars depending on the silver spot price. Nice, but not a windfall.
• Uncirculated with original mint luster (MS grades): These bring a modest premium over melt, often into the low tens of dollars. Clean surfaces and no handling marks make the difference.
• Certified high-grade (NGC or PCGS MS64 and up): Top examples can pull further above melt, but we are still talking modest money, not hundreds.

What kills value fast: cleaning. If someone polished the coin to make it shiny, that hairline scratching drops it below what an original circulated piece would bring. Never clean a silver coin.

Check the high points before you get excited. Hidalgo's hair and the raised details wear first. A coin with sharp hair detail and full luster is worth chasing. A smooth, gray, heavily handled one is a melt coin.

Is it rare? (The honest answer)

No. The 5 Pesos Hidalgo was struck across several years in the 1950s for everyday circulation, and 1955 is not a scarce date. These are the "big silver dollars" many Mexican families remember from their grandparents' wallets. Because the price of silver kept climbing, high-denomination silver circulation coins were phased out shortly after, which is why 1955 sits near the end of this run. That history is interesting, but it does not make a common coin valuable.

If you want the Mexican silver coins that actually command real money, look at earlier and scarcer types. This one is a great, affordable starting point for a US collector, not a jackpot.

How to tell if yours is genuine

Weigh it and measure it before anything else:

1. Weight: A genuine coin weighs 18.1 grams. Use a jeweler's scale. Fakes are frequently off.
2. Diameter: It should measure 36 mm. Use a caliper.
3. Edge: The rim should be reeded (grooved), not smooth.
4. Relief and color: Counterfeits often show flat, mushy detail and uneven color. Real .720 silver has a consistent tone.

Red flag: any offer priced well below the coin's silver value. That usually means the seller knows it is fake, or you are the seller being lowballed. For a firm answer, submit the coin to a grading service like NGC or PCGS, which authenticates and grades it.

Where to sell it

Since this coin's value is tied to its silver content, sell to someone who will show you the piece, confirm the weight, and pay against a transparent silver price:

• A verified coin dealer who can appraise it on the spot and pay you at or above melt.
• The Pesoteca buy-and-sell forum, where collectors trade directly.
• Compare any offer to the current silver spot price times 0.419 troy oz so you know your floor.

Avoid dumping it to the first buyer on social media. Photograph the front (anverso), back (reverso), and edge, and know your melt value going in.

If you have a full jar of these, sort them by condition first. The shiny, mark-free ones are worth listing individually. The worn ones can go as a silver lot. See our guide to Mexican silver coins to compare this piece against the ones that actually break records.

Got one sitting in a drawer? Post clear photos of both sides in the Pesoteca forum and let the community tell you if it's a plain melt coin or something worth grading.

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 processes: .720 silver in the $1, $5, $10, $25 denominations during the 1940s-50s; cupronickel from the 1970s on; aluminum bronze and stainless steel in the 1980s; pieces with figures (Hidalgo, Cuauhtémoc, Juárez, Madero) in the late 1980s just before the transition to Nuevos Pesos in 1992. 1955 corresponds to the period when this variant was in circulation.
