1947 Mexican 1 Peso Silver (Cuauhtémoc): Value Guide

If you inherited a 1947 Mexican 1 peso with a stern profile on the back, here is the honest answer: in worn condition it is worth roughly its silver content, not a fortune. In 2026 that puts most examples in the low double digits in USD. The exceptions are top-grade, uncirculated pieces, which sell for meaningfully more.

This is a common date, so age alone does not make it valuable. What matters is grade and silver content. Below is what yours is actually worth and how to check it.

What this coin is

The 1947 1 peso is one of the larger, silver-rich pesos that circulated in Mexico. The back (reverse) shows the profile of Cuauhtémoc, the last Aztec (Mexica) tlatoani, or ruler. The front (obverse) carries the Mexican coat of arms: an eagle perched on a cactus, gripping a serpent, with the legend ESTADOS UNIDOS MEXICANOS around the rim. It was struck at the Casa de Moneda de México, the Mexican Mint.

Quick specs:

• Metal: silver, .500 fine (50% silver, 50% other metals)
• Weight: 13.9 g
• Actual silver weight: about 7 g, or roughly 0.225 troy ounces
• Diameter: 32 mm
• Edge: reeded (grooved)
• Mintage: 61,460,000 pieces
• Catalog reference: KM# 456

The Cuauhtémoc type was struck from 1947 to 1949 at this size and fineness. It was a transition coin: the peso still held a real chunk of silver before later reforms shrank the diameter, weight, and purity.

How much is a 1947 1 peso worth?

Start with the floor. The coin holds about 0.225 troy ounces of pure silver, so its melt value is that fraction of the daily silver price. When the fineness is common, as it is with the 1947 date, silver sets the base price and grade drives everything above it.

These are ranges, not guarantees. The headdress feathers and the cheek of the profile wear first, so a coin with crisp relief in those spots is worth far more than a flat, circulated one.

Is it rare?

No. With 61,460,000 struck, the 1947 is one of the easiest dates in the series to find, alongside 1948. Millions survive. If a listing calls a common-date 1947 peso "rare" or prices it in the hundreds without a professional grade to back it up, that is a red flag. The interest in this coin comes from its silver, not scarcity.

The ones people overpay for

Sellers sometimes market any old Mexican silver peso as a treasure. For the 1947 specifically, the only versions that command real premiums are certified uncirculated examples in MS64 or higher, where the eye appeal and sharp strike justify the price. A raw, worn coin is a silver piece with a nice design, and it should be priced accordingly. Do not pay a rarity premium for a date that was minted in the tens of millions.

If you want to compare it to a Mexican silver coin that actually carries a scarcity premium, look at earlier or lower-mintage peso types before assuming yours is the valuable one.

How to check if yours is genuine

1. Weigh it. It should come in close to 13.9 g. A significant deviation is a warning sign.
2. Measure it. Diameter should be 32 mm, with a reeded edge.
3. Check the color. At .500 fine, the silver has a slightly grayish tone, not the bright white of a .720 or .900 coin. An overly white or yellowish surface can indicate a fake or a cleaned coin.
4. Inspect the strike. Genuine coins show crisp lettering and fine detail in Cuauhtémoc's headdress. Cast counterfeits look soft, grainy, or have seam marks on the edge.

If you are unsure about authenticity or grade, get it checked by a dealer or send it to NGC or PCGS for certification. Certification only makes financial sense for high-grade pieces.

Where to sell it

Common-date silver pesos sell at coin shops, silver buyers, and numismatic dealers. For a worn 1947, expect an offer built on the day's silver price plus a small margin. For an uncirculated or certified example, seek out a numismatic buyer who pays for grade, not just metal.

Compare offers before you commit. A worn coin is a bullion transaction; a graded gem is a collector transaction, and the two are priced very differently.

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 the $1, $5, $10, $25 denominations during the 1940s-50s; cupronickel starting in the 1970s; bronze-aluminum 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. 1947 corresponds to the period in which this variety was in circulation.
