1947 Mexico 2½ Pesos Hidalgo Gold Coin: Value & Prices

If you inherited a small yellow-gold Mexican coin marked "Dos y Medio Pesos" with the year 1947, here's the fast answer: it's real gold, and its value is driven mostly by its metal content. In 2026, a typical circulated example is worth roughly 130 to 180 USD, tracking the gold price. It's not a rare date, so don't expect a fortune, but it's never junk either.

The 1947 2½ Pesos Hidalgo is one of the smallest gold coins Mexico produced for general use. It contains about 0.0603 troy ounces (1.88 grams) of pure gold, which sets a hard floor under its value: it can never be worth less than the gold inside it, no matter how worn it is.

What it's actually worth in 2026

Because this is a bullion-driven coin, the melt value moves with the daily gold price. On top of melt, collectors pay a modest premium for sharp, well-preserved pieces, especially those still in original Banco de México packaging.

These figures assume gold in a normal trading range. When gold spikes, all of these numbers rise with it. The safest way to check current melt is to multiply 0.0603 by the day's gold spot price in USD.

Why this coin is not "worth thousands"

A lot of online sellers hype old Mexican gold as rare treasure. This one isn't rare. The 2½ Pesos Hidalgo was struck across many years as part of Mexico's Hidalgo gold series, and it survives in large numbers because people saved gold coins rather than spending them. Value here comes from the metal and the grade, not from scarcity. If someone offers you far above the ranges above, ask why, and if someone offers far below melt, walk away.

Coin specifications (verify yours)

Use a jewelry scale and a caliper to confirm these exact numbers. Fakes almost always miss on weight or diameter.

This piece belongs to the pre-1992 modern Mexican coinage era, part of the monetary reform gold series first issued in 1905.

How to tell if yours is genuine

1. Weigh it. It must be very close to 2.09 grams. Gold is dense, so a fake in base metal usually feels too light for its size.
2. Measure it. The diameter should be 15 mm. Off-size is a red flag.
3. Check the detail. Genuine strikes show crisp relief on Hidalgo's portrait and the eagle. Flat, mushy, or grainy detail suggests a cast copy.
4. Color. 0.900 gold has a warm, slightly rosy tone from the copper alloy, uniform across the surface. Patchy or brassy color is suspicious.
5. Price sanity check. Any offer well below the gold melt value is almost always a scam or a counterfeit.

If you want certainty, have it authenticated. Compare your measurements against the specs above and against our Mexican coin condition grading guide.

Where to sell it

Since this is a precious-metal coin, sell only where you can see the price against the current gold spot:

• A verified coin dealer from the Pesoteca shop directory will weigh and appraise it on the spot.
• The Pesoteca buy-and-sell forum connects you directly with collectors, often the better route for uncirculated or packaged examples.

Photograph the obverse, reverse, and edge in good light before you list it. Don't dump it to the first offer on social media, and never mail a gold coin to a buyer you can't verify.

2.5 peso gold Hidalgo, 1947, Mexico mint, Krause KM#463. A low intermediate denomination of the gold standard inherited from Limantour's Monetary Reform of 1905. It officially weighs 2.083 grams at .900 fineness, with a pure gold content of 1.875 grams. This year saw an authorized restrike of the 2.5 peso Hidalgo as part of Bank of Mexico policy. Under the presidency of Miguel Alemán Valdés in his first year of government. That year the creation of the Federal Electricity Commission was decreed as a state monopoly, a founding milestone of the modern Mexican energy sector. The obverse shows the bust of Miguel Hidalgo in left profile with the legend 2 1/2 PESOS. The reverse bears the Mexican eagle with the legend ESTADOS UNIDOS MEXICANOS. Produced by mill (milled) with a round planchet. Krause KM#463 groups the production of the 2.5 peso gold Hidalgo with authorized restrikes on various dates up to the 1970s. 1947 restrike pieces are collectible for their metal content value and for documenting the gold policy at the start of the Alemán regime, one of the most transformative of post-revolutionary Mexico.
