8 Escudos 1829 Gold Coin: Value & Prices

If you inherited an 1829 Mexican 8 Escudos, here is the short answer: it is a large gold coin worth real money. At 27 grams of 0.900 fine gold (roughly 0.78 troy ounces of pure gold), it has a bullion floor in the low four figures in USD, and genuine, well-preserved examples sell for meaningfully more to collectors.

This is not a common pocket-change coin. It is one of the first gold pieces of the newly independent Mexican Republic, and in 2026 it trades both as gold and as a historic collectible.

What you actually have

The 8 Escudos was the largest gold denomination Mexico struck in this era, the equivalent of a heavy gold trade coin. The nickname "Octaval" refers to the eight-escudo value. This particular piece belongs to the early Mexican Federal Republic (República Federal Mexicana) period, dated 1829.

Specifications, keep these exact when you check yours:

• Weight: 27 grams
• Diameter: 36.2 mm
• Metal: Gold, 0.900 fine (90% pure gold)
• Edge: diagonal reeded
• Pure gold content: about 24.3 grams, roughly 0.78 troy ounces

That gold content is the key number. Even the most worn, damaged example is worth close to its melt value, and gold prices set a hard floor under this coin that most old coins simply do not have.

What it's worth

Value on an 1829 8 Escudos comes from three things stacked together: the gold in it, its condition (grade), and demand for early Republic gold. Here is how that breaks down.

Because gold spot moves daily, we give you the honest framework rather than a fake fixed price:

• Heavily worn or damaged: close to melt value (currently around USD 2,000 to 2,400 depending on the gold price that day).
• Circulated but solid: melt plus a collector premium.
• Sharp, high-grade, or certified examples: can bring several times melt at auction, especially for scarcer mint-and-assayer combinations.

One important note on this series: mint and assayer marks matter. Early Republic 8 Escudos were struck at several mints (Mexico City, Guanajuato, Zacatecas, Durango and others), and some year-mint-assayer combinations are genuinely scarce. Two coins that look identical can be worth very different amounts because of those tiny letters. Check the conservation grade guide and note your exact mint mark before you value it.

The myth to avoid

Every old gold coin gets called "priceless" by someone. This one is valuable, but it is not a museum-only rarity worth millions. It is a real, tradeable gold coin with a known melt value and a collector premium on top. Anyone offering you a fraction of melt, or claiming it is "just old junk gold," is trying to underpay you. The floor is the gold, and the gold is not cheap.

How to tell if yours is genuine

Fake gold escudos exist, and the payoff for counterfeiters is high, so verify before you celebrate or sell.

1. Weigh it. Use a jewelry scale. It should be very close to 27 grams. A light coin is a red flag.
2. Measure it. Diameter should be 36.2 mm. Use calipers.
3. Check the metal. Real 0.900 gold has a specific density and color. Casts often look soft, greasy, or slightly off in tone.
4. Study the strike. Genuine coins show crisp engraving and a clean diagonal reeded edge. Blurry lettering, seams, or a filed edge point to a fake.
5. Get it certified. For a coin in this value range, professional grading (NGC or PCGS) is worth it. Certification confirms authenticity, locks in a grade, and makes it far easier to sell at full value.

Be suspicious of any offer well below the gold value. If a coin is real, no serious buyer offers below melt.

Where to sell it

Because this is a precious-metal coin, sell where the price is transparent and the buyer will show you the weight and let you verify before money changes hands.

• A verified numismatic dealer from the Pesoteca shop directory. Search by city, get an on-the-spot appraisal, and avoid middleman markups.
• The Pesoteca buy-and-sell forum, where collectors trade directly and know what early Republic gold is worth.

Before you sell: photograph the front, back, and edge in good light, confirm the mint mark and date, and check the current gold price so you know your floor. Do not dump it to the first Facebook buyer. A coin this size deserves a real appraisal.

Eight escudos eight-real República Mexicana, 1829, Mexico mint. Year of the Spanish invasion by Isidro Barradas in July: 2,700 soldiers landed at Tampico attempting to reconquer Mexico for Ferdinand VII. They were defeated in September by Antonio Lopez de Santa Anna and Manuel Mier y Teran at the battle of Pueblo Viejo. It was the last Spanish military attempt against Mexican independence. Vicente Guerrero assumed the presidency on April 1 and held it until the coup by Anastasio Bustamante in December. It was the year of the definitive abolition of slavery in Mexico, decreed by Guerrero on September 15. The ounce weighs 27.06 grams with .875 fineness. Krause KM#383.9 holds for 1829. The assayer's initial continues in the reverse field. Pieces of this year are collectible for their multiple historical context: a defeated Spanish invasion and the definitive abolition of slavery. It is a coin that simultaneously documents the military closing of the monarchist threat and the most important civil milestone of the first republican decade.
