1739 Mexico 8 Escudos Gold (Felipe V): Value & How to Sell

If you inherited or found a 1739 Mexico 8 escudos gold coin, you are holding a genuine piece of colonial gold. The short answer: even a worn, damaged example is worth well over 1,800 USD in 2026 just for its gold content, and a certified, well-preserved coin can sell for several thousand dollars. This is not a common pocket coin. It is a heavy gold piece struck at the Mexico City Mint under Spanish colonial rule.

But before you get excited, know this: the market is full of Chinese-made fakes of exactly this type of coin, because the gold value alone makes counterfeiting profitable. The weight is your first and best defense, and we explain that below.

What you actually have

This is an 8 escudos coin, the largest gold denomination of Spain's colonial coinage. Collectors and old texts sometimes call these "doubloons." Yours was struck in 1739 during the first reign of King Felipe V of the Bourbon dynasty, at the Casa de Moneda in Mexico City (then part of the Viceroyalty of New Spain).

The hard specs, which you should verify on your own coin:

• Metal: gold, .875 fine (21 karat)
• Weight: 27.05 grams
• Diameter: 37 mm
• Edge: diagonally reeded
• Mint: Mexico City
• Assayer mark: MF

At .875 fineness and 27.05 grams, the coin contains roughly 23.7 grams of pure gold, close to 0.76 troy ounces. That gives it a hard floor tied to the international gold price. That floor alone is worth well over 1,800 USD at current gold levels, and it moves with the gold market.

What drives the price above melt

Gold content is the floor, not the ceiling. Three things push a colonial 8 escudos above its melt value:

1. Authenticity. A confirmed genuine coin is worth far more than a suspicious one. Certification matters here more than almost any other factor.
2. Condition (grade). A heavily worn, holed, or ex-jewelry example trades close to melt. A sharp, problem-free coin commands a real numismatic premium.
3. Type and date desirability. Early Bourbon Mexico City gold has a steady collector base. This is a recognized, collectible series, not an obscure token.

Because colonial gold from this era was struck by hand and shipped worldwide, condition varies enormously. That is exactly why a certified grade changes the number so much.

Value ranges you can expect

These are honest ranges, not fixed prices. The exact number depends on the specific coin in hand, and the only way to nail it down is authentication and grading. Colonial gold this old rarely trades without either damage questions or authenticity questions, so a clean, certified example carries a real premium.

The counterfeit problem (read this before you buy or sell)

Modern fakes of 8 escudos gold coins are common. Most come from China and cheat on the gold content, which means they almost never hit the correct weight. Your coin should weigh 27.05 grams and measure 37 mm. If your piece is off on weight, especially light, treat it as suspect.

Quick checks you can do at home:

• Weigh it on a jeweler's scale (0.01 g precision). It should read very close to 27.05 g.
• Measure the diameter (37 mm) and check for the diagonally reeded edge.
• Gold does not stick to a magnet. If it responds to a magnet, it is not solid gold.

None of these home tests are proof. For a coin worth this much, the definitive answer is certification by NGC or PCGS, the two major US grading services. They authenticate and grade the coin and seal it in a tamper-evident holder. If you plan to buy or sell above a few thousand dollars, that certification pays for itself.

How to check what yours is worth

1. Weigh and measure it. Confirm 27.05 g and 37 mm first. This screens out the obvious fakes.
2. Photograph both sides and the edge in good light. Serious buyers and appraisers will ask for exactly these images.
3. Get it authenticated. For a coin in this value bracket, submit it to NGC or PCGS, or take it to a reputable dealer who will authenticate before quoting.
4. Do not clean it. Cleaning colonial gold reduces its value. Leave it exactly as you found it.

Where to sell it

Because this is a precious-metal coin, you always have a buyer at some price, but where you sell decides how much of the premium you keep. Options that make sense:

• Established coin dealers and auction houses that handle world and colonial gold. They will authenticate, and reputable ones pay closer to full market for graded material.
• Verified numismatic shops rather than a generic pawn or scrap-gold buyer, who will likely offer melt only.
• Collector communities for private sales, where you can reach buyers who value the coin as more than metal.

Whatever route you take, sell only after you know whether the coin is genuine and roughly what grade it is. Selling an unauthenticated colonial 8 escudos to the first offer is how people leave thousands of dollars on the table, or unknowingly pass off a fake and create a dispute.

This coin belongs to the Colonial Escudos gold series, from the Colonial / Viceroyalty era. You can also compare other Mexican 8 escudos and other coins dated 1739.

Have one of these and not sure if it is real? Post clear photos of both sides and the edge, plus the exact weight, in the Pesoteca forum and let collectors help you check it before you sell.

Eight escudos, Felipe V second period, 1739, Mexico City mint, assayer MF, Krause KM#148. Final year of the great matlazahuatl epidemic that devastated New Spain from 1736. It is also the year of the Royal Decree that created the Viceroyalty of New Granada as a territory separate from Peru, which reorganized the administrative map of the Americas. In Mexico, Vizarron y Eguiarreta continued as interim viceroy, a dual role held with the archbishop's miter. The onza weighs 27.06 grams with 0.916 fineness. Milled production had already been running for seven years at the Mexico City Mint with standardized weight and diameter. The pillar reverse remained without significant changes from the start of the series in 1732: crowned Pillars of Hercules, banners with PLVS VLTRA, crowned royal shield on the obverse. The MF signature is the shared mark of two assayers of the capital's workshop.
