8 Escudos Fernando VI 1751 Gold Coin: Value & How to Sell

If you inherited or found an 8 Escudos coin dated 1751 with Fernando VI on it, you own a genuine piece of colonial gold. This is not a common coin. At minimum it is worth its gold content, roughly 0.68 troy ounces of pure gold, and in collectible grades authentic examples sell for thousands of dollars at major auctions.

The short answer: value ranges from around USD 1,500 for a worn, damaged, or lower-quality example (mostly melt value) up to USD 10,000 or more for a well-preserved, certified specimen. The exact figure depends on grade, eye appeal, and authenticity. Below we break down what drives the number and how to check your specific coin.

What this coin actually is

The 8 Escudos was the largest gold denomination struck in the Spanish colonial system. This one comes from the Mexico City Mint (Casa de Moneda de México), then part of the Viceroyalty of New Spain under the Spanish Crown. It carries the portrait and name of Fernando VI, king of Spain from the Bourbon dynasty, and is dated 1751.

Collectors of this era often call the large gold 8 Escudos an "onza" (ounce), because its weight is close to a troy ounce. Here are the hard specs, which matter for both value and authenticity:

Pure gold content works out to about 23.66 g, or roughly 0.76 troy ounces. That is the floor of the coin's value. Even the most beaten-up genuine example is worth its metal, which is why these are never "worth a few dollars."

What it is worth in USD

Colonial 8 Escudos gold pieces trade on two separate value drivers: gold content and collector rarity. For 1751-dated Mexico City pieces, both matter.

• Melt / bullion floor: roughly USD 1,500 to 1,800 depending on the gold spot price. This is what a low-grade, holed, or damaged example is worth as metal.
• Circulated but sound (VF to XF): typically USD 2,500 to 5,000 for an original, problem-free coin with clear detail.
• High grade / certified (AU to Mint State): USD 6,000 to 12,000 or more. Choice examples of early Fernando VI gold from Mexico City are genuinely scarce, and top-graded pieces have brought five figures at Heritage and Stack's Bowers sales.

We give ranges rather than one exact figure on purpose. Two coins with the same date can differ in price by a factor of five based on grade and eye appeal alone. A precise number requires seeing the coin, ideally in a certified holder from NGC or PCGS.

Is it rare?

Early Bourbon gold from the Mexico City Mint survives in modest numbers, and 1751 is squarely in the scarce range for the denomination. Exact mintage figures for individual colonial years are not reliably documented, so "rarity" here is measured by how many survive and appear at auction, not by a published production number. Certified populations from NGC and PCGS give the best real-world sense of scarcity, and for early Fernando VI 8 Escudos those numbers are low.

Within a single date there can be die varieties (minor differences in lettering or design), which specialists and grading services distinguish. For most owners, though, the coin's value is set by grade and authenticity, not by hunting a micro-variety.

The myth vs. reality

A common belief is that any coin this old must be worth a fortune. Age alone does not do it. What makes this piece valuable is the combination of real gold content and genuine scarcity of well-preserved survivors. A worn, cleaned, or damaged example is worth close to melt, not a museum price.

The opposite myth is just as costly: assuming yours is "just old money" and selling it for scrap. That is how people give away thousands of dollars. If your coin is genuine, it is never worth only its face-era value.

How to tell if yours is genuine

Counterfeits of colonial gold exist, and the weight almost always gives them away. Check these before anything else:

1. Weight: it must be 27.04 g. Fakes are frequently underweight or struck in lower-fineness gold. A precise scale is your first filter.
2. Diameter: 36 mm. If it is noticeably off, be suspicious.
3. Edge: the genuine coin has a diagonal reeded edge. A plain or wrong edge is a red flag.
4. Cast vs. struck: genuine coins are struck, so detail is sharp and the surfaces are not grainy or pitted the way cast fakes tend to be.

If your coin passes the weight and dimension tests and you believe it is worth more than a couple thousand dollars, get it authenticated. For a piece in this value range, professional grading from NGC or PCGS is worth the cost. It confirms authenticity, locks in a grade, and typically raises what a buyer will pay.

Where to sell it

Because this is a precious-metal coin worth thousands, sell it where authenticity and price are protected:

• Certified auction (Heritage, Stack's Bowers): best route for a high-grade or certified example, where serious world-coin buyers compete.
• Established coin dealers: a reputable numismatic shop will appraise it on the spot. Get more than one offer.
• Verified collector marketplaces: the Pesoteca dealer directory lists shops by city, and the Pesoteca buy-and-sell forum connects you with collectors directly.

Whatever you do, photograph the obverse, reverse, and edge, and never hand it over before payment. For open online marketplaces, expect counterfeits to circulate, so insist on weight and edge photos and, ideally, deal only in certified coins.

Want a second opinion on your specific coin before you sell? Post clear photos of both sides and the edge in the Pesoteca forum and let collectors weigh in on grade and authenticity. You can also compare it against other Mexican 8 Escudos and the wider Colonial / Viceroyalty era on the site.

Eight escudos Fernando VI, 1751, Mexico mint, assayer MF, Krause KM#150. The year work began on the Royal Palace of Aranjuez and in which Ensenada was consolidating on the peninsula a policy of proportional fiscal reform. In New Spain the Count of Revillagigedo continued as viceroy (1746-1755) with centralized administration and reinforcement of the maritime mail. The ounce weighs 27.06 grams with the 0.916 fineness typical of the Fernando VI pillar type. Produced by milling with a round planchet, pillar reverse with crowned Pillars of Hercules and PLVS VLTRA. MF signature of the assayers. This year is the last of KM#150 before the change to KM#151 that Krause documents from 1752. Pieces of 1751 with the MF signature are the final variant of the first Fernando VI pillar type. That year the New Spain fleet arrived at Cádiz with treasure accumulated over several seasons due to logistical interruptions, a shipment that helped stabilize the peninsular finances. The obverse kept the crowned royal shield with the legend FERDIN VI DEI GRATIA, a formula inherited from the pillar system begun in 1732.
