8 Escudos Fernando VI 1749: The Colonial Gold Onza

If you inherited an 8 Escudos Fernando VI dated 1749, you are holding one of the classic gold coins of colonial Mexico, and it is worth real money. This is not a common piece worth a few dollars. Genuine examples in collectible condition trade from roughly 2,000 USD to well over 10,000 USD depending on grade, driven by both its gold content and its status as an early Bourbon-era gold onza struck in Mexico City.

Here is what you actually have, what it is worth, and how to make sure it is real before you sell.

What this coin is

The 8 escudos was the largest gold coin of the Spanish colonial system, often called an "onza" (ounce). This one was struck in 1749 at the Casa de Moneda de México (the Mexico City Mint) during the reign of Fernando VI, one of the Bourbon kings of Spain. New Spain (colonial Mexico) supplied a huge share of the gold and silver that circulated across the Spanish empire, and Mexico City coins like this one traveled the world.

Key specs to verify against your coin:

• Metal: gold, .875 fine (21 karat)
• Weight: 26.99 grams
• Diameter: 36.22 mm
• Edge: reeded (milled)
• Mint: Mexico City (Casa de Moneda de México)
• Assayer mark: MF
• Year: 1749 (single year of this issue)

That weight matters. A genuine coin sits at 26.99 grams. Fakes almost always miss the mark on weight because they use lower-purity gold or base metal cores. If your coin is off by more than a fraction of a gram, be suspicious.

What it is worth in USD

There is no single number, because grade drives everything. Two 1749 8 escudos can differ by thousands of dollars depending on wear, surfaces, and whether the coin has been certified by NGC or PCGS.

A realistic framework:

The floor under any genuine example is its gold content. At 26.99 grams of .875 fine gold, the coin contains about 0.76 troy ounces of pure gold. That means it can never be worth less than the daily gold spot price for that amount of metal, which is the number to check first before anyone quotes you a "deal." Anything above melt is the collector premium for its age, condition, and rarity.

Be careful with the melt floor: a heavily worn or mounted (ex-jewelry) coin often trades close to melt only, because its collector value is destroyed. A crisp, original coin carries a large premium over melt.

Is it rare?

Colonial 8 escudos were struck in far smaller numbers than the silver 8 reales, and they saw hard use. Exact mintage figures for the 1749 Mexico City issue are not cleanly documented, which is normal for coins of this era. Survival is what counts for value, and high-grade survivors are genuinely scarce. Circulated examples come up at auction with some regularity; problem-free Mint State pieces are the ones that command the top figures.

Because 1749 is the only year for this specific issue, there is no year-to-year variety to chase. There can be minor die varieties (letter positions, small striking differences) that specialists at NGC or PCGS distinguish, but for most sellers the coin is simply a 1749 8 escudos.

How to tell if yours is genuine

This coin is faked, precisely because it is valuable. Run these checks before you trust any offer:

1. Weigh it. A real one is 26.99 grams. Use a scale accurate to 0.01 g. Underweight is a red flag; many counterfeits use lower-purity gold or a base-metal core.
2. Measure it. 36.22 mm diameter. Check the edge is reeded, not smooth or seamed.
3. Look for solder or mount marks. Many of these were worn as jewelry. Filed edges, a solder blob, or a smoothed rim cut the value hard.
4. Get it certified for anything above a few thousand dollars. Grading by NGC or PCGS is the definitive proof of authenticity and grade, and a certified coin sells faster and higher. The fee is small next to what this coin is worth.

If you plan to buy or sell above the melt value, professional authentication is not optional. It is the difference between a confident sale and getting burned.

Where to sell it

For a coin at this value level, sell where buyers can verify what they are getting:

• Certified auction houses. For high-grade pieces, major numismatic auctions reach the buyers who pay top prices for colonial gold.
• A verified numismatic dealer from the Pesoteca directory, who can appraise it in person and pay based on grade and metal.
• The Pesoteca buy-and-sell forum, where collectors trade directly.

Whatever route you choose, photograph the obverse, reverse, and edge clearly, and get the weight on record. Do not dump a coin like this to the first offer on a general marketplace, where fakes are common and buyers lowball genuine pieces.

Eight escudos, Fernando VI, 1749, Mexico mint, assayer MF, Krause KM#150. The first full year after the Treaty of Aix-la-Chapelle of 1748, which ended the War of the Austrian Succession. Fernando VI was consolidating his policy of neutrality, and his minister Ensenada was launching the Cadastre that would bear his name in peninsular Spain, a pioneering attempt at proportional taxation. In New Spain, the Count of Revillagigedo continued as viceroy. The ounce weighs 27.06 grams at .916 fineness. Produced by mill press on a round planchet, with a classic pillar reverse. Krause references KM#150 as the now-stabilized pillar type of Fernando VI in Mexico. The MF assayers' initials appear in the field. Pieces of this year bear witness to a decade of relative imperial peace that allowed New Spain to consolidate its role as the crown's leading supplier of precious metals.
