8 Escudos Carlos III 1762 Gold Coin: Value & Prices

If you inherited an 8 Escudos gold coin dated 1762, here is the short answer: it holds about 0.76 troy ounces of gold, which alone puts its floor near USD 1,900 to 2,000 at current metal prices. Genuine, well-preserved examples of this early Mexico City strike sell for far more, sometimes into five figures at auction. This is one of the few old Mexican coins that is worth real money for both its gold content and its rarity.

One important correction before anything else: this denomination was struck under Carlos III (Charles III), the Bourbon king who took the throne in 1759, not Carlos II. Any listing pairing "Carlos III" with the Habsburg dynasty has it wrong. That distinction matters, because catalog collectors buy by ruler and date, and getting it right protects you when you sell.

What you actually have

The 8 Escudos was the largest gold coin of the Spanish colonial system, the piece English speakers later called the "doubloon." Yours was minted at the Casa de Moneda de México (Mexico City Mint), the oldest mint in the Americas.

The 0.76 ounces of actual gold is the number that matters most for a quick valuation. At a gold spot price around USD 2,500 per ounce, the melt value alone sits near USD 1,900. That is your hard floor. No genuine 1762 8 Escudos is worth less than its gold, and most are worth more.

What it's really worth

Value splits into two layers: the gold, and the numismatic premium on top.

Melt floor. Any authentic example is worth its gold content, roughly USD 1,900 to 2,000, and always finds a buyer. Gold is liquid.

Numismatic premium. This is where 1762 gets interesting. Early Bourbon 8 Escudos from Mexico City, especially the "pillar" and early bust types of the 1760s, are collected worldwide. Circulated examples with real wear typically trade in the USD 2,500 to 5,000 range, above melt because of age, type, and mint. Well-struck examples with clear detail, and anything certified by NGC or PCGS in About Uncirculated or Mint State, climb into five figures. Heritage Auctions and Stack's Bowers have sold choice colonial 8 Escudos from this era for USD 8,000 to well over 20,000 depending on grade, strike quality, and eye appeal.

What drives the premium: grade first, then strike quality and originality. Two coins of the same date can be a decade apart in value if one is worn and cleaned and the other is sharp and original.

The mintage question

Colonial mint records for individual dates in this period are incomplete, so a precise 1762 mintage for the 8 Escudos is not firmly documented across catalogs. Do not treat vague "only a few were made" claims as fact. What is verifiable is that early Bourbon gold from Mexico City survives in modest numbers relative to demand, and that certified high-grade examples are genuinely scarce. Rarity here is real, but it lives in the grade, not in a headline mintage figure.

The myth to ignore

Social media loves to tag any old gold coin as "worth millions." A standard 1762 8 Escudos is not. It is a valuable coin, worth thousands in good condition, but not a museum piece by default. The coins that break records are extreme rarities: pattern strikes, unique assayer varieties, or pieces from shipwreck hoards with documented provenance. If someone quotes you a six-figure price on an ordinary circulated example, they are wrong or selling you something.

How to check if yours is genuine

Gold fakes almost always fail on the physics. Start there.

• Weigh it. A genuine coin weighs 27.03 g. Counterfeits, especially the gold-plated and low-purity fakes coming out of overseas workshops, rarely hit that weight while matching the 36 mm diameter. If the weight is off, stop.
• Measure the diameter. 36 mm. A coin that is the right weight but wrong size (or vice versa) is a red flag for a cast copy.
• Check the edge. This issue has a chain-pattern edge. Cast fakes often show a seam or a soft, mushy edge.
• Inspect the detail. Real dies produce crisp lettering and sharp devices. Casts look soft and grainy under magnification.

For anything you plan to buy or sell above roughly USD 300, get it authenticated. For a coin worth thousands, certified grading from NGC or PCGS is the definitive protection. It confirms authenticity, assigns a grade, and seals the coin in a tamper-evident holder that buyers trust. The grading fee is small against the value at stake.

Where to sell it

Because this is a precious-metal coin, sell only where the buyer can see the coin and verify its weight in front of you.

• A verified numismatic shop from the Pesoteca directory will appraise it on the spot and pay fairly for gold.
• The Pesoteca buy-and-sell forum connects you directly with collectors who understand colonial gold.
• Major auction houses (Heritage, Stack's Bowers) are the right venue for high-grade, certified examples, where competitive bidding tends to beat a flat dealer offer.

Photograph the obverse, reverse, and edge, and record the exact weight before you talk to anyone. Never sell a gold coin to the first online buyer without proof of what it is.

This piece belongs to the Colonial Escudos gold series and the broader Colonial / Viceroyalty era. You can also browse other Mexican 8 Escudos and more coins dated 1762.

Eight escudos Carlos III, 1762, Mexico City mint, assayer MM, Krause KM#155. Krause records the change from KM#153 to KM#155 in 1762 due to a die variation, probably in the crowned shield on the obverse. In August 1762 the English took Havana as part of the Seven Years' War, and Manila in October. Spain would lose Florida to the English the following year under the Treaty of Paris. It was the reign's year of greatest territorial defeat. In New Spain the Marquis of Cruillas reinforced coastal defenses and organized the Junta de Puebla. The ounce weighs 27.06 grams with .916 fineness. Produced by mill with a round planchet. The reverse retains the pillar design, the last period before the iconographic shift to busts that would come a decade later. MM signature of the assayers.
