1809 Mexico 8 Reales Fernando VII: Value & Silver Content

Your 1809 Mexico 8 Reales silver coin has a real value floor: it holds about 24 grams of 0.900 fine silver, which alone is worth roughly 20 to 25 USD at today's spot price. Most circulated examples trade between 20 and 80 USD. Well-preserved or certified pieces can bring several hundred dollars or more. Here is how to figure out which one you have.

What you actually have

The 8 Reales was the Spanish colonial silver dollar, minted in Mexico City while the country was still the Viceroyalty of New Spain. Your coin carries the portrait of Fernando VII (Ferdinand VII of Spain) and the 1809 date. This is the coin that circulated worldwide and became the model for the US dollar itself.

The hard specs, which matter for spotting fakes:

• Metal: silver, 0.900 fine (90% pure)
• Weight: 26.9 grams
• Diameter: 40.01 mm
• Mint: Mexico City (México)
• Assayer mark: TH
• Edge: incuse (lettered/decorated edge design)

The pure silver content works out to about 24.2 grams, roughly 0.78 troy ounces. That silver gives every genuine example a price floor, no matter how worn it is.

How much is it worth in USD

Value comes down to condition (grade) and whether the coin has been authenticated. Old does not mean rare here: millions of 8 Reales were struck across the colonial period, so a beat-up example is worth close to its silver.

Condition	What it looks like	Approx. value (USD)
Heavily worn / damaged	Flat details, scratches, cleaning marks	18 to 30 (near melt)
Circulated (Fine to VF)	Readable design, moderate wear	40 to 120
High grade (XF to AU)	Sharp detail, light wear	150 to 500
Uncirculated / certified MS	No wear, original luster, slabbed	800 to several thousand

These are broad ranges because a single point of grade can move the price a lot at the top end. A worn coin with a cleaning or a hole is worth silver value only. A crisp, original, NGC or PCGS certified example is where the real money sits.

Watch out for the 1809 date specifically

1809 falls in the transition period after Fernando VII took the throne. Some early portrait dies were rushed or improvised, and there are recognized bust varieties from these first years that collectors pay a premium for. If your coin looks unusual for the type, that is worth checking, not dismissing.

How to tell if it is genuine

Counterfeit 8 Reales are common because the coin is famous and silver is valuable. Run these checks before you spend or sell:

1. Weigh it. A real one is 26.9 grams. Off by more than a fraction of a gram, be suspicious.
2. Measure it. 40.01 mm across. Fakes are often slightly small or thick.
3. The ping test. Genuine 0.900 silver rings with a high, sustained tone when balanced on a fingertip and tapped. Base-metal fakes sound dull and short.
4. Check the edge. The incuse edge design is hard to fake well. Cast copies often show a seam or mushy edge.
5. When in doubt, certify. For anything you think is above roughly 200 USD in value, NGC or PCGS grading is the definitive answer and adds resale confidence.

Where to sell it

• Certified coin dealers and auction houses (Heritage, Stack's Bowers) for high-grade or certified pieces. They reach serious buyers and get top prices.
• Established collector forums and groups for mid-range circulated coins, where you deal directly with people who know the series.
• Bullion buyers as a last resort for worn coins, though you will only get silver value there.

Always photograph the front, back, and edge before you sell, and never accept a lowball offer without checking the ranges above. This coin is part of the broader Colonial 8 Reales series, and prices vary a lot by mint, year, and assayer, so compare to the exact match, not just any 8 Reales.

Have one in hand and not sure which grade it falls into? Post clear photos of both sides and the edge in the Pesoteca forum and get a read from collectors who handle these regularly.

This piece belongs to the reign of Fernando VII of Spain (1808-1833). Son of Carlos IV. In 1808 he was forced to abdicate to Napoleon, and was held captive until 1814. Under his reign almost all the American colonies were lost.

The government of New Spain in 1809 was led by Pedro de Garibay and later Francisco Javier de Lizana y Beaumont, interim governments during the dynastic crisis.

The numismatic type of the piece is bust, introduced in 1772 under Carlos III. The obverse shows the portrait of the king in the neoclassical style and the reverse the royal crowned shield with the Golden Fleece. The edge is laurel or corded, and all examples were struck on a screw press, with Latin legends spelling out the monarch's titles and dignities.

The Mexico mint had migrated to the bust standard in 1772. Under Carlos III and Carlos IV the highest annual production of struck silver of the viceroyalty was recorded, feeding trade with the Philippines via the Manila Galleon (Nao de China) and the payment of the situado to the Antilles. The assayer's initials declared on the piece are TH, an official of the Royal Treasury charged with certifying the silver fineness (0.930 and later 0.903) per the viceregal standard.

The Krause catalog references this piece under KM#110, useful for cross-checking the record with international auction listings.

A provisional year of issue during the dynastic crisis, with the Mexico mint continuing operations under interim authorities.
