1749 Mexico 8 Reales Fernando VI: Value & How to Sell

If you inherited or found a 1749 Mexico 8 Reales with the name FERDIN VI on it, you are holding a real piece of Spanish colonial silver, not a modern copy or a token. In 2026, a genuine example is worth anywhere from about 100 USD in worn condition to several thousand USD for a sharp, certified coin. Here is what drives that number and how to check yours.

What you actually have

This is an 8 Reales, the famous "piece of eight," struck at the Mexico City mint (the Ceca México) in 1749 under King Fernando VI of Spain. It is the classic Spanish colonial dollar that circulated worldwide, including in the early United States, where it was legal tender for decades.

Key specs, verify these against your coin:

• Metal: silver, .900 fine (also written 0.900 or ley 0.9)
• Weight: 27.07 grams
• Diameter: 40 mm
• Edge: laureate (a decorative pattern around the rim)
• Assayer: MF (the initials of the mint official, found near the coat of arms)
• Type: "pillar dollar" or "columnario" era colonial issue

If your coin weighs noticeably less than 27 grams or measures far off 40 mm, treat it as suspect until it is authenticated.

What it's worth in 2026

Two things set the floor and the ceiling. The floor is the silver itself: at roughly 24.4 grams of pure silver, the melt value moves with the spot price of silver, so even a heavily worn example is never "worthless." The ceiling is condition and certification. A crisp coin with full pillars, clear legends and original luster, graded by NGC or PCGS, sells for a large multiple of a beat-up circulated one.

Condition	Description	Approx. value (USD)
Low grade / heavily worn	Design flat, details soft, possible corrosion	80 to 200
Circulated, problem-free	Clear date, readable legends, honest wear	200 to 600
High grade, uncertified	Sharp detail, minor wear, some luster	600 to 1,500
Certified Mint State (NGC/PCGS)	Fully struck, original surfaces	2,000 and up

These are working ranges for the reader trying to value an inherited coin, not a fixed quote. Pillar 8 Reales in true Mint State from scarce dates and clean strikes have crossed several thousand USD at Heritage Auctions and Stack's Bowers. Most coins that turn up in a family collection, though, fall in the circulated band.

Is it rare?

Honest answer: the type is collectible but not rare. Mexico City produced 8 Reales in large numbers across the colonial period, and 1749 examples exist in decent supply. What makes one coin worth 150 USD and another worth 2,000 USD is almost entirely condition and eye appeal, plus certification. A common date in exceptional grade beats a scarce date that is worn and damaged.

Die varieties do exist (letter positions, minor die states) that specialists at NGC or PCGS can distinguish, and those can add a premium. For a casual seller, assume yours is a standard example unless a grader tells you otherwise.

How to tell if yours is genuine

Counterfeits of colonial 8 Reales are common, so run these checks before you get excited or pay anyone.

1. Weigh it. A real one is 27.07 grams. Cast fakes are usually off.
2. Measure it. 40 mm diameter.
3. The ping test. Balance the coin on a fingertip and tap it gently. Genuine .900 silver rings with a high, sustained tone. Base-metal fakes sound dull and short. This is a hint, not proof.
4. Check the edge. It should show the laureate pattern, not a smooth or seam-lined edge.
5. When in doubt, certify. For any coin you think is worth more than a few hundred dollars, submitting it to NGC or PCGS is the only definitive answer. Their holder confirms authenticity and grade, and it raises resale value.

Where to sell it

You have a few real options in the US and internationally:

• Auction houses (Heritage, Stack's Bowers) for high-grade or certified pieces. Best prices, but they take a commission and are worth it only above a certain value.
• Established coin dealers who handle world coins. Fast, but expect a buy price below retail.
• Certified marketplaces and collector forums, where certified coins move well.
• Pesoteca: list or value it through the Pesoteca buy/sell forum among collectors, or find a vetted shop in the Pesoteca dealer directory.

Whatever route you choose, photograph the obverse, reverse and edge in good light, note the weight, and never sell to the first lowball offer. Because this is precious metal, only deal with buyers who let you verify the coin before money changes hands. This piece belongs to the Colonial 8 Reales series, the Viceroyalty era of Mexican coinage.

This piece belongs to the reign of Fernando VI of Spain (1746-1759). Son of Felipe V. His reign was marked by neutrality in the European conflicts and by Enlightenment reforms in Spain and the Indies.

The government of New Spain in 1749 was in the hands of Juan Francisco de Guemes y Horcasitas, count of Revillagigedo, the first viceregal term of the Guemes family.

The numismatic type of the piece is pillar (columnario), officially introduced in New Spain in 1732. The reverse shows two crowned globes between the Pillars of Hercules with the motto PLVS VLTRA, and for the first time the coin was struck on a screw press with a laureate edge, which reduced the fraudulent clipping of silver and made the pillar dollar the most trusted trade coin of its era.

The Mexico City Mint formally introduced the mechanized striking of pillar dollars in 1732, and from then on the crowned Mo mint mark was accompanied by the assayer's initials. Production was enormous, exported as trade money to the Philippines, China, Protestant Europe, and the 13 English colonies. The assayer's initials declared on the piece are MF, the Royal Treasury official charged with certifying the silver fineness (0.930 and later 0.903) per the viceregal standard.

The Krause catalog references this piece under KM#104.1, useful for cross-checking the listing against international auction records.

A year of fiscal stability under Fernando VI, with silver exports at high levels.
