8 Reales Felipe V (1715): The Silver 'Piece of Eight' From Mexico

If you inherited or found a chunky, irregular silver coin marked with a cross and Spanish text dated 1715, you likely have a Felipe V 8 reales cob from the Mexico City mint. Most worn examples sell for roughly 150 to 400 USD. Sharp, fully legible pieces climb into the thousands. This is a genuine early 18th-century "piece of eight," not a modern token, and its value comes from silver content, condition, and how much of the design survived the crude minting process.

What this coin actually is

The 8 reales was the Spanish colonial silver dollar, the coin the English-speaking world called the "piece of eight." This particular type dates to 1715, struck under Felipe V, the first Bourbon king of Spain, at the Casa de Moneda de México (the Mexico City mint).

It belongs to the cob series (in Spanish, macuquina). Cobs were made by cutting a chunk from a silver bar and striking it by hand, without the neat round planchets of later machine-struck coins. That is why your piece looks lopsided, has an uneven edge, and often shows only part of the design. Irregular shape is normal and expected for this type, not a defect.

Specifications

• Metal: Silver
• Weight: 24.92 grams (worn or clipped examples weigh less)
• Diameter: about 35 mm (varies, these were never perfectly round)
• Mint: Mexico City
• Date: 1715
• Ruler: Felipe V
• Type: Cob (macuquina), hand-struck

Because it is close to pure silver, the coin has a floor value tied to its metal content. Even a battered, unreadable example is worth more than its weight in scrap because collectors want early colonial silver.

What a 1715 Felipe V 8 reales is worth

Value on cobs swings hard based on how much of the design you can read. Two coins of the same date and mint can differ by 20x depending on strike and wear. The mint mark, the assayer's initial, and legible legends (the Latin text around the edge) all push the price up.

Condition	What it looks like	Approx. value (USD)
Low grade / clipped	Worn flat, partial or no legends, edges cut	100 to 250
Average circulated	Cross and shield clear, some legend readable	300 to 700
Well-struck / clear date	Full date, mint mark and assayer visible	800 to 2,500
Exceptional / shipwreck-certified	Sharp detail, certified by NGC or PCGS	3,000+

Cobs recovered from documented shipwrecks and sealed in graded holders can command strong premiums, especially when the wreck has a known name and salvage certificate. A common worn example with no story is a few hundred dollars.

Is it rare?

Not in the sense most people hope. The Mexico City mint produced enormous quantities of 8 reales in this era to move the silver pouring out of New Spain into world trade. Millions circulated across the Atlantic and the Pacific. The type is collectible and old, but it is not scarce as a category.

What is scarce is a well-preserved example with a full, readable date and clear mint details. Those are the ones that bring real money. A smooth, worn disc with a faint cross is common and priced accordingly.

The myth: "1715, it must be the treasure fleet"

You may have read that 1715 coins are worth a fortune because of the 1715 Treasure Fleet that sank off Florida. Here is the honest version: coins genuinely recovered from that wreck, with salvage documentation and third-party grading, do carry a premium and can sell for thousands. But a loose 1715 cob with no provenance is just a 1715 cob. Sellers online routinely attach "treasure fleet" language to ordinary coins to inflate the price. Provenance has to be documented to matter.

How to tell if yours is genuine

Colonial cobs are among the most-faked coins on the market, so verify before you buy or celebrate.

• Weigh it. Use a jewelry scale. A full, unclipped example is near 24.92 grams. Cast fakes are often noticeably off in weight or ring dull.
• Measure it. A caliper should read around 35 mm, though genuine cobs vary.
• Look at the surfaces. Hand-struck coins show flat, hammered areas and crisp incuse detail where struck. Cast counterfeits show a grainy, pitted surface and often a seam around the edge.
• Check the design. Genuine pieces carry a cross with castles and lions in the quarters, or a pillars-and-waves design, plus the mint mark and assayer initial. Study reference images of authentic Mexico City cobs before comparing.
• Be suspicious of any deal far below silver value. If someone offers a "1715 silver 8 reales" for a small amount, assume it is fake or clipped.

For anything valuable, third-party certification from NGC or PCGS settles authenticity and adds resale confidence.

Where to sell or appraise it

• A verified numismatic shop from the Pesoteca directory can weigh and appraise the coin in person, which matters for a precious-metal piece.
• The Pesoteca buy-and-sell forum connects you with collectors who actually want colonial silver, often better than a general marketplace.
• Photograph the front, back, and edge in good light before listing, and compare against the value ranges above.

Do not dump it to the first bidder on a social media group. For colonial silver, both authenticity and grade drive the number, and a rushed sale usually leaves money on the table. If your coin has crisp detail or any shipwreck paperwork, get it graded first.

This piece belongs to the reign of Philip V I of Spain (1700-1746). First king of the House of Bourbon in Spain, grandson of Louis XIV of France. His first reigning period (1700-1724) ran until his abdication in favor of Louis I.

The government of New Spain in 1715 was in the hands of Fernando de Alencastre, Duke of Linares, consolidating the new Bourbon order in New Spain.

The numismatic type of the piece is cob (macuquina), also called hammer-cut coin. The planchets were cut with shears from a silver bar and struck between hand dies, so no cob has an edge or a perfectly circular shape. It circulated as the reference commercial coin throughout the Atlantic for more than two centuries.

The Mexico mint had been striking cobs almost without interruption since the 16th century. The last years before the pillar reform of 1732 saw an increase in the volume of registered silver, pressured by European demand and by the mines of Zacatecas and Guanajuato. The dies were signed by the assayer of the Mexico mint active in the period, an official charged by the Royal Treasury with certifying that the silver fineness met the viceregal standard.

Colonial catalogs track this piece within the families of the Mexico Piece of Eight (Real de a ocho), with prices that respond to rarity by year and assayer signature.

A year after Utrecht, with Bourbon reforms beginning the reordering of the empire.
