8 Reales Felipe V 1714 (Silver Cob): What It's Worth

If you inherited a rough, irregular silver coin marked with a Spanish coat of arms and the name PHILIP V, you likely have an 8 Reales silver cob struck in Mexico City in 1714. Most examples trade in the 150 to 800 USD range depending on how clear the design and date are. Clean, well-struck pieces can reach a few thousand. Damaged or badly worn ones sit near their silver value, roughly 20 to 25 USD.

This is not a rare coin in the strict sense. Millions of Spanish colonial 8 Reales (the famous "pieces of eight") were minted, and many survive. What separates a 200 USD coin from a 2,000 USD coin is entirely condition: strike quality, a legible date, full weight, and clean surfaces.

What you actually have

The 8 Reales was the standard large silver coin of the Spanish empire, known in English as the "piece of eight." It circulated worldwide as trade currency, from Europe to Asia via the Manila galleon. Your 1714 example was made by hand at the Mexico City Mint (Casa de Moneda de México) before machine striking arrived, using a process that produced the crude, off-round pieces collectors call cobs (in Spanish, macuquinas).

Specifications, which you should verify against your coin:

Feature	Detail
Denomination	8 Reales
Ruler	Felipe V (Philip V, first Bourbon king of Spain)
Year	1714
Mint	Mexico City (Casa de Moneda)
Weight	25.79 grams
Diameter	35 mm
Metal	Silver, .917 fineness (traditional standard)
Type	Hand-struck cob (macuquina), irregular shape

The irregular outline and rough relief are normal. These coins were cut from a silver bar and struck by hammer, so no two look exactly alike.

What it's worth in 2026

Because cobs vary so much piece to piece, value is a range, not a fixed number. Here is a realistic breakdown:

Condition	What it looks like	Approx. value (USD)
Damaged / heavily worn	No clear date, corroded, clipped	20 to 40 (near silver melt)
Circulated, partial detail	Some shield visible, date weak	100 to 300
Clear date and mint marks	Readable, full weight, decent strike	400 to 900
Sharp, well-centered, certified	Strong detail, NGC/PCGS graded	1,500 to 4,000+

The single biggest value driver is a legible date. A cob with a clearly visible 1714 is worth far more than an otherwise similar coin where the date is off the flan or worn away. Full original weight matters too: colonial coins were often clipped, and a clipped, underweight example loses value.

How to check if yours is genuine

Spanish colonial silver is heavily faked, and cast copies are common. Check the basics first:

• Weigh it. A genuine, unclipped example should be close to 25.79 grams. Use a jewelry scale.
• Measure it. Around 35 mm across the widest point.
• Look at the surface. Real cobs were struck, so detail has crisp edges. Cast fakes look soft, grainy, or show a seam around the rim.
• Silver test. Genuine coins are non-magnetic and have the ring and heft of high-grade silver.
• Be suspicious of any bargain priced below the coin's silver content. That is a red flag for a fake.

For anything you plan to sell above a few hundred dollars, get it authenticated. NGC and PCGS both certify Spanish colonial cobs, and a graded holder removes the buyer's doubt and raises the price you can ask.

Where to sell it

You have a few honest options:

1. A specialist dealer or auction house. Firms like Heritage Auctions and Stack's Bowers handle Spanish colonial silver regularly and reach the collectors who pay top prices. Best for high-grade or certified pieces.
2. A verified numismatic shop from the Pesoteca dealer directory, which can value it in person on the spot.
3. The Pesoteca buy-and-sell forum, where collectors trade directly.

Before selling, photograph the obverse, reverse, and edge in good light, and check the value ranges above. Don't dump it to the first Facebook offer, and never sell precious metal to anyone who won't let you weigh and inspect the piece first.

About "error" coins

Genuine mint errors (off-center strikes, double strikes, die rotation) can raise value. But on hand-struck cobs, most of what people call an "error" is simply the normal irregularity of the process, or post-mint damage like scratches and corrosion. If you think yours has a true error, post clear photos in the Pesoteca forum and let the community weigh in before you assume it's worth extra.

This piece belongs to the reign of Felipe V of Spain (1700-1746). The first Bourbon king in Spain, grandson of Louis XIV of France. His first period of reign (1700-1724) lasted until his abdication in favor of Luis I.

The government of New Spain in 1714 was in the charge of Fernando de Alencastre, duke of Linares, following the Treaty of Utrecht.

The piece's numismatic type is cob, also called hammer-cut coin. The blanks were clipped with shears from a silver bar and struck between hand-held dies, so no cob has an edge or perfectly circular shape. It circulated as a reference trade coin throughout the Atlantic for more than two centuries.

The Mexico mint had been striking cobs almost without interruption since the 16th century. The final years before the 1732 pillar reform 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 Mexico mint assayer active in the period, an official charged by the Royal Treasury with certifying that the silver fineness met the viceregal standard.

The colonial catalogs trace this piece within the families of the Mexico Real de a ocho, with prices that respond to rarity by year and assayer signature.
