8 Escudos Felipe V 1734 Gold Coin: Value & How to Sell

If you inherited or found a 1734 8 Escudos of Felipe V, you are holding one of the highest-value colonial coins Mexico ever produced. This is a large gold coin, 27.06 grams at 0.875 fineness. Even the most worn genuine example carries thousands of dollars in gold alone, and rare, well-preserved pieces have sold for far more at auction.

So the short answer: yes, if genuine, this is worth serious money. How much depends on condition, the mint marks, and whether it is authentic. Colonial gold like this is heavily counterfeited, so verification comes before any price talk.

What this coin actually is

The 8 Escudos was the largest gold denomination in the Spanish colonial system, popularly called an "onza" (ounce). This one dates to 1734, struck under King Felipe V at the Mexico City mint, when that mint was the main silver and gold supplier of the Spanish Empire.

Key identifiers on your coin:

• Assayer initials MF. The assayer was the official who certified the metal's purity. These initials help confirm the coin's origin and date range.
• Mint mark for Mexico City.
• Catalog reference KM#148.

Technical data (check yours against this)

Weigh it on a jewelry scale and measure the diameter with calipers. A genuine coin should land very close to 27.06 g and 36 mm. Anything meaningfully off is a red flag.

What it's worth

Start with the floor. At 27.06 grams and 0.875 fineness, this coin contains roughly 23.7 grams of pure gold, close to 0.76 troy ounces. That gold content alone sets a base value in the low thousands of dollars at current bullion prices, before any collector premium.

Above that floor, the number moves fast with condition and eye appeal. Colonial 8 Escudos in circulated but honest condition typically trade well above melt because collectors want them, not just the metal. Sharp, high-grade examples, especially ones certified by NGC or PCGS, can reach five figures at major auctions. Weak strikes, heavy wear, cleaning, or mount marks pull the price back toward the gold value.

Because the exact figure depends on grade and the specific die variety, treat any single quoted price online with caution. What you can rely on: a genuine 1734 8 Escudos is never a "few dollars" coin. Its floor is the gold, and its ceiling is the collector market.

How to tell if yours is genuine

Colonial gold is one of the most faked categories in the hobby, so slow down before you get excited or before you sell.

1. Weight and diameter first. Compare against the table above. Counterfeits often miss on weight because base metals don't match gold's density.
2. Study the engraving style. Look at the shield, the crown, the lettering, and how the assayer initials and mint mark are cut. Fakes frequently have soft, mushy, or too-perfect details.
3. Confirm the mint and assayer. MF and the Mexico City mint mark should be consistent with 1734 issues.
4. Be suspicious of bargains. Any offer well below the coin's gold value is almost certainly a warning sign, not a deal.

The safest path is professional authentication and grading. A slab from NGC or PCGS both confirms authenticity and sets the grade that determines your price.

About "error" coins

Genuine mint errors (off-center strikes, die rotation, double strikes, recognized varieties) can raise value significantly when verified. But most "errors" people spot on colonial coins are actually post-mint damage: dings, corrosion, or handling marks, which lower value instead. If you think you have a real error, get expert eyes on it before assuming it's worth more.

Where to sell

To sell a 1734 8 Escudos safely:

• A verified numismatic shop from the Pesoteca directory can appraise it on the spot and buy or broker it.

• For a coin this valuable, get it certified first. A graded coin sells faster and for more.

Photograph the obverse, reverse, and edge in good light. Because this is precious metal, only deal with buyers who let you verify the piece and its weight before money changes hands. Don't dump it to the first bidder on social media, and don't accept a lowball from anyone who can't explain their number.

Eight escudos, Felipe V second period, 1734, Mexico mint. That year Juan de Acuña, Marqués de Casafuerte, died in office, having been viceroy since 1722 with twelve uninterrupted years of government. He was succeeded on an interim basis by Juan Antonio de Vizarrón y Eguiarreta, Archbishop of Mexico, who would hold the dual civil and ecclesiastical command until 1740. The ounce weighs 27.06 grams at a fineness of 0.916. Milled with a round planchet under the technical reform introduced in 1732. The reverse shows the crowned Pillars of Hercules over the sea with PLVS VLTRA banners, iconography of the Mexican pillar (columnario) system in force until 1772. The obverse bears the crowned royal shield with the legend PHILIP V DEI GRATIA. The edge was marked with a mechanical inscription that hindered clipping, the main fraud the reform combated. Examples from 1734 are material testimony to the year of political transition in the viceroyalty and are part of the second full year of the Mexican pillar coinage.
