1733 Mexico 8 Reales (Felipe V): Value & How to Sell

If you inherited or found a 1733 Mexico 8 reales of Felipe V, here is the honest answer: it is a genuine colonial silver coin with real value, typically from a few hundred dollars for a heavily worn example up to several thousand for a sharp, high-grade piece. It is not a coin worth a fortune by default, but it is far more than pocket change, and in 2026 demand for early Mexican silver stays strong.

The 8 reales was the largest silver denomination of the Spanish colonial system, the famous "piece of eight" that circulated worldwide. The 1733 coin comes from what collectors call the second period of Felipe V's coinage at the Mexico City Mint (Casa de Moneda de México). These are pre-"pillar" (columnario) coins, struck by hand before the mint modernized its methods, which is part of why they draw collector interest.

What you actually have

Feature	Detail
Denomination	8 reales (largest silver unit)
Ruler	Felipe V (first Bourbon king of Spain)
Date	1733
Mint	Mexico City (México)
Metal	Silver, .917 fine
Weight	27.04 grams
Diameter	40 mm
Edge	Laureate (laurel-leaf) edge

That weight and fineness matter to a US reader for one reason: even in rough shape, the coin has a silver floor. At roughly 0.797 troy ounces of pure silver, the melt value alone puts a baseline under it. But almost nobody sells a genuine 1733 8 reales for melt, because the collector value is higher.

What it's worth in 2026

Value on this coin swings hard with grade and eye appeal. A hand-struck colonial coin is judged on how much detail survives, how clean the surfaces are, and whether it has been cleaned, holed, or damaged.

• Heavily circulated, worn, or damaged: roughly a few hundred dollars, sometimes closer to its silver value if problems are severe.
• Mid-grade, honest wear, clear date and design: commonly the high hundreds to low four figures.
• High grade with sharp strike and original surfaces: several thousand dollars, with the best certified examples pushing higher at auction.

Early Mexico City 8 reales of this type have sold across a wide band at Heritage Auctions and Stack's Bowers, driven by grade and whether the piece is certified by NGC or PCGS. A slabbed, problem-free example will always outperform a raw coin of the same grade, because buyers pay a premium for certified authenticity.

The myth to kill

Old does not mean priceless. A 1733 coin sounds ancient to a US reader, and "nearly 300 years old" gets quoted like it means millions. It does not. Millions of pieces of eight were struck across the colonial era, and the 1733 8 reales is collectible, not ultra-rare. The pieces that hit record prices are the finest-known survivors in top grade, not average worn examples. If a listing screams "rare 300-year-old Spanish treasure worth a fortune," treat it as marketing, not a valuation.

How to tell if yours is genuine

Fakes and modern replicas of colonial 8 reales are everywhere, so verify before you get excited or before you buy.

1. Weigh it. Use a jewelry scale. Genuine coins run near 27.04 grams. A significantly light coin is a red flag.
2. Measure it. A caliper should read about 40 mm across.
3. Check the edge. This issue has a laureate (laurel-leaf) edge, not a plain or reeded edge. A smooth edge on a supposed 1733 8 reales is a warning sign.
4. Look at the engraving, mint mark, and assayer. Hand-struck coins show irregular but consistent period style. Cast fakes look mushy or have seams.
5. Be suspicious of any deal below silver value. No honest seller prices a real one under melt.

When in doubt, submit it to NGC or PCGS for authentication and grading. Certification costs money but it is the difference between guessing and knowing, and it raises what buyers will pay.

Errors and varieties

Genuine mint errors (off-center strikes, die rotation, doubled strikes) can multiply value on colonial coins. But most "errors" people spot online are post-mint damage: dings, corrosion, and cleaning, not factory errors. If you think you have a true error, get a second opinion before assuming it adds a premium.

Where to sell it

• A verified numismatic dealer who can examine the coin in hand and appraise it on the spot. Get more than one quote.
• Major auction houses (Heritage, Stack's Bowers) if the coin is high grade or certified. Auction reaches serious collectors and usually gets the strongest price for a good example.
• Certified-coin marketplaces once it is graded by NGC or PCGS.

Before you sell anything: photograph the front, back, and edge in good light, know the weight, and compare against the price band above. Do not dump it to the first offer on a social-media group. Colonial silver is easy to undersell if you do not know the grade.

Not sure what grade yours falls in, or whether it's the real thing? Post clear photos of the obverse, reverse, and edge in the Pesoteca forum and let collectors who handle these coins weigh in before you sell.

This piece belongs to the reign of Felipe V II of Spain (1724-1746 (second stage)). He returned to the throne in 1724 after the premature death of Luis I. His second period ends with the monarch's death in 1746.

The government of New Spain in 1733 was under Juan de Acuña, Marqués de Casafuerte, the first full year of pillar coinage.

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 real the most trusted trade coin of its time.

The Mexico mint formally introduced the mechanized striking of pillar reales in 1732, and from then on the crowned Mo 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 dies were signed by the Mexico mint assayer active in the period, the official charged by the Real Hacienda with certifying that the silver fineness met the viceregal standard.

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's signature.

A year of consolidation of the pillar real, with a laureate edge that hindered the fraudulent clipping of silver.
