8 Reales Agustín de Iturbide 1822: Value & Prices

If you inherited an 1822 8 Reales showing the profile of Agustín de Iturbide, you are holding a real silver coin from the first year of independent Mexico. Most examples in worn, circulated condition trade for roughly 100 to 500 USD. High-grade certified pieces can reach several thousand. Condition, not just age, decides everything.

This is one of the more historically significant Mexican silver coins a US collector can inherit, because 1822 was a single-year issue struck during the short-lived First Mexican Empire (Primer Imperio Mexicano). That short window is exactly why it draws attention. Here is what drives the price and how to check what yours is worth in 2026.

What this coin actually is

The 8 Reales was the Spanish-colonial-standard silver dollar of the Americas, the coin that became known worldwide as the "piece of eight." This particular type belongs to the 8 Reales Coloniales series and was struck at the Mexico City mint (Ceca México) under assayer JM.

Key specs, exactly as recorded:

• Metal: Silver 0.900 fine (90 percent silver)
• Weight: 26.79 grams
• Diameter: 37 mm
• Edge: incuse (recessed lettering)
• Year: 1822 only, a single-year issue
• Era: First Mexican Empire

Because it is genuine 0.900 silver, this coin always has a floor value at melt (its silver content), no matter how worn it is. That silver alone is worth roughly 15 to 20 USD depending on the spot price when you sell. The numismatic premium above that comes from the history, the short issue window, and the grade.

What it is worth by condition

Condition	What it looks like	Approximate value (USD)
Heavily circulated	Smooth, worn details, readable date	100 to 250
Moderately circulated (VF)	Clear portrait, some wear on high points	250 to 500
About Uncirculated (AU)	Slight rub, most detail sharp	500 to 1,500
Certified Uncirculated (MS-63 to MS-65)	Full luster, crisp strike	2,000 to several thousand

These are working ranges, not fixed quotes. A raw coin sold quickly online lands at the low end. A piece certified by NGC or PCGS in a high Mint State grade can pull far more, because buyers pay for the guarantee of authenticity and grade. If your coin is genuinely uncirculated, getting it graded is usually worth the fee.

The myth to ignore

Being from 1822 does not automatically make this a five-figure rarity. Plenty of people assume an "early independence" coin means instant fortune. The reality: a worn example is a nice 200-dollar historical piece, not a retirement fund. Value climbs sharply only with high grade and clean certified authenticity. Age alone is not enough.

That said, this type is scarcer than most Mexican silver a US household inherits, and demand from collectors of early-empire coinage is steady. It is a real coin worth taking seriously, just not a lottery ticket.

How to tell if yours is genuine

Counterfeits of early Mexican silver exist, so verify before you celebrate or sell.

1. Weigh it. A genuine coin weighs 26.79 grams. Anything meaningfully off is a red flag.
2. Measure it. Diameter should be 37 mm.
3. Check the edge. It should show incuse (recessed) edge lettering, not a smooth or reeded modern edge.
4. The ping test. Real 0.900 silver gives a high, ringing tone when gently balanced and tapped. Base-metal fakes sound dull and short.
5. Get it certified. For any coin you think is worth more than a few hundred dollars, NGC or PCGS grading is the definitive answer. It confirms authenticity and locks in a grade buyers trust.

Use the coin grading guide to place your piece on the condition scale before you shop it around.

Where to sell it

Because this is a precious-metal coin with a real silver floor, you will always find a buyer. The question is getting a fair price.

• Verified dealers: A numismatic shop from the Pesoteca directory can appraise it on the spot and pay fairly.
• Collector marketplace: The Pesoteca buy-and-sell forum puts you in front of collectors who actually know this type and pay for it.
• Auction: For a certified high-grade example, a numismatic auction house reaches serious buyers of early Mexican silver.

Before listing, photograph the obverse, reverse, and edge clearly, and note the weight. Serious buyers will ask for exactly that. Avoid dumping it to the first offer on general marketplaces, where prices run low and fakes run high.

This piece belongs to the First Mexican Empire of Agustín I, a brief constitutional monarchy that ruled Mexico between May 1822 and March 1823, when the emperor abdicated and the Republic was proclaimed.

The government of independent Mexico in 1822 was in the hands of Agustín de Iturbide, proclaimed Emperor Agustín I that year, ruling the First Mexican Empire.

The piece belongs to the coinage of the First Mexican Empire (May 1822 to March 1823). Emperor Agustín I was crowned in the Metropolitan Cathedral on July 21, 1822. His 8-reales kept the colonial standard and fineness but replaced the royal bust with Iturbide's portrait and the royal shield with the crowned imperial eagle.

The Mexico City mint had been striking cob coinage almost without interruption since the 16th century. The final years before the milled (columnaria) reform of 1732 saw an increase in the volume of registered silver, driven by European demand and by the mines of Zacatecas and Guanajuato. The assayer's initials declared on the piece are JM, the Royal Treasury official charged with certifying the silver fineness (0.930 and later 0.903) under viceregal standards.

The Krause catalog references this piece under KM#305, useful for cross-checking the record against international auction listings.
