8 Reales Resplandor, Álamos 1893: Value & Silver Content

If you inherited or found an 8 Reales Resplandor dated 1893 with an "As" mint mark, here is the straight answer: it contains about 0.79 troy ounces of pure silver, so it has a hard floor of roughly 22 to 26 USD in metal alone at current silver prices. Whether it is worth more than that depends on wear (grade) and how scarce the Álamos date is. This is a common circulation coin, not a rarity, so most examples trade at melt to a modest premium.

What you actually have

The 8 Reales Resplandor was Mexico's workhorse silver coin for most of the second half of the 19th century. It was money, not a commemorative. Yours came from the mint at Álamos, Sonora (that is what the As mint mark means) in 1893. Every regional Mexican mint used its own initials back then: Mo for Mexico City, Zs for Zacatecas, Cn for Culiacán, and As for Álamos.

"Resplandor" (Spanish for "radiance" or "sunburst") is the nickname for the reverse design. It shows a Phrygian cap (a liberty cap) with the word LIBERTAD, sitting on top of a fan of rays spreading out in every direction like a sun. That burst of rays is the resplandor, and it is the most recognizable Mexican 8 Reales design of the 1800s. The other side (the obverse) shows the Mexican republican eagle facing forward with the legend REPÚBLICA MEXICANA.

The specs that matter

Feature	Detail
Denomination	8 Reales
Year	1893
Mint	Álamos, Sonora (mint mark As)
Weight	27.07 g
Fineness	0.903 silver (marked 10 Ds 20 Gs = 10 dineros 20 granos)
Pure silver content	about 24.4 g, roughly 0.79 troy oz
Diameter	39 mm
Edge	Reeded
Type struck through	1897

A note on fineness: you will often see this coin rounded to 0.900 in catalogs, but the actual struck standard is 0.9028. That is why the pure silver math comes out to about 0.79 troy ounces.

How much is it worth in USD

Start with the silver floor. At about 0.79 troy oz of fine silver, the metal alone is worth roughly 22 to 26 USD depending on the daily silver spot price. No 1893 Álamos 8 Reales in decent shape sells for less than that, because it can always be melted.

Above the floor sits the collector premium, and that is driven by two things:

1. Grade (condition). A worn, heavily circulated coin with soft details brings little over melt. A sharp, lightly circulated example with crisp rays, a clean cap, and readable letters brings a real premium. An uncirculated or certified high-grade piece can be worth several times melt.
2. Scarcity of the date and mint. Álamos is a smaller regional mint, so an As example can carry a bit more interest than a common Mexico City coin of the same type, but 1893 is not a headline rarity.

For a realistic figure, do not trust a single "catalog value." Look at recent sales of coins in the same grade and mint. Certified examples (graded by NGC or PCGS) sell for consistent, verifiable prices, which is the best benchmark you can use.

Is it rare

Honestly, no, not in the way people hope. Millions of 8 Reales Resplandor coins were struck across many mints and years, and they survive in large numbers because they were saved and traded worldwide. What makes any single example valuable is grade and mint, not just age. An 1893 date does not make it a fortune. A pristine, certified example from a smaller mint like Álamos is where the money is.

How to tell if yours is genuine

Counterfeits of Mexican 8 Reales exist, so run these quick checks:

• Weight. A genuine coin weighs close to 27.07 g. If yours is noticeably light, be suspicious.
• Diameter. It should measure about 39 mm.
• Magnet test. Silver is not magnetic. If a magnet sticks, it is not real silver.
• Edge. The edge should be reeded (finely grooved), not smooth or seamed.
• Detail sharpness. On real struck coins the cap, the rays, and the lettering are crisp. Cast fakes look soft, blurry, or have a grainy surface and sometimes a faint casting seam.

If you still are not sure, a simple density (specific gravity) test or an opinion from a specialist will settle it. For anything you think might be high grade, professional certification pays for itself.

Where to sell it

Use the Pesoteca shop directory to find dealers and buyers by region. Before you accept any offer, compare your coin against other pieces in the Republican silver 8 Reales series so you know the going rate for your specific year, mint, and grade. That way you are negotiating with real numbers, not a guess.

Sitting on a box of these and not sure which ones are keepers? Post clear photos of the obverse, reverse, and edge in the Pesoteca forum and we will help you sort the melt coins from the ones worth grading.

In 1893 Porfirio Diaz was in office. The years before the monetary reform of Jose Yves Limantour (1896-1905) that would close the provincial mints and establish the gold standard.

The Alamos mint (As) reopened in 1862 during the French Intervention to provide liquidity to the silver mining region of southern Sonora. It worked until 1895 when Porfirian centralization concentrated minting in Mexico and Zacatecas.

As pieces are sought by collectors of the northwest and by mining theme. Annual mintages are relatively low compared with Mexico or Zacatecas.

In catalog reference, the variant of this mint is listed as KM#377 in Krause. The piece is silver at .9028 fineness with a reeded edge and a theoretical weight of 27.07 grams. The 1893 example of Alamos, Sonora corresponds to the phase in the mature stage of the mint, near its closure (1862-1895) and is identified on the coin by the As mint mark.

To chase this As piece without paying a premium, check both regional fairs and professional auction listings. The examples of the 1890s cycle in As have enough supply to compare edges, original luster and striking among 3 or 4 options before closing. Verify the absence of filing on the edge and that the radiance of the Phrygian cap is not weak from wear; both are marks of circulated examples presented as superior quality.
