Mexican 8 Reales Hermosillo 1893: Value & Silver Content

If you inherited an 1893 Mexican 8 Reales from the Hermosillo mint, here is the honest answer: in worn condition it trades close to its silver value, roughly 18 to 25 US dollars, but clean, sharp examples with strong detail can bring 100 to 300 dollars or more. This is a real silver coin, not a fortune-maker, and this page tells you exactly how to check yours.

What you actually have

The coin reads 8 Reales and shows a radiant Phrygian cap (the "resplandor" or sunburst design) on one side and the Mexican eagle on the other. Yours was struck at the Hermosillo mint in the state of Sonora, marked by a small Ho mint mark. Collectors and dealers catalog it as KM#377.9, part of a large family of 8 reales sunburst coins made across Mexican regional mints during the 1800s.

"Resplandor" is Spanish for the radiant sunburst you see behind the Phrygian cap. That design was the standard for the 8 reales through much of the 1800s.

The silver in it (this sets the floor)

Spec	Figure
Weight	27.07 grams
Diameter	39 mm
Edge	Reeded
Fineness	.903 silver (roughly 0.786 oz pure)
Catalog	KM#377.9
Mint	Hermosillo (Ho), Sonora

Because it carries close to eight-tenths of an ounce of pure silver, the coin can never be worth less than its melt value. That silver floor moves with the market, but it means even a beat-up example is worth something.

What it's worth in 2026

Value for these coins is driven by condition (grade), not just age. Being from 1893 does not make it rare on its own. Millions of 8 reales circulated across Mexico. What matters is how sharp the sunburst and eagle are, whether the high points are worn flat, and whether the coin has been cleaned (cleaning hurts value).

Condition	Approximate value (USD)
Heavily worn / cleaned	18 to 25 (near melt)
Moderate wear (VF)	30 to 70
Light wear, sharp detail (XF/AU)	100 to 250
Uncirculated, certified	300 and up

The Hermosillo mint produced fewer of these than the giant mints at Mexico City or Zacatecas, and 1893 was near the end of the reales system before Mexico moved fully to the decimal peso. That regional angle gives well-preserved Hermosillo examples a modest premium among specialists, but it does not turn a worn coin into a windfall.

The myth to ignore

Stories online claim old Mexican silver coins are worth thousands just for being old. For a standard, circulated 1893 8 reales, that is false. Real four-figure prices go to top-grade certified examples, rare die varieties, or scarce mint-year combinations, not to the average coin in a shoebox. Anyone offering you far below the silver value, or promising a fortune sight unseen, is not being straight with you.

How to check what yours is worth

1. Weigh and measure it. Use a jewelry scale and a caliper. Genuine pieces are close to 27.07 grams and 39 mm. Counterfeits of Mexican colonial and republican silver are common, so a weight that's off is a red flag.
2. Confirm the mint mark and details. Look for the Ho mint mark and the assayer's initials. Check the engraving style against verified references; fakes often get the eagle or sunburst detail wrong.
3. Grade it honestly. Photograph the front, back, and edge in good light. Compare the wear on the high points to graded examples. If it looks uncirculated, professional certification (NGC or PCGS) is worth the cost.
4. Never accept an offer below melt. If someone offers less than the silver value, walk away.

Where to sell it

Sell to buyers who will show you the coin, its weight, and a clear price. A verified numismatic dealer can appraise it on the spot, and the Pesoteca buy-and-sell forum connects you directly with collectors. Because this is precious metal, verify before you pay or ship. Post clear photos of both sides and the edge in the community forum if you want a second opinion before selling.

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

The Hermosillo mint (Ho) was set up in 1835 to handle Sonora's silver without depending on Alamos. It closed in 1895 with the centralizing reform of the Porfiriato.

Ho pieces have low mintages compared to Mexico City or Zacatecas. Late years (1893-1895) are harder to find in good grade.

For catalog reference, this mint's variant is listed as KM#377.9 in Krause. The piece is silver of .9028 fineness with a reeded edge and a theoretical weight of 27.07 grams. The 1893 example from Hermosillo, Sonora corresponds to the mint's final operating years (1835-1895) and is identified on the coin by the Ho mint mark.

To hunt down this Ho piece without overpaying, check both regional fairs and professional auction listings. Examples from the 1890s cycle at Ho have enough supply to compare edges, original luster, and dotting across 3 or 4 options before closing. Verify the absence of filing on the edge and that the radiance of the Phrygian cap isn't weak from wear; both are marks of circulated examples presented as higher quality.
