8 Reales Resplandor, Hermosillo 1889: Silver Value

If you inherited an old Mexican 8 reales dated 1889 with a sunburst and a Liberty cap on one side, here is the short answer: in worn condition it trades close to its silver value, roughly USD 20 to 30 depending on the silver market. Sharp, high-grade examples of the Hermosillo mint can bring USD 100 or more to collectors. This is a real silver coin, not a fortune, but not junk either.

What you actually have

The 8 reales Resplandor (Spanish for "sunburst") was the standard large silver coin of the Mexican Republic. "Resplandor" refers to the rays of the sun radiating behind the Phrygian cap (a Liberty cap) on the front. Your coin was struck in 1889 at the Hermosillo mint, in the state of Sonora, during the Porfiriato era.

These are the exact specifications, and you can use them to sanity-check your piece:

Feature	Detail
Denomination	8 Reales
Year	1889
Mint	Hermosillo
Metal	Silver .900 (also cited as .9028 fine)
Weight	27.07 grams
Diameter	39 mm
Edge	Reeded
Series	República Mexicana silver 8 reales

At 27.07 grams of .900 silver, the coin contains about 0.786 troy ounces of pure silver. That number matters, because it sets the floor on value. No matter how worn the coin is, it is worth at least its melt value, which moves with the silver spot price.

The front (obverse) shows the Phrygian cap over a burst of sun rays, with the word "LIBERTAD" (Liberty). The back (reverse) shows the Mexican eagle facing forward, perched on a cactus and eating a snake, with the legend "REPÚBLICA MEXICANA." This design ran under the republican octaval standard until the monetary reform of 1905.

Is it rare, and what is it worth?

Most 8 reales from this period are not rare. Millions circulated, and many survive. What separates a USD 25 coin from a USD 150 coin is condition (grade) and mint. Hermosillo (mint mark Ho) is one of the smaller mints, which can add a modest premium among collectors who chase mint sets, but it does not turn a common coin into a jackpot.

Here is a realistic breakdown for the 1889 Hermosillo 8 reales:

Condition	What it looks like	Approximate value (USD)
Well worn (Good to Fine)	Flat details, readable date	Melt value, about 20 to 30
Lightly worn (VF to XF)	Sharp eagle, some luster	35 to 75
About Uncirculated / Mint State	Full detail, original luster	100 and up

These ranges assume a genuine, undamaged coin. Cleaning, scratches, holes, or corrosion cut the value hard, often back down to melt. A coin certified by NGC or PCGS in a high grade sits at the top of these ranges and sometimes above.

The exact price depends on grade, on any original Banxico packaging if applicable, and on the silver spot price the day you sell. Check the grade ranges above and compare against our guide to grading Mexican coins before you accept an offer.

The myth to ignore

Old does not mean valuable. A coin being from 1889 impresses people, but age alone adds almost nothing here. Value comes from real scarcity, collector demand, condition, and metal content. If someone tells you this coin is worth thousands just because it is over a century old, that is not how the market works. The honest number for a typical worn example is the silver value.

How to tell if yours is genuine

Counterfeits and cast copies of Mexican silver 8 reales exist, so verify before you buy or sell:

• Weigh it. A real coin is 27.07 grams. Use a jewelry scale. A light or heavy coin is a red flag.
• Measure it. Diameter should be 39 mm. Use calipers.
• Check the edge. It should be reeded (fine vertical grooves), not smooth or seamed.
• Look at the strike. Fakes often show mushy lettering, wrong font, or a seam where two cast halves join.
• Be suspicious of bargains. Any offer well below the silver value usually means the seller thinks it is fake, or knows it is.

If you are not sure, get it looked at in person before money changes hands.

Where to sell it

To sell your 1889 8 Reales Resplandor from Hermosillo, the safest routes are a verified coin shop from the Pesoteca directory, which can appraise it on the spot, or the Pesoteca buy-and-sell forum where collectors trade directly. Photograph the front, back, and edge, and compare your grade to the ranges above before you commit. Avoid dumping it to the first Facebook buyer, and never sell precious metal to someone who will not show you the piece and weigh it in front of you.

In 1889, Porfirio Díaz governed during the mid-Porfiriato. These were the years of the 1889 Paris Universal Exposition with a Mexican pavilion, and of the railroad's consolidation as the backbone of the economy.

The Hermosillo mint (Ho) was set up in 1835 to handle Sonora's silver without depending on Álamos. 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 .9028 fineness silver with a reeded edge and a theoretical weight of 27.07 grams. The 1889 example from Hermosillo, Sonora corresponds to the phase in the mint's mature stage, near its closing (1835-1895), and is identified on the coin by the mint mark Ho.

To hunt down this Ho piece without overpaying, check both regional shows and professional auction listings. The 1880s-cycle examples from Ho have enough supply to compare edges, original luster, and hairlines across 3 or 4 options before closing a deal. Verify there is no filing on the edge and that the resplandor of the Phrygian cap is not weak from wear; both are marks of circulated examples presented as higher quality.
