8 Reales Oaxaca 1889 Silver Coin: Value & Prices

If you inherited an 1889 Mexican 8 Reales from the Oaxaca mint, here is the short answer: in worn condition it is worth its silver, roughly the melt value of about 24 grams of pure silver, but a clean, high-grade example with the right mint and assayer marks can sell for a solid multiple of that. In 2026, the metal alone gives this coin a hard price floor.

This is the classic Mexican "cap and rays" 8 Reales, called the Resplandor in Spanish (it means "radiance," referring to the sunburst design). It was struck across many Mexican mints for most of the 19th century. Yours carries the Oaxaca mint mark and the 1889 date.

What this coin actually is

The 8 Reales was the workhorse silver dollar of Mexico, the direct ancestor of the famous Spanish milled dollar that circulated worldwide. This 1889 issue belongs to the Restored Republic and Porfiriato period. Key specs, which you should verify on your own piece:

• Weight: 27.07 grams
• Diameter: 39 millimeters
• Fineness: .900 silver (technically struck to the .9028 republican standard)
• Actual silver content: about 24.4 grams of pure silver
• Edge: reeded
• Mint: Oaxaca (look for the mint mark)
• Date: 1889

The front (obverse) shows a Phrygian liberty cap over a radiating sunburst with the word LIBERTAD. The back (reverse) shows the Mexican eagle facing forward, perched on a cactus and devouring a serpent, with the legend REPÚBLICA MEXICANA.

How much is it worth?

Value on this coin is driven by three things, in order: silver content, condition, and the specific mint-and-date combination. Because it is 90 percent silver, it can never be worth less than its melt value. That is the floor. Everything above that floor comes from collector demand for the grade and the mint mark.

Condition	What it looks like	Typical value (USD)
Heavily worn (Good to Fine)	Design flat, details soft	Melt value, roughly 20 to 30 USD
Circulated (Very Fine to XF)	Full design, honest wear	35 to 90 USD
About Uncirculated	Slight wear on high points	90 to 250 USD
Uncirculated (Mint State)	No wear, original luster	250 to 800+ USD

These are working ranges, not guarantees. The Oaxaca mint struck fewer of these than the big mints like Zacatecas or Mexico City, so a genuine, high-grade Oaxaca 1889 can pull toward the top of the scale or beyond when two collectors want it. A worn one, honestly, is a silver piece with some history and not much of a premium.

The "it must be worth thousands" myth

Most people who find one of these assume that a coin over 130 years old is automatically worth a fortune. It usually is not. Millions of 8 Reales were struck across Mexico in the 1800s, and plenty survive. Age alone adds almost nothing. What moves the price is genuine scarcity (a tougher mint or date), strong condition, and confirmed authenticity. A common date in worn shape is a bullion coin, priced by the ounce.

The flip side: because this design was so widely copied and counterfeited, both in period and today, a verified-genuine, high-grade example carries a real premium precisely because so many fakes exist.

How to check what yours is worth

1. Weigh and measure it. Use a jewelry scale and calipers. It should hit close to 27.07 grams and 39 millimeters. A coin that is light, oversized, or magnetic is a red flag. Genuine silver is not magnetic.
2. Find the mint mark and assayer initials. Oaxaca coins carry the O mint mark. The style of the engraving, mint, and assayer letters all matter to collectors and to spotting fakes.
3. Grade it honestly. Wear on the high points of the eagle and the cap tells you the grade. See the Pesoteca guide to coin grading to place yours on the scale above.
4. Get it authenticated if it looks high grade. If your coin appears uncirculated, it is worth having it certified by NGC or PCGS before selling. Certification separates a 300 USD coin from a fake.

This piece belongs to the broader 8 Reales silver series of the Mexican Republic, which is a good reference point for comparing other dates and mints you may have.

Where to sell it

Sell where the buyer shows you the coin and confirms the weight in front of you. A verified numismatic shop from the Pesoteca directory will appraise it on the spot with no middleman markup. For collector-to-collector deals, the Pesoteca buy-and-sell forum reaches people who understand what an Oaxaca 1889 is actually worth. Photograph the obverse, reverse, and edge before you list it, and check the range in this page first. Do not dump it to the first Facebook offer.

In 1889 Porfirio Diaz governed in the middle Porfiriato. Years of the 1889 Paris Universal Exposition with a Mexican pavilion and of the consolidation of the railroad as a pillar of the economy.

The Oaxaca mint (Oa) reopened in 1858 during the War of Reform to supply currency to the south. It closed in 1893 in the centralizing reform prior to the late Porfiriato.

Oa pieces are hunted by collectors of short-lived mints. The early closure (1893) makes years like 1892-1893 particularly scarce.

For catalog reference, the variant of this mint is listed as KM#377.11 in Krause. The piece is silver at .9028 fineness with a reeded edge and a theoretical weight of 27.07 grams. The 1889 Oaxaca specimen corresponds to the phase in the mature stage of the mint, near the closure (1858-1893), and is identified on the coin by the Oa mint mark.

To hunt down this Oa piece without overpaying, check both regional shows and professional auction listings. Specimens from the 1880s cycle in Oa have enough supply to compare edges, original luster, and pitting across 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 specimens presented as superior quality.
