1887 Mexico 8 Reales (Silver "Resplandor" / Cap and Rays)

If you inherited an 1887 Mexican 8 Reales, here is the honest answer first: this is a real 0.900 silver coin, so it has a built-in floor of roughly USD 25 to USD 30 in melt value at current silver prices, no matter how worn it is. A common, circulated example trades in the USD 30 to USD 60 range. Scarce mint marks and high-grade pieces can reach several hundred dollars. Coins in the thousands are the exception, not the rule.

This is the classic Mexican silver dollar of the 19th century, known to collectors as the "Cap and Rays" type, or Resplandor in Spanish (the word means "radiance," referring to the sunburst on the front). In 2026 it remains one of the most recognized and most counterfeited world silver coins, which is exactly why you should verify weight and diameter before you buy or sell.

What you actually have

The 1887 8 Reales is part of the long-running Mexican Republic silver series struck from 1824 into the early 1900s. The specifications are fixed and easy to check at home:

Spec	Value
Denomination	8 Reales
Year	1887
Metal	Silver, .900 fine (0.9028 standard)
Weight	27.07 grams
Diameter	39 mm
Edge	Reeded
Silver content	approx. 0.786 troy oz (24.4 g pure)

Front (obverse): A Phrygian cap (the "liberty cap") over a sunburst of rays, with the word LIBERTAD ("liberty"). This is the design that gives the coin its Resplandor nickname.

Back (reverse): The Mexican eagle facing forward, perched on a cactus and devouring a serpent, with the legend REPÚBLICA MEXICANA. Below the eagle you will find the mint mark and the assayer's initials, which matter a lot for value (more on that below).

What drives the value

Age alone is not the point. Millions of these were struck across many mints, so a worn common example is worth close to its silver. What actually moves the price:

1. The mint mark. Mexico ran multiple mints in 1887. Look at the small letters under the eagle. Common outputs like Mo (Mexico City), Zs (Zacatecas) or Ho (Hermosillo) are affordable. Scarcer mints such as Ca (Chihuahua), Cn (Culiacán), Do (Durango), Ga (Guadalajara), Go (Guanajuato), Oa (Oaxaca) or As (Alamos) can carry real premiums depending on the year and surviving numbers.

2. Grade (condition). A coin that spent decades in circulation is smooth and low-value. One with sharp eagle feathers, full liberty-cap detail and original luster jumps into collector territory. Certified Mint State examples (graded MS by NGC or PCGS) are where the strong money is.

3. Silver spot price. Because the coin is nearly 0.79 oz of silver, its value never falls below melt. When silver climbs, the floor climbs with it.

Honest range for the 1887 8 Reales: common mint, circulated: roughly USD 30 to USD 60. Better grade, common mint: USD 75 to USD 200. Scarce mint mark or certified Mint State: several hundred to well over USD 1,000 in the best combinations. The eye-popping five-figure prices you may have seen belong to specific rare-date, rare-mint, top-grade coins, not to a typical inherited piece.

The myth to ignore

A lot of online listings tag any 19th-century Mexican silver coin as "rare" and price it in the thousands. Most are not rare. The Cap and Rays 8 Reales was the workhorse trade coin of its era and was made in enormous quantities, some of it even shipped to Asia for commerce. If yours is worn and from a common mint, price it against silver, not against a fantasy headline.

How to check what yours is worth

1. Weigh it. Use a jewelry scale. A genuine coin lands very close to 27.07 grams. Well off that number is a red flag.
2. Measure it. A caliper should read about 39 mm across, with a reeded (grooved) edge.
3. Read the mint mark and assayer under the eagle. Note both letters.
4. Judge the wear. Compare the eagle's feathers and the cap detail against high-grade reference photos. Use the Pesoteca coin grading guide to place your coin on the scale.
5. Get it authenticated if the weight, mint or grade suggest real value. Counterfeits of this type are common, including cast fakes and modern restrikes, so a coin that is worth more than melt is worth verifying.

Where to sell it

For the best price without a middleman markup, use a verified numismatic dealer from the Pesoteca directory, where you can get an in-person appraisal, or list it in the Pesoteca buy-and-sell forum among collectors. Photograph the obverse, reverse and edge in good light, and check the range on this page before you agree to anything. Because this is a precious-metal coin, only deal with a buyer who will inspect and weigh the piece in front of you. Avoid dumping it on social media to the first offer.

Not sure what your mint mark is telling you, or whether that ding is a real strike error or just damage? Post clear photos of both sides in the Pesoteca forum and let the community weigh in.

In 1887 Porfirio Díaz was in office in his second consecutive term. Years of railway expansion (Mexico City-Ciudad Juárez, Mexico City-Laredo) and of the consolidation of foreign capital in mining and industry.

The Mexico mint (Mo) is the oldest on the American continent, founded in 1535. It was the main producer of hard pesos of the Republic and operated continuously until 1929 when it closed for good.

The 8 reales Mo have the highest mintages of the family, which makes them the gateway to the type. Good MS grades are more attainable here than at outlying mints.

As a catalog reference, the variant of this mint is listed as KM#377.10 in Krause. The piece is silver of .9028 fineness with a reeded edge and a theoretical weight of 27.07 grams. The 1887 Mexico (Mo) example corresponds to the mature stage of the mint, near its close (1535-1929), and is identified on the coin by the mint mark Mo.

When hunting 8 reales resplandor of Mo, it is best to compare with the photographic reference of the Pesoteca catalog and to prioritize examples with a legible reverse (eagle, serpent, legend REPÚBLICA MEXICANA and value 8R) over pieces with only a bright obverse. The peer-to-peer price among collectors of the 1880s cycle is usually more honest than the shop window of a specialized store, where the middleman markup can double the real reference.
