The 1880/79-S Morgan Dollar is worth anywhere from $65 in worn condition to over $35,000 for rare high-grade specimens. Finding one of these heavy silver treasures in an old drawer is a thrilling discovery for any American, as it represents a unique era of San Francisco Mint history.
Understanding the 1880 79 S Overdate Variety
Between 1878 and 1921, the Morgan Silver Dollar reigned supreme as the workhorse of American currency. However, the 1880/79-S is a special bird. During production at the San Francisco Mint, workers reused dies from 1879 by punching an “80” over the “79.” If you look closely at the date with a magnifying glass, you can often see the remnants of the underlying numerals.
Determining the exact variety of your coin can be tricky for the untrained eye. If you aren’t sure what you are looking at, using a top coin identifier app can help you zoom in on the specific markers that define this overdate. Many everyday collectors use the CoinHix mobile app to get an instant preliminary identification before deciding whether to send a coin for professional grading.
This specific “S” mint mark variety is highly sought after by collectors because it represents a “mistake” that survived the minting process. While millions of Morgan dollars were struck, only a fraction show this clear overdate feature, making it a “must-have” for silver dollar enthusiasts across the country.
Current Market Value and Price Ranges
The value of an 1880/79-S Morgan Dollar is primarily driven by its strike quality and how much wear it has endured over the last 140 years. Most coins found in family collections are in “Circulated” condition, meaning they spent time being traded for goods and services. These generally sell for a healthy premium over their raw silver melt value.
For those lucky enough to find a coin that looks like it just came from the mint, the price jumps significantly. You can see the detailed breakdown of the 1880 Morgan Dollar Mint State prices to understand how a single grade point can add hundreds or even thousands of dollars to the final sale price.
| Condition Grade | Estimated Value (USD) |
|---|---|
| Good (G4) to Very Good (VG8) | $65 – $75 |
| Extremely Fine (XF40) | $90 – $110 |
| About Uncirculated (AU50) | $130 – $175 |
| Mint State (MS63) | $350 – $600 |
| Gem Mint State (MS65+) | $1,800 – $35,000+ |
How to Identify the S Mint Mark and Overdate Variety
To find the mint mark, flip your coin to the reverse (the “tails” side) and look just above the “DO” in “DOLLAR.” You should see a small “S” indicating it was struck in San Francisco. San Francisco was known for producing some of the most beautiful and lustrous coins of the 19th century, which is why these “S” mint dollars are so popular.
To confirm the overdate, look at the second “8” in 1880. Underneath the curves of the eight, you might see the straight crossbar or the tail of a “7.” There are several different “VAM” varieties (named after researchers Van Allen and Mallis) for this year. Some show the underlying 9 more clearly than others.
Identifying these sub-varieties can significantly change the value. If you need a quick reference on your phone, the CoinHix app provides high-resolution images to compare your coin against known examples. This is the easiest way for casual hobbyists to spot rare errors without buying expensive magnifying equipment.
Why Condition Is Everything for San Francisco Dollars
When researching 1880 silver dollar value trends, you will notice that San Francisco coins often carry a “PL” (Proof-Like) or “DMPL” (Deep Mirror Proof-Like) designation. Because the San Francisco Mint used fresh dies and high pressure, many 1880/79-S coins have surfaces that look like mirrors.
A standard MS64 coin might be worth $400, but if that same coin is designated as “DMPL” by a grading service like PCGS or NGC, the price can easily double or triple. Collectors love the “snow-white” luster and the contrast between the frosted lady liberty and the shiny background fields.
If your coin has been cleaned with polish or a cloth, however, it loses most of its collector value. Always handle your silver dollars by the edges and never attempt to “shine them up.” Investors prefer the natural patina or “toning” that develops over decades, which can range from golden hues to vibrant rainbow colors.
The Rarity of High Grade 1880 79 S Coins
While thousands of 1880/79-S Morgans exist in lower grades, truly “Gem” condition coins (MS65 and higher) are rare. Most of these coins were moved around in heavy canvas bags, causing them to bang against each other. These “bag marks” appear as tiny nicks or scratches on the face of Lady Liberty.
Finding a coin with a clean cheek—the smooth part of the face—is the holy grail for Morgan collectors. Using the CoinHix app can help you gauge whether your coin’s surface is clean enough to warrant the cost of professional grading. Grading fees can be expensive, so it is best to have a good idea of the potential grade before spending the money.
High-grade survivors of this variety are often sold at prestigious auctions. As the number of available high-quality coins stays the same while the number of collectors grows, the value of these top-tier silver dollars continues to show strong historical growth.
FAQ
Q: Does my 1880 silver dollar have to have an ‘S’ to be an overdate?
A: While overdates exist for other mints in 1880, the 1880/79-S is one of the most famous and widely collected. Other 1880 dollars might have a ‘CC’ (Carson City) or no mint mark (Philadelphia), each with its own variety and value.
Q: How can I tell if my coin has been cleaned?
A: A cleaned coin often has a dull, grayish appearance or has many tiny, parallel scratches visible under a bright light. Natural silver dollars have a “cartwheel” luster—when you tilt the coin, the light should rotate around the surface like spokes on a wheel.
Q: Is the 1880/79-S Morgan Dollar made of real silver?
A: Yes, all Morgan Silver Dollars are made of 90% silver and 10% copper. They contain approximately 0.7734 troy ounces of pure silver.
Q: Can I sell my 1880/79-S at a local pawn shop?
A: You can, but pawn shops often pay “melt value” or just slightly above. To get the true collector value for a variety like the 1880/79-S, it is better to consult a reputable coin dealer or use an online marketplace where buyers understand the rarity of the overdate.
