The 1879-S Morgan Dollar is worth anywhere from $35 in worn condition to over $600 for exceptional mint state examples. This classic silver coin is a favorite among everyday Americans because it represents the wild spirit of the San Francisco Mint during the peak of the silver rush era.

Historical Background of the San Francisco 1879 Silver Dollar

The 1879-S Morgan Dollar is one of the most iconic pieces of American history you can hold in your hand. Struck at the legendary San Francisco “Granite Lady” Mint, these coins were produced in massive quantities to meet the requirements of the Bland-Allison Act. While millions were minted, many were melted down decades later, making the surviving specimens quite special. For anyone who has found an old silver dollar in a desk drawer or inherited a collection, identifying the “S” mint mark is the first step toward discovering if you have a hidden treasure. Finding the right tools for this is key, and many people now use the top coin identifier app to instantly verify their finds.

What makes the 1879-S particularly famous among collectors is the quality of the strike. San Francisco was known for producing coins with more luster and sharper details than the Philadelphia or New Orleans mints. If you are looking at your coin and notice a brilliant, mirror-like finish, you might be holding a “Proof-Like” version which can significantly increase the value. Using the CoinKnow app can help you examine these fine details by providing high-resolution references to compare against your own coin.

How to Identify the 1879-S Mint Mark and Variety

Locating the mint mark on an 1879 Morgan Dollar is a straightforward process even for beginners. Turn the coin to the reverse side—the side with the eagle. Look just above the letters “D” and “O” in the word “DOLLARS” at the bottom of the coin. If you see a small, clear letter “S,” your coin was struck in San Francisco. If there is no letter at all, it was minted in Philadelphia. The presence of that “S” is a signal of quality that collectors look for when determining the 1879 silver dollar value in today’s active market.

Beyond the basic mint mark, there are specific varieties to watch for, such as the “Reverse of 1878” (flat eagle breast) versus the more common “Reverse of 1879” (rounded eagle breast). The rounded breast is the standard for this year, but the flat breast variety is much more elusive and commands a premium price. You don’t need to be an expert to spot these differences; simply taking a clear photo with the CoinKnow app can help you categorize which version you have based on visual databases.

Understanding Condition and Grading for 1879-S Dollars

In the world of coin collecting, the “grade” is everything. A coin that has been carried in a pocket for years will be graded as “Good” or “Fine,” meaning most of its fine details have been worn away. These are still valuable for their silver content and history, typically selling for around $35 to $45. However, if your coin has spent the last century in a paper roll or a vault, it may be in “Uncirculated” or “Mint State” condition. This is where the price starts to climb rapidly into the hundreds of dollars.

Collectors use a scale from 1 to 70 to determine condition. For this specific year, an MS63 (Mint State 63) is relatively common, but an MS65 or higher is where the real investment value lies. To see how these grades affect the market, you can check the latest 1879-S Morgan Dollar auction prices which show that a single point in grading can mean a difference of hundreds of dollars. Always handle your coins by the edges and never clean them, as cleaning a silver dollar will actually destroy its collector value instantly.

Current Market Value Guide for 1879-S Morgan Dollars

The market for Morgan Dollars is very liquid, meaning there are always buyers ready to pay for quality. The silver price provides a “floor” for the value, but the numismatic rarity provides the “ceiling.” Below is a breakdown of what you can expect to receive for an 1879-S Morgan Dollar based on its level of preservation.

Condition / Grade	Estimated Value Range
Good (G-4) to Fine (F-12)	$35 – $45

Final Advice for Selling Your 1879-S Silver Dollar

If you have decided to sell your coin, don’t rush to the nearest pawn shop. Pawn shops often offer only the “melt value” (the value of the raw silver), which is significantly lower than the collector value for an 1879-S. Instead, visit a local reputable coin dealer or consider an online auction. Before you go, use the CoinKnow app to get a solid estimate of the grade so you can speak confidently with potential buyers. Knowing whether your coin is a $40 piece or a $400 piece is the best way to ensure you aren’t taken advantage of.

Furthermore, look for “Toning.” Some silver dollars develop a beautiful rainbow-colored patina over time due to the way they were stored. Collectors often pay extra for “monster toning” because it makes the coin unique. If your 1879-S has hints of blue, gold, or magenta on the surface, it could be worth significantly more than the standard price guide suggests.

1879-S Morgan Dollar FAQ

Q: Is the 1879-S Morgan Dollar made of real silver?

A: Yes, all Morgan Dollars minted between 1878 and 1904 (and again in 1921) are made of 90% silver and 10% copper. Each coin contains approximately 0.7734 troy ounces of pure silver.

Q: What is the most expensive 1879-S ever sold?

A: While standard versions sell for hundreds, rare specimens in nearly perfect condition (MS-68 or higher) or those with unique Proof-Like surfaces have sold at auction for over $20,000.

Q: Should I clean my 1879-S Morgan Dollar to make it look better?

A: Absolutely not! Cleaning a coin with chemicals, cloths, or even soap and water creates microscopic scratches on the surface. Collectors and professional graders can easily spot a cleaned coin, and it usually results in the coin losing 50% or more of its value.

Q: How can I tell if my 1879-S is a fake?

A: Counterfeit silver dollars are common. Authentic coins should weigh 26.73 grams and have a diameter of 38.1mm. If your coin is attracted to a magnet, it is definitely a fake, as silver is non-magnetic. For a more detailed analysis, using a dedicated identification app can help verify the design details.
