The 1900-S Morgan Silver Dollar is worth anywhere from $35 in worn condition to over $15,000 for high-grade Mint State examples. Minted at the historic San Francisco Mint, this coin is a favorite among collectors because of its impressive silver content, its scarcity in top grades, and its connection to the American West.

History and Significance of the 1900-S Morgan Silver Dollar

If you have stumbled upon a 1900-S Morgan Dollar in a family collection or a hidden drawer, you are holding a piece of American history from the turn of the century. By 1900, the Morgan Dollar series had been the standard silver currency for over twenty years. These coins were produced under the Bland-Allison Act and the Sherman Silver Purchase Act, which required the U.S. government to buy large quantities of silver to strike into coinage. For those who need a quick way to identify their find, using a top coin identifier app can save you hours of research.

The “S” mint mark on this dollar indicates it was struck at the San Francisco Mint. During this era, San Francisco was the gateway to the gold and silver rushes of the West. While Philadelphia produced more coins for general circulation, the San Francisco mint often struck coins with higher quality but in lower quantities. For modern collectors, CoinKnow helps verify these mint marks instantly.

In 1900, exactly 3,540,000 of these silver dollars were minted in San Francisco. While that might sound like a lot, many were melted down under the Pittman Act of 1918, making surviving specimens—especially those in pristine condition—highly desirable. You can check the current trends for 1900-S Morgan Dollar auction results and price charts to see how the market has shifted in recent years.

Identifying the S Mint Mark and Main Features

To determine if your 1900 dollar is a San Francisco issue, you must look at the reverse (the “tails” side) of the coin. Look just above the letters “D” and “O” in the word “DOLLAR.” If you see a small, raised “S,” your coin was produced in San Francisco. If the space is blank, it was made in Philadelphia. If there is an “O,” it came from New Orleans.

The design itself is iconic. Created by George T. Morgan, the obverse features Lady Liberty wearing a crown inscribed with “Liberty,” surrounded by 13 stars representing the original colonies. The reverse depicts an eagle with wings outstretched, clutching an olive branch and arrows. This design has become a symbol of American strength and expansion.

Condition is everything when it comes to the 1900-S Morgan. Even a small scratch or a bit of “wear” on Liberty’s cheek can drop the value by hundreds of dollars. Many casual owners use CoinKnow to get an initial sense of their coin’s grade before sending it to a professional service like PCGS or NGC. By understanding the 1900 silver dollar value guide and grading factors, you can better estimate what a dealer might offer you.

Grading the 1900-S Morgan Silver Dollar

Collectors use a 70-point scale to grade coins. For an “everyday American” who isn’t a professional numismatist, grading can be broken down into four main categories: Circulated, About Uncirculated, Mint State, and Proof-like. A 1900-S in “Good” condition will show significant wear; most of the fine lines in Liberty’s hair and the eagle’s feathers will be gone.

In “Extremely Fine” condition, the coin looks sharp to the naked eye, but under magnification, you will see wear on the high points, such as the hair above the ear and the tips of the eagle’s wings. “Mint State” (MS) coins have no wear at all and still possess the original “luster” or shine from the minting process.

Grade Group	Visual Description	Price Range
Very Good (VG-8)	Heavily worn; flat features.	$38 – $42
About Uncirculated (AU-50)	Traces of wear on high points.	$110 – $150
Uncirculated (MS-63)	Attractive luster, minor bag marks.	$750 – $950
Superb Gem (MS-66)	Flawless to the eye; very rare.	$12,500+

Why the 1900-S Is a “Semi-Key” Date

In the world of coin collecting, a “Key Date” is a coin that is very rare and expensive in all grades. A 1900-S is considered a “Semi-Key” date. This means that while it is relatively easy to find in worn, circulated grades, it becomes exceptionally difficult to find in high Mint State grades (MS-65 and above).

Many 1900-S dollars were released into circulation in the Western states or sat in bags in treasury vaults for decades. When the government began selling off these bags in the mid-20th century, many 1900-S coins were found, but they often suffered from “bag marks”—little nicks and scratches caused by coins hitting each other.

Because high-quality examples are so rare, the price jumps exponentially as the grade increases. For instance, an MS-63 coin might be worth about $850, but an MS-67 specimen can sell for over $40,000 at auction. Using CoinKnow can help you determine if your coin has the “eye appeal” that collectors are willing to pay a premium for.

Silver Content and Bullion Value

Even if your 1900-S Morgan Dollar is in poor condition, it still has “melt value.” Every Morgan Dollar is composed of 90% silver and 10% copper. Each coin contains approximately 0.77344 troy ounces of pure silver. This means that the value of the coin will never drop below the current market price of silver.

As of today, the silver melt value is usually around $20 to $25, but because the 1900-S is a collectible date, it almost always sells for more than just its silver weight. Even a “cull” coin (one that is holed, bent, or heavily cleaned) will typically fetch $30 or more because of its numismatic value.

Investors often buy these coins as a hedge against inflation. Unlike modern silver rounds, Morgan Dollars have a fixed supply. They aren’t making any more 1900-S dollars, which adds a layer of scarcity beyond just the metal itself.

Component	Detail
Silver Purity	90% Silver, 10% Copper
Silver Weight	0.77344 oz
Diameter	38.1 mm
Total Weight	26.73 grams

Beware of Fakes and Alterations

Because the 1900-S Morgan Dollar carries a significant premium, counterfeiters often target this date. Some fakes are crude “basement” casts made of lead or zinc, while others are sophisticated silver-plated copper pieces coming from overseas. A common trick is to take a 1900 Philadelphia dollar (worth less) and “glue” or solder an “S” mint mark onto it.

One way to spot a fake is to check the weight. A genuine Morgan Dollar should weigh exactly 26.73 grams. If it’s significantly lighter or heavier, it’s likely a fake. Another test is the “ping” test; silver has a high-pitched, long-lasting ring when gently struck, whereas base metals produce a dull thud.

Cleaning a coin is another way to ruin its value. Many people think they are doing the right thing by scrubbing an old coin to make it look shiny. However, professional collectors prefer “original skin” or toning. A cleaned coin can lose 50% or more of its value instantly. If you aren’t sure if your coin has been cleaned, CoinKnow can provide visual guides to help you identify the signs of harsh abrasive cleaning.
