History and Background of the 1918-S Standing Liberty Quarter
The Standing Liberty Quarter series remains one of the most artistic and controversial designs in the history of the United States Mint. First released in late 1916, this coin replaced the long-running Barber design. By 1918, the United States was deeply involved in World War I, and the San Francisco Mint was working hard to produce enough silver coinage to keep the economy moving.
If you have stumbled upon an old silver coin and aren’t sure if it’s the real deal, using a top coin identifier app can help you confirm the date and mint mark within seconds. The 1918-S is particularly interesting because it represents the “Type 2” design, which added chain mail to Lady Liberty’s chest and adjusted the stars on the reverse side.
Collectors often look for the “S” mint mark, which signifies the San Francisco Mint. During this era, San Francisco coins often had lower survival rates in “Mint State” compared to those from Philadelphia. This scarcity means that while a worn 1918-S is accessible to most, a pristine version is a high-stakes investment for serious numismatists. Utilizing CoinKnow allows you to see social trends and how many people are currently searching for this specific date and mint mark.

How Much is the 1918-S Standing Liberty Quarter Worth Today?
Determining the exact value of your 1918-S quarter depends heavily on two factors: the physical condition and the presence of the “Full Head” detail. In low grades, where the date is just barely visible, the coin is still worth significantly more than its melt value in silver. While a common silver quarter might be worth only $5, the 1918-S maintains a premium due to its age and collector demand.
For those looking for accurate market data, the 1918-S Standing Liberty Quarter price charts show that middle-tier grades (Fine to Very Fine) are where most casual collectors find their coins. These pieces have clear numbers in the date but may lack the fine details in Liberty’s shield or gown.

The market for these coins is very liquid. If you list a 1918-S on a marketplace, it usually attracts bids quickly. However, to get top dollar, you must accurately assess whether the coin has been cleaned. Cleaned coins (those scrubbed with chemicals or abrasive cloths) lose up to 50% of their collector value. You can use the CoinKnow app to compare your coin’s luster to high-resolution images of original, uncleaned examples.
| Grade Designation | Retail Value (Approx.) |
|---|---|
| VG-8 (Very Good) | $40 – $50 |
| VF-20 (Very Fine) | $90 – $110 |
| AU-50 (About Uncirculated) | $350 – $425 |
| MS-63 (Mint State) | $800+ |
Understanding the Rare “Full Head” (FH) Designation
If you want to understand the true peaks of the 1918-S Standing Liberty Quarter value, you must learn about the “Full Head” (FH) designation. In the early 20th century, the striking pressure at the San Francisco Mint was sometimes inconsistent. This resulted in coins where Lady Liberty’s head lacked detail, looking like a smooth blob rather than a face with a distinct helmet and ear hole.
A coin that possesses all the sharp details—the horizontal lines of the hair, the ear, and the distinct outline of the helmet—is granted the FH designation by grading services like PCGS or NGC. A 1918-S with a Full Head can be worth five to ten times more than an identical coin without that sharp strike. For example, an MS-65 without FH might sell for $1,200, but a “Full Head” MS-65 can soar above $6,000.

Checking for this detail requires a magnifying glass or a high-resolution camera. The CoinKnow app provides a “Coin Recognition” feature that can help identify the sharpness of your coin’s strike. Beginners often mistake a shiny coin for a “Full Head” coin, but it is the deepness of the strike, not the shininess, that counts here. You can find more historical pricing for 1918-S FH quarters online to see how these premiums have grown over the last decade.
Identifying the 1918-S Mint Mark and Composition
The 1918-S Standing Liberty Quarter is made of 90% silver and 10% copper. Because of its silver content, it has an intrinsic “melt value” that fluctuates with the global silver market. However, you should never sell this coin for its weight in silver; the numismatic (collector) value is always higher than the silver value, even for worn pieces.
To find the mint mark, look at the front (obverse) of the coin. It is located just to the left of the date, next to the star. If you see a small “S”, it was minted in San Francisco. If there is no letter at all, it was minted in Philadelphia. If there is a “D”, it came from Denver. The 1918-S is generally more valuable than the 1918-P but less expensive than some of the extremely rare Denver dates in high grades.

The weight of a brand-new 1918-S quarter should be 6.25 grams. If your coin is significantly lighter, it may be due to heavy wear or, in rare cases, it could be a counterfeit. Always use a digital scale to verify the weight if you are buying an uncertified coin from a private seller.
| Specification | Details |
|---|---|
| Composition | 90% Silver, 10% Copper |
| Silver Weight | 0.18084 troy oz |
| Diameter | 24.3 mm |
| Total Mintage | 11,072,000 |
The Famous 1918/7-S Overdate Error
While the standard 1918-S is valuable, there is a legendary “error” coin from this year that every hunter dreams of finding: the 1918/7-S Overdate. This occurred when a 1918 die was accidentally impressed with a 1917 hub. The result is a coin where a “7” is clearly visible underneath the “8” in the date.
This is one of the most famous errors in 20th-century American numismatics. Even in very poor condition (G-4), a 1918/7-S overdate can be worth $1,000. In middle grades, it can fetch $3,000 to $8,000, and in high Mint State grades with a Full Head, it has been known to sell for over $100,000 at auction.
If you think you have found an overdate, do not try to clean the coin to see the date better. Cleaning will ruin the value. Instead, use a jeweler’s loupe or a high-quality smartphone camera to zoom in on the “8”. Look for the tail of the “7” protruding from the top left and middle of the “8”. Because these are so valuable, many fakes exist, so professional authentication is essential for this specific error.

Collecting Tips for the Standing Liberty Series
Starting a collection of Standing Liberty Quarters is an accessible hobby for most Americans, but the 1918-S is often a “milestone” coin for many. Because the dates on this series were “raised” in the original design, they tended to wear off very quickly in circulation. This is why many quarters from this era are found “dateless.”
A dateless 1918-S is essentially worth only its silver melt value (roughly $5), because without a visible date, it’s just a hunk of 90% silver to most collectors. When buying, always prioritize coins with a “bold” date. This ensures that the coin will retain its resale value over time.
For those curious about their collection’s total worth, keeping a digital inventory is key. Use tools like CoinKnow to track your coins and receive alerts when market prices for the 1918-S shift. This helps you decide whether to hold onto your treasure as an investment or sell it when the market is hot.
FAQ
Q: Why is my 1918-S quarter so worn?
A: The design of the Standing Liberty Quarter had a flaw where the date was placed on a high point of the coin. This meant that the date was the first thing to rub off as the coin changed hands in daily commerce. Most 1918-S quarters found today are in “Good” or “Very Good” condition for this reason.

Q: Is there any gold in a 1918-S quarter?
A: No, the coin is composed of 90% silver and 10% copper. While some may appear yellowish due to “toning” (oxidation), they do not contain any gold.
Q: Where is the mint mark on a 1918-S quarter?
A: The “S” mint mark is located on the front (obverse) of the coin, just to the left of the date and slightly above it, near Lady Liberty’s right foot (your left).
Q: Should I get my 1918-S Standing Liberty Quarter graded?
A: If your coin appears to be in “About Uncirculated” or “Mint State” condition, or if it is the 1918/7-S overdate error, you should definitely have it graded by a professional service like PCGS or NGC. If it is heavily worn, the cost of grading might exceed the value of the coin.
