The Story Behind the 1918/7-S Overdate Error
If you’ve discovered an old quarter featuring a goddess holding a shield, you might be holding a piece of history. Finding this specific coin is like winning the lottery for coin hunters. The 1918/7-S overdate occurred at the San Francisco Mint when a 1917-dated hub was used to create a 1918 die. This resulted in the number “8” being stamped directly over the “7,” a mistake that wasn’t noticed until these coins were already in circulation.
Because this error was caught late, most of these coins were used in daily transactions for decades. If you aren’t sure what you’re looking at, using a top coin identifier and value app can help you zoom in on the date to see if the “7” is visible beneath the “8.” Finding one in your grandfather’s old jar is rare, but it happens more often than you’d think.
The rarity of this coin stems from the fact that it is a “Variety,” not just a standard issue. While millions of quarters were made in 1918, only a tiny fraction featured this specific overdate. CoinKnow helps users distinguish between the common 1918-S and this high-value overdate by providing high-resolution comparison photos for hobbyists.

How to Identify a Genuine 1918/7-S Standing Liberty Quarter
Identifying this coin requires a sharp eye or a good magnifying glass. Look closely at the last digit of the date. You should see the top bar of a “7” protruding from the top of the “8,” and the diagonal tail of the “7” visible inside the bottom loop of the “8.” If the date is too worn to see, the coin’s value drops significantly, but it remains a prized collector’s item.
Collectors also look for the “S” mint mark, located just to the left of the date, near the star. This indicates the coin was struck in San Francisco. Because this coin is so valuable, counterfeits do exist. Many people use CoinKnow to verify the placement of the mint mark and the specific “die markers” that prove a coin is authentic before taking it to a professional dealer.

Another key identification factor is the “Full Head” (FH) designation. On the Standing Liberty Quarter, the detail on Lady Liberty’s helmet and hair is the first thing to wear away. A coin with a “Full Head” detail is exponentially more valuable than one where the hair is smooth. Check the 1918 quarter value guide for visual examples of what a Full Head strike looks like.
Grading and Condition: Why It Matters
In the world of coin collecting, condition is everything. A 1918/7-S quarter that has been jingling in pockets for twenty years will be “Circulated,” while one that was tucked away in a safe immediately is “Uncirculated.” The difference in price between these two states can be tens of thousands of dollars.

Numerical grading ranges from 1 to 70. A grade of G-4 (Good) means the coin is very worn but the date is readable. An MS-65 (Mint State) grade means the coin looks exactly as it did the day it left the mint. You can find the latest current price data for 1918/17-S MS condition quarters to see how much of a premium high-grade examples command.
| Condition | Detailed Description | Price Range |
|---|---|---|
| About Good (AG-3) | Date is barely legible, rim is worn into design. | $800 – $1,100 |
| Very Fine (VF-20) | Liberty’s drapery is worn but clear; date is bold. | $5,000 – $6,800 |
| About Uncirculated (AU-50) | Slight wear on high points; some mint luster remains. | $15,000 – $22,000 |
What Makes the “Full Head” (FH) Designation Special?
You will often see the letters “FH” following the grade of a Standing Liberty Quarter. This stands for “Full Head.” To earn this designation, Lady Liberty’s head must show full detail, specifically the three leaves in her hair and the distinct line of her helmet. Because this coin was notoriously difficult to strike clearly, very few 1918/7-S quarters possess this level of detail.
An MS-63 without a Full Head might sell for $25,000, but that same coin with a Full Head could easily fetch $80,000 or more. This makes the coin a favorite for high-end investors. If you suspect your coin has this level of detail, CoinKnow’s identification features can help you compare your coin to certified FH examples held in museums and private collections.

Even in lower grades, the eye appeal matters. A coin with nice “toning” (natural coloration from age) will often sell for more than one that is dull or scratched. Professional grading by services like PCGS or NGC is highly recommended for this particular coin because of the massive price swings based on tiny details.
Real World Auction Records and Market Trends
The market for rare coins like the 1918/7-S has remained incredibly strong, even during economic downturns. Rare “key dates” and “overdates” are seen as “hard assets.” In recent years, high-quality specimens have repeatedly broken records at auction houses like Heritage Auctions and Stacks Bowers.
For example, a 1918/7-S graded PCGS MS-64+ FH recently sold for over $100,000. Even common “Fine” condition pieces have seen a steady 5-10% price increase year-over-year. This is because the number of surviving pieces is fixed, while the number of collectors entering the market continues to grow.

Tips for Selling Your Rare Quarter
If you are lucky enough to find a 1918/7-S, do not clean it! Cleaning a rare coin can strip away its surface luster and reduce its value by 50% or more. Instead, handle the coin only by its edges and place it in a protective PVC-free plastic holder or a cardboard “2×2” flip.
The first step in selling is getting the coin authenticated. Because of its high value, no reputable dealer will buy it without a “slab” (a protective plastic case with a certified grade) from PCGS or NGC. You can use CoinKnow to find reputable local dealers or auction houses that specialize in Standing Liberty Quarters.
When you’re ready to sell, consider an auction if your coin is in high grade (VF or better). Auctions create competition between buyers, which can drive the price higher than a direct sale to a local coin shop. For lower-grade examples, a direct sale might be faster and easier.
FAQ
Q: Why is the 1918/7-S so much more valuable than a regular 1918 quarter?
A: The 1918/7-S is an “overdate” error rarity. While several million 1918 quarters were minted, only a very small number were struck using the 1918-over-1917 die. This rarity, combined with high demand from collectors trying to complete a full set of Standing Liberty Quarters, drives the price into the thousands.

Q: Can I find a 1918/7-S in pocket change today?
A: It is extremely unlikely to find one in modern pocket change because silver quarters were phased out of circulation in 1964. However, they are frequently found in “unsearched” estate coin collections, inherited jars of old coins, or through metal detecting in historic areas.
Q: What is the “Type 2” design and does it affect the 1918/7-S?
A: The Standing Liberty Quarter had two main designs. Type 1 (1916-1917) showed Lady Liberty with an exposed breast. Type 2 (1917-1930) added chain mail to her chest and moved the stars on the reverse side. All 1918/7-S quarters are the “Type 2” design.
Q: I found a 1918-S quarter but I can’t see the “7” under the “8.” Is it still valuable?
A: Yes, a standard 1918-S (San Francisco) quarter is still worth money because it is 90% silver and over 100 years old. However, without the overdate error, its value is significantly lower—usually ranging from $15 to $200 depending on condition, rather than the thousands of dollars the overdate commands.
