History and Identifying the 1918-S Walking Liberty Half Dollar

The Walking Liberty Half Dollar series began in 1916 and lasted until 1947, designed by the talented sculptor Adolph A. Weinman. In 1918, the United States was deeply involved in World War I, and coins were needed to fuel the domestic economy. The San Francisco Mint produced just over 10 million of these coins, which sounds like a lot, but very few have survived in good condition after over a century of circulation.

To identify if your 1918 half dollar was made in San Francisco, you must look for the “S” mint mark. On the 1918 issue, the mint mark is located on the reverse (the back) of the coin, near the rim at the bottom left, just below the eagle’s trailing wing. If there is no letter there, it was minted in Philadelphia. If there is a small “D,” it came from Denver. The San Francisco “S” version is particularly prized by collectors because it often features strike weaknesses that make high-grade examples extremely rare.

Understanding the Value of Circulated 1918-S Half Dollars

Most 1918-S half dollars found today are in “circulated” condition, meaning they sat in people’s pockets and were used to buy groceries or movie tickets decades ago. A coin in “Good” or “Very Good” condition will show significant wear, with Lady Liberty appearing almost like a silhouette and the eagle on the back missing most of its feather detail. These heavily worn coins are still valuable because of their silver content and historical appeal, typically selling for $15 to $35.

As the condition improves to “Fine” or “Very Fine,” you will start to see the lines in Liberty’s dress and the branches in her hand more clearly. At these levels, the 1918-S Walking Liberty Half Dollar market price begins to climb significantly, often reaching $60 to $150. For the average person, determining the exact grade can be tricky, which is where the CoinKnow app becomes a lifesaver by providing visual comparisons to help you see where your coin falls on the grading scale.

A Full Guide to 1918-S Walking Liberty Half Dollar Prices

Determining the exact worth of your coin requires looking at the “Grade,” which is a numerical scale from 1 to 70 used by professional coin authenticators. Below is a detailed breakdown of what you can expect to receive for a 1918-S half dollar based on its condition.

Condition Grade	Descriptive Quality	Estimated Value
G-4 (Good)	Heavily worn, flat details	$15 – $22
F-12 (Fine)	Moderate wear, some lines visible	$40 – $65
VF-20 (Very Fine)	Light wear on high points	$110 – $160
EF-40 (Extremely Fine)	Sharp details, very little wear	$350 – $500
AU-50 (About Uncirculated)	Traces of wear, original luster	$800 – $1,200
MS-63 (Mint State)	No wear, brilliant shine	$4,500 – $6,500

What Makes a 1918-S Half Dollar Rare and Expensive?

The primary factor that drives the price sky-high is the “Mint State” or “Uncirculated” condition. Because 1918 was a year of war and economic hardship, almost every coin that left the San Francisco Mint went straight into circulation. People didn’t think to save them as collectibles. Consequently, finding a 1918-S that still looks as fresh as the day it was minted is incredibly difficult. For more specific details on why certain years vary, you can check this 1918 half dollar value assessment for deeper insights into the rarity of the “S” mint mark compared to others.

Another factor is the “strike” quality. The San Francisco Mint in 1918 was known for having slightly worn-out or oily dies, which resulted in coins that sometimes look “soft” or blurry even if they haven’t been circulated. Collectors pay a massive premium for a 1918-S that has a “sharp strike,” where Lady Liberty’s hand and the eagle’s breast feathers are crisp and well-defined. If you suspect your coin is uncirculated, you should definitely use CoinKnow to compare it with high-resolution photos of museum-quality specimens.

How to Sell and Protect Your Silver Half Dollar

If you have determined that your coin is worth more than just its weight in silver, it is crucial to handle it properly. Never clean your coins! Cleaning a 1918-S Walking Liberty Half Dollar with polish or a cloth can instantly destroy up to 50% of its collector value by creating tiny scratches on the surface. Collectors prefer a natural, aged “patina” or toning over a fake, scrubbed shine.

To sell your coin, your first step should be taking clear, well-lit photos. You can then use a valuation tool to get a ballpark figure. If the coin is in exceptionally good condition (looking almost new), it might be worth sending it to a professional grading service like PCGS or NGC. These third-party authenticators will “slab” the coin in a protective plastic holder and give it an official grade, which makes it much easier to sell for a fair market price to dealers or through online auctions.

1918-S Walking Liberty Half Dollar FAQ

Q: Is the 1918-S Walking Liberty Half Dollar made of real silver?

A: Yes, all Walking Liberty Half Dollars minted between 1916 and 1947 are made of 90% silver and 10% copper. Each coin contains approximately 0.3617 ounces of pure silver, meaning they have a “melt value” that fluctuates with the price of silver bullion.

Q: Where is the mint mark on a 1918-S half dollar?

A: On the 1918-S, the “S” mint mark is found on the reverse side. Look at the lower left area of the coin, near the rim, just below the eagle’s wing. If you see an “S,” it was minted in San Francisco.

Q: Why is my 1918-S coin so blurry or soft looking?

A: The San Francisco Mint often struggled with the strike quality during this era. Many 1918-S coins were “weakly struck,” meaning the details weren’t fully pressed into the metal. This is common and doesn’t always mean the coin is worn down; however, coins with a “sharp strike” are much more valuable.

Q: How can I tell if my coin is worth thousands of dollars?

A: For a 1918-S to be worth thousands, it must be in “Mint State” condition, meaning it has absolutely no wear on the highest points of Lady Liberty’s breast, leg, or the eagle’s head. It should also have its original “mint luster”—the satiny shine found on new coins. If it looks shiny because someone cleaned it, it is likely only worth the silver value or a small collector premium.
