The 1918-S Walking Liberty Half Dollar is worth anywhere from $20 in heavily worn condition to well over $1,000 or more in higher mint state grades. If you found one of these silver coins in an old collection or tucked away in a drawer, you may be sitting on something genuinely valuable — and this guide will help you figure out exactly what you have.
What Makes the 1918-S Walking Liberty Half Dollar Special
The Walking Liberty Half Dollar series ran from 1916 to 1947 and is widely considered one of the most beautiful coin designs in American history. Designed by Adolph A. Weinman, the obverse shows Lady Liberty draped in the American flag, striding confidently toward the sunrise. The reverse features a proud bald eagle perched on a mountain cliff.
The “S” mintmark on this coin tells you it was struck at the San Francisco Mint. In 1918, the San Francisco facility produced 10,282,000 of these half dollars — a decent mintage, but not so large that all examples survived in good shape. Many of these coins circulated heavily during their time, meaning finding a well-preserved specimen today is rarer than you might expect.

How Much Is the 1918-S Walking Liberty Half Dollar Worth
Value depends almost entirely on condition. A coin that’s been passed hand to hand for decades will show wear on the high points — Liberty’s hand, the eagle’s breast feathers — and that wear dramatically affects price. Coins in lower circulated grades (G-4 to VG-8) typically sell for $20 to $40. Move up to Fine or Very Fine, and you’re looking at $50 to $150.
The real excitement starts in Extremely Fine (EF-40) and About Uncirculated (AU) grades, where values can range from $175 to $400. If you’re lucky enough to have a Mint State coin, values jump considerably.

Silver Content and Intrinsic Value
One thing many people overlook is that the 1918-S Walking Liberty Half Dollar is made of 90% silver. Each coin contains approximately 0.3617 troy ounces of pure silver. That means even a beat-up, heavily worn example has real melt value based on the current silver spot price.
With silver frequently trading above $25 per ounce, the base metal value alone is often $9 to $10 or more. So even if your coin isn’t in great shape, it’s never truly worthless.
For a complete look at the full 1918 Half Dollar value including all mint marks and grades, it’s worth comparing Philadelphia, Denver, and San Francisco versions side by side. The “S” mint coin holds its own competitively throughout most grade ranges.
How to Get the Most Accurate Value for Your Coin
Grading coins takes practice, and it’s easy to overestimate or underestimate a coin’s condition at home. If you think you have something valuable, consider downloading CoinKnow — it’s a smart, user-friendly app that helps you identify coins, understand their grades, and get realistic current market estimates right from your phone.
CoinKnow is particularly useful for beginners who are sorting through old family coin collections or estate finds. Instead of guessing, you can scan and identify coins instantly, then look up their values based on current market data.
For coins in higher grades, professional third-party grading from PCGS or NGC will add credibility and often increase resale value significantly. A certified MS-63 or MS-65 example will always sell for more than a raw coin of the same quality.
FAQ
Q: How do I find the mintmark on a 1918 Walking Liberty Half Dollar?
A: On 1918 coins, the mintmark is located on the obverse (front) of the coin, just below the “IN GOD WE TRUST” motto on the left side. An “S” means San Francisco, “D” means Denver, and no mintmark means it was struck in Philadelphia.
Q: Is the 1918-S Walking Liberty Half Dollar rare?
A: With over 10 million struck, it’s not considered rare in circulated grades. However, finding one in Mint State condition — especially MS-64 or higher — is genuinely scarce, and those examples command strong premiums from serious collectors.
Q: Should I clean my 1918-S Walking Liberty Half Dollar before selling it?
A: Absolutely not. Cleaning a coin almost always destroys its numismatic value, leaving behind hairline scratches that experienced dealers and graders can immediately spot. A naturally toned, unclean coin will always be worth more than a cleaned one in the same underlying condition.
