History of the 1928-S Walking Liberty Half Dollar
The Walking Liberty Half Dollar is widely considered the most beautiful silver coin ever minted by the United States. Designed by Adolph A. Weinman, it debuted in 1916 and continued through 1947. The 1928-S issue holds a special place in history because it was produced during a period of slowing economic momentum just before the Great Depression.
If you have found one of these in an old cigar box or inherited a collection, using a top coin identifier app can help you confirm if you have the genuine “S” mint mark version from San Francisco. In 1928, only the San Francisco Mint produced half dollars; the Philadelphia and Denver mints took a year off from this denomination.
This makes the 1928-S a “semi-key” date. While it is common in heavily circulated grades, it becomes exceptionally difficult to find in high-quality, uncirculated condition. Many of these coins were used in daily commerce for decades, wearing down the intricate details of Lady Liberty’s gown and the eagle’s feathers. Using CoinKnow allows you to scan your coin and compare it against thousands of high-resolution images to see where yours fits in history.

Identifying the Mint Mark and Silver Content
Before you get excited about the price, you need to verify two things: the mint mark and the silver content. All Walking Liberty Half Dollars minted in 1928 were struck at the San Francisco Mint. You can find the small “S” mint mark on the reverse side of the coin, located near the rim at the bottom left, below the eagle’s olive branch.
Every 1928 half dollar is made of 90% silver and 10% copper. This gives the coin an intrinsic “melt value” that acts as a price floor. Even if the coin is so worn that the date is barely visible, it will always be worth at least its weight in silver. However, because of the 1928-S rarity, it almost always sells for a premium above the silver price.

Grading Personal 1928-S Walking Liberty Half Dollars
Grading is the process of determining a coin’s physical condition, which is the single most important factor in its valuation. For the 1928-S, the jump in price between “Very Fine” and “Uncirculated” is massive. In lower grades, Liberty’s skirt lines and the branches she carries are blurred. In higher grades, you should see crisp lines on her sandals and individual feathers on the eagle.

| Grade Name | Visual Description |
|---|---|
| Good (G) | Rims are flat; Liberty is a silhouette with no drapery lines. |
| Fine (F) | Some drapery lines show; the eagle’s breast is flat. |
| Very Fine (VF) | Clear details on the gown; 75% of the eagle’s feathers are visible. |
| About Uncirculated (AU) | Slight wear only on the highest points like the breast and knee. |
Since the 1928-S was often “weakly struck,” even some uncirculated coins might look a bit flat in the center. This is why professional grading by services like PCGS or NGC is highly recommended for high-value specimens. You can use the CoinKnow community features to ask expert hobbyists for their opinion on your coin’s potential grade before spending money on professional certification.
Why the 1928-S is So Valuable in High Grades
The reason for the high 1928-S Walking Liberty Half Dollar value in Mint State is a combination of low mintage and poor preservation. In 1928, the San Francisco Mint produced only 1,940,000 units. While this may sound like a lot, it is quite low compared to the tens of millions produced in other years.
During the late 1920s, very few people thought to save brand-new half dollars as collectibles. Fifty cents was a significant amount of money at the time—equivalent to about $8.00 today—so most 1928-S halves went straight into circulation. They were used to buy groceries, movie tickets, and gasoline, leading to the heavy wear we see on most surviving examples.

Finding a “Gem” quality 1928-S (graded MS-65 or higher) is a “Holy Grail” moment for many collectors. These coins survived the decades with their original mint luster intact, appearing as bright and shiny as the day they were struck. Because they are so rare, they often appear only at major auctions, where wealthy collectors bid thousands of dollars to fill a hole in their sets.
Common Varieties and Errors to Look For
While there aren’t many famous “major” errors for the 1928-S, collectors do look for specific strike characteristics. As mentioned, the 1928-S is notorious for a “soft strike.” This means the dies weren’t pressed hard enough into the silver planchet, resulting in fuzzy details even on a coin that was never used.
If you find a 1928-S that has incredibly sharp, crisp details (a “Full Strike”), it will command a significant premium over a standard strike in the same grade. Collectors also look for “laminations”—cracks or peels in the metal surface that occurred during the minting process. While these are technically errors, they don’t always add value unless they are very dramatic.
Checking your coin under a 10x magnifying loupe is the best way to spot these tiny details. You can also use CoinKnow to zoom in on high-resolution reference photos to see exactly where the “S” mint mark should be and what a “Full Strike” eagle looks like compared to your coin.

How to Store and Sell Your 1928 Silver Half Dollar
If you believe you have a valuable 1928-S, how you handle it is critical. Never, ever clean your coin. Cleaning a vintage silver coin with polish, baking soda, or even a soft cloth can leave microscopic scratches that destroy its collector value. A cleaned “Uncirculated” coin might lose 50% or more of its market price instantly.
Store your coin in a PVC-free plastic flip or a cardboard “2×2” holder. This prevents the silver from reacting with the air and developing “toning” or tarnish, although some collectors actually pay more for naturally “rainbow-toned” coins. Keeping the coin in a dry, cool place is essential for long-term preservation.
| Selling Method | Pros | Cons |
|---|---|---|
| Local Coin Shop | Fast cash; no shipping risks. | Lower payout (wholesale price). |
| Online Auctions (eBay) | Direct to collectors; higher price. | Fees; shipping; risk of returns. |
| Major Auction Houses | Best for high-grade (MS) coins. | Long wait times; high commissions. |
Before selling, use CoinKnow to track recent realized auction prices. This gives you leverage when negotiating with a dealer. Remember that a dealer needs to make a profit, so they will typically offer you 60% to 80% of the coin’s retail value.
FAQ
Q: Is every 1928 half dollar an “S” mint?
A: Yes. In 1928, the San Francisco Mint was the only U.S. mint facility to produce Half Dollars. If your coin says 1928, it should have an “S” on the back. If it doesn’t, it might be heavily worn or altered.

Q: How much silver is in a 1928-S Walking Liberty Half Dollar?
A: It contains 0.36169 troy ounces of pure silver. You can calculate its “melt value” by multiplying the current spot price of silver by 0.36.
Q: Should I get my 1928-S coin professionally graded?
A: Only if it is in exceptionally good condition (AU or Mint State). Since grading costs $30-$50 plus shipping, it isn’t worth it for a coin that is only worth $20. If your coin looks “brand new,” grading is a must.
Q: Why is the “S” mint mark so important?
A: In many other years, Philadelphia (no mint mark) or Denver (D) produced more coins. The “S” mark from San Francisco often indicates a lower mintage, which usually leads to higher collector demand and higher prices.
