1928 S Mercury Dime Value and Pricing Guide for Collectors
The 1928-S Mercury Dime is worth anywhere from $3 in worn condition to over $1,200 in pristine mint state. If you have found one of these beautiful silver coins in an old jar or a family collection, you are holding a piece of American history that carries significant premium over its face value.
Why the 1928 S Mercury Dime is Highly Collectible
The 1928-S Mercury Dime stands out because it was minted in San Francisco during a transitional period in American history. Unlike the millions of dimes struck in Philadelphia, the San Francisco “S” mint mark usually indicates a lower mintage, which often leads to higher demand among hobbyists. These coins are composed of 90% silver and 10% copper, meaning they have intrinsic bullion value even if the surface is heavily worn. However, collectors don’t just look at the silver content; they look at the history and the strike quality. If you are unsure if your coin is genuine, you can use a free coin identifier app to quickly check the details of your find.
Using tools like CoinKnow helps everyday people distinguish between a common circulated coin and a rare treasure. In 1928, the San Francisco mint produced roughly 6.7 million of these dimes. While that sounds like a lot, many were lost to circulation or melted down during times when silver prices spiked. This makes finding one in high grade quite a challenge for modern hunters.
Understanding the Condition and 1928 Dime Value
When determining how much your coin is worth, “grading” is the most critical factor. A coin that has been rattled around in pockets for decades will be “Good” or “Fine,” showing a flat profile of Lady Liberty. A coin that looks like it just came from the bank is “Uncirculated” or “Mint State.” The difference in price is staggering. For example, the 1928-S Mercury Dime value in Mint State can reach hundreds of dollars, whereas a worn version might only buy you a cup of coffee.
To get an accurate estimate, look at the feathers in Lady Liberty’s cap and the diagonal lines on the “fasces” (the bundle of sticks) on the back. If these lines are sharp and distinct, you have a high-value item. CoinKnow can assist you in comparing your coin to high-resolution images of various grades. Many beginners find that their coins are in the “Fine” to “Very Fine” range, which still commands a nice premium over the silver melt value.

Identifying Mint Marks and Key Features
To ensure you have the San Francisco minting, you must locate the “S” mint mark. On the Mercury Dime, this is found on the reverse (tails) side, near the bottom left, just to the left of the base of the fasces. If there is no letter there, the coin was minted in Philadelphia. If there is a small “D,” it was minted in Denver. Each mint has a different rarity level and price point.
General information regarding the 1928 silver dime worth and rarity shows that the “S” mint is often the most desirable of the three for that specific year in higher grades. When examining your coin, avoid cleaning it with chemicals or cloths, as this can drastically reduce its numismatic value. Collectors prefer “original skin,” which is the natural patina or toning the coin has developed over the last 90+ years. Using an app like CoinKnow helps you document your collection without risking damage to the physical coins.
The “Full Bands” Rarity Factor
Serious collectors often look for a specific designation called “Full Bands” (FB). This refers to the horizontal bands holding the bundle of sticks (fasces) on the reverse of the coin. Because these are the highest points of the design, they are often the first to wear down or may not have been fully struck by the minting machine.
A 1928-S Mercury Dime with Full Bands is incredibly rare and can command a massive price at auction, sometimes reaching several thousands of dollars. If the middle bands are clearly separated with no merging, you have found a numismatic gem. Most coins found in circulation will not have this feature, but it is always worth checking with a magnifying glass.
Q: How can I tell if my 1928-S dime is real silver?
A: All Mercury Dimes minted from 1916 to 1945 are 90% silver. You can tell by the sound (it has a high-pitched ring when gently tapped) and the appearance of the edge, which won’t show the copper stripe found on modern dimes.
Q: Where is the mint mark on a 1928 Mercury Dime?
A: The mint mark is located on the reverse side of the coin, at the bottom near the rim, to the left of the bundle of sticks (fasces). Look for a small “S” for San Francisco or “D” for Denver.
Q: Should I clean my 1928-S Mercury Dime to make it worth more?
A: No! Never clean a rare coin. Cleaning creates microscopic scratches that professional graders can detect instantly, and it can reduce the value of your silver dime by 50% or more.
