The 1945-S Mercury Dime is worth anywhere from $2.50 in worn condition to over $1,200 in pristine mint state with “Full Bands” details. If you have recently found one of these beautiful silver coins in an old jar or a family collection, you are holding a piece of American history minted during the final year of World War II.

| Fine (F-12) to Very Fine (VF-20) | $4.00 – $6.50 |

Identifying Your 1945-S Mercury Dime
Understanding the 1945-S Mercury Dime value begins with identifying the coin’s specific characteristics. This coin, officially known as the “Winged Liberty Head Dime,” features the profile of Liberty wearing a Phrygian cap with wings, which symbolized freedom of thought.
If you are unsure whether you have a San Francisco mint mark or another variety, using a top coin identifier app can help you zoom in on the tiny “S” located on the reverse side. The “S” signifies it was produced at the San Francisco Mint, which had a relatively high mintage this year of over 58 million coins.
While that sounds like a lot, many were lost to circulation or melted down for their silver content over the decades. Today, casual collectors often use the CoinKnow app to quickly verify their finds and get instant estimates on whether their coin is a common specimen or a rare variety.

The Importance of Silver Content in 1945 Dimes
Even if your 1945-S Mercury Dime is heavily worn, it still holds significant value because of its metal composition. Unlike modern dimes, which are made of copper and nickel, the 1945-S dime is composed of 90% silver and 10% copper.
This means the coin has a “melt value” that fluctuates with the current market price of silver. Even in the worst possible condition, a Mercury Dime is rarely worth less than its weight in silver. For many hobbyists, checking the 1945 dime value based on silver spot prices is the first step in valuation.

When silver prices rise, the baseline value of these coins increases across the board. However, the 1945-S is often sought after by collectors who want to complete a “San Francisco” set, which can push the price slightly above the basic silver value even for circulated examples.
Understanding the San Francisco “S” Mint Mark Varieties
In 1945, the San Francisco mint produced two distinct versions of the mint mark: the “Large S” and the “Micro S.” The Micro S variety is particularly famous among collectors because the mint mark is noticeably smaller than usual.

The Micro S was created when the mint mistakenly used a punch intended for a different coin or an older style. This variety carries a premium in higher grades. If you have a magnifying glass, look at the bottom left of the torch on the reverse; if the “S” looks tiny and somewhat cramped, you might have a Micro S.
| Variety | MS-60 Price | MS-65 Price |
|---|---|---|
| 1945-S Standard | $15 | $45 |
| 1945-S Micro S | $25 | $90 |
The “Full Bands” Factor: What Makes a Dime Worth Thousands?
For professional collectors, the ultimate prize is a 1945-S Mercury Dime with “Full Bands” (FB). This refers to the horizontal straps that hold the bundle of rods (fasces) together on the back of the coin.
Because the dies used in 1945 were often worn down, it was very rare for the strike to be strong enough to show a clear, distinct line between these bands. A coin with Full Bands is proof of a superior strike. Looking at the 1945-S Mercury Dime price by grade, you will notice a massive price jump between a standard Mint State coin and one designated as FB.

For instance, a standard MS-67 1945-S might sell for $100, while the same coin with “Full Bands” can fetch several thousand dollars at auction. If you think your coin has this level of detail, using CoinKnow to compare it with high-resolution images is a great way to double-check before spending money on professional grading.
Grading Your Coin: From Good to Uncirculated
Condition is everything in the world of coin collecting. Most 1945-S Mercury Dimes found today are in “Circulated” condition, meaning they were used in daily commerce. These will show wear on Liberty’s hair and the feathers of her cap.
If the coin looks shiny and has no visible scratches or wear on the high points, it might be “Uncirculated.” Uncirculated coins are graded on a scale from 60 to 70. A 1945-S Mercury Dime in MS-65 or higher is considered a “Gem” and is highly desirable.
To get an accurate idea of your coin’s grade, look for the following:
– Good: Liberty’s head is a silhouette; the legend is visible but faint.
– Fine: Some hair detail is visible; the rim is full.
– Extremely Fine: All hair lines are visible; only slight wear on the highest points.
– Mint State: No wear at all; original luster is present.

How to Store and Protect Your Mercury Dime
If you discover that your 1945-S Mercury Dime is in high grade or is a Micro S variety, you must protect it immediately. Silver is a soft metal and tarnishes (oxidizes) when exposed to air and moisture.
Never clean your coins! Cleaning a coin with chemicals or even a soft cloth can leave microscopic scratches that permanently destroy its collector value. Most experienced collectors recommend using PVC-free coin flips or “slabs” to keep the coin in a stable environment.
By keeping your coin safe, you preserve its historical integrity and its market value. Many users of the CoinKnow app also use the digital portfolio feature to track the value of their protected collection over time, ensuring they know exactly what their investment is worth.
| Condition | 1945-S Value | 1945-P Value | 1945-D Value |
|---|---|---|---|
| Average Circulated | $2.50 | $2.50 | $2.50 |
| Mint State 63 | $22 | $20 | $22 |
| Mint State 65 Full Bands | $350 | $15,000+ | $100 |
FAQ
Q: Where is the mint mark on a 1945 Mercury Dime?
A: The mint mark is found on the reverse (back) of the coin. Look at the bottom left, near the base of the torch and the letter “E” in “ONE.” If you see an “S,” it was minted in San Francisco. If you see a “D,” it’s from Denver. No letter means it was minted in Philadelphia.

Q: Is a 1945-S Mercury Dime real silver?
A: Yes, all Mercury Dimes minted in 1945 are 90% silver. They contain approximately 0.07234 troy ounces of pure silver, which gives them a base value regardless of their condition as a collectible.
Q: How much is a 1945-S Micro S worth?
A: A 1945-S Micro S dime is worth about $5 to $10 in average circulated condition, but in high-grade uncirculated condition (MS-65), it can be worth $90 to $150 or more.
Q: Why is the 1945 Philadelphia (No Mint Mark) Full Bands so expensive?
A: While the 1945-S is rare in Full Bands, the 1945 Philadelphia version is the “King” of Mercury Dimes in Full Bands. Because of notoriously poor striking at the Philly mint that year, finding one with clear bands is almost impossible, leading to prices over $15,000 for top grades.
