The Significance of the 1930-S Mercury Dime
If you have stumbled upon an old silver dime featuring a winged lady, you are holding a piece of American art. Officially called the “Winged Liberty Head,” it is commonly known as the Mercury Dime. The 1930-S edition is particularly interesting because it represents the final year of production before the Great Depression caused the Mint to pause dime production from 1931 to 1933. Finding one in your change is rare, and identifying its exact grade is the first step toward knowing its true market price. For beginners, using a top coin identifier and value app can make the identification process much easier.
With a mintage of 1,840,000, the 1930-S is considered a semi-key date in the series. While it is not as elusive as the legendary 1916-D, it is significantly harder to find than the 1930 Philadelphia issue. Many of these coins were heavily circulated, meaning they spent years in people’s pockets, buying bread and newspapers during the 1930s. Today, finding a high-grade 1930-S Mercury Dime is a challenge for collectors, which is why prices jump significantly for coins that still look “shiny” or brand new.
If you are unsure whether your coin is a genuine 1930-S or just a common 1930, you can use the CoinKnow app to scan and verify the mint mark instantly. This tool helps everyday people avoid getting ripped off when selling their finds to local coin shops or online buyers.

How to Identify the ‘S’ Mint Mark
The “S” on your 1930 dime stands for the San Francisco Mint. To find it, you need to flip the coin over to the reverse (back) side. Look at the bottom of the coin, just to the left of the base of the fasces (the bundle of rods with an axe). If you see a small “S” there, you have a 1930-S Mercury Dime. If that area is blank, your coin was minted in Philadelphia. Philadelphia dimes from this year are generally worth less because over 13 million of them were made.

Understanding the rarity of the San Francisco minting is crucial. Because far fewer coins were struck in California that year, the 1930 dime market trends show a consistent premium for the “S” mark across all grades. Even a heavily worn S-mint dime can be worth three to four times its silver melt value.
If the mint mark is hard to see due to dirt or wear, don’t try to scrub it off! Cleaning a coin with chemicals or abrasive cloth can destroy its numismatic value. Instead, use a magnifying glass or a digital identification tool like CoinKnow to get a clearer look at the surface details without damaging the metal.

Understanding the Grade and Condition
The value of your 1930-S Mercury Dime is dictated almost entirely by its condition, or “grade.” Professional graders use a 70-point scale, where 1 is barely recognizable and 70 is perfect. For most people finding coins in old jars, the coin will likely fall into the “Good” to “Very Fine” range. At these levels, the coin shows significant wear on Liberty’s hair and the feathers on her cap.
In “About Uncirculated” or “Mint State” conditions, the 1930-S becomes a high-ticket item. You are looking for original mint luster—that satiny sheen that reflects light. Collectors often look for the 1930-S Mercury Dime MS price range to determine if their coin is worth sending to a professional grading service like PCGS or NGC. A coin in MS-65 condition can be worth over $400, while one with “Full Bands” can reach even higher heights.
| Grade Group | Visual Description | Avg. Price |
|---|---|---|
| Circulated (G-VF) | Heavy wear, feathers flat, date readable. | $3 – $12 |
| High Grade (XF-AU) | Slight wear on high points, some luster remains. | $18 – $55 |
| Uncirculated (MS) | No wear, full luster, sharp details. | $95 – $1,200+ |
What Are ‘Full Bands’ and Why Do They Matter?
When researching the 1930-S Mercury Dime value, you will often see the abbreviation “FB” or “FBL.” This stands for “Full Bands.” On the reverse of the dime, the fasces is held together by horizontal leather bands. In the center of the bundle, there are two sets of bands. If these bands are fully separated with a clear line between them, the coin is designated “Full Bands.”

This is a strike characteristic, not just a matter of wear. Many dimes were struck with worn dies, meaning the bands were never fully distinct even when the coin was brand new. Therefore, a 1930-S with Full Bands is incredibly rare and highly sought after by serious collectors. A standard MS-66 1930-S might sell for $500, but the same coin with the “FB” designation could easily fetch $1,500 or more at auction.
To check for this feature, you need deep magnification. Using the high-resolution camera on your smartphone with the CoinKnow app can help you zoom in on these tiny details. If those central bands are crisp and distinct, you’ve hit the jackpot.
Silver Content vs. Numismatic Value
Even if your 1930-S Mercury Dime is in terrible condition—scratched, bent, or heavily worn—it is still worth more than ten cents. All Mercury Dimes minted between 1916 and 1945 are made of 90% silver and 10% copper. This means they have “intrinsic” value based on the current price of silver bullion.

Each dime contains approximately 0.07234 troy ounces of pure silver. If silver is trading at $25 per ounce, the “melt value” of your dime is roughly $1.80. This provides a “floor” for the price; your coin will never be worth less than its metal content. However, because the 1930-S is a scarcer date, its numismatic (collector) value almost always exceeds its silver value, even in low grades.
| Feature | Specification |
|---|---|
| Composition | 90% Silver, 10% Copper |
| Silver Weight | 0.07234 troy oz |
| Diameter | 17.9 mm |
| Mint Facility | San Francisco (S) |
Where to Sell Your 1930-S Mercury Dime
Deciding where to sell is just as important as knowing the 1930-S Mercury Dime value. If you have a low-grade coin worth $3-$10, a local coin shop is your best bet for a quick cash sale. They will likely offer you a percentage of the retail price. If you have multiple silver coins, you can sell them as a “junk silver” lot on platforms like eBay.
For high-grade specimens or those you suspect have “Full Bands,” you should consider professional grading first. Once graded by PCGS or NGC, you can sell through major auction houses like Heritage Auctions or Stacks Bowers, where serious collectors compete for the best pieces. Before you go, always check recent sales data to ensure you are getting a fair price. Tools like CoinKnow can provide real-time auction results so you stay informed about the current market climate.

Q: How can I tell if my 1930 dime is an ‘S’ mint?
A: Look on the reverse side of the coin, near the bottom left of the fasces bundle. A small ‘S’ indicates it was made in San Francisco. A ‘D’ means Denver, and no letter means Philadelphia.
Q: What is the most expensive 1930-S Mercury Dime ever sold?
A: Top-tier specimens in MS-67 with Full Bands have sold for upwards of $10,000 at major auctions. Most everyday examples, however, sell for between $5 and $50.
Q: Should I clean my 1930-S Mercury Dime to make it look better?
