What Makes the 1979-S Type 1 Roosevelt Dime Special?
The 1979-S Roosevelt Dime is a Proof coin, which means it was specially struck by the San Francisco Mint for collectors using polished dies and planchets. If you are trying to identify a mystery coin in your possession, using a top coin identifier and value app is the fastest way to confirm if you have a Proof or a regular business strike. Unlike the dimes you spend at the grocery store, these coins have a mirror-like finish and sharp details.
In 1979, the Mint updated the design of the “S” mint mark mid-year, leading to two distinct versions known as Type 1 and Type 2. The Type 1 variety features what collectors call a “Filled S.” This occurs because the minting dye used to create the mint mark was worn down, resulting in an “S” that looks like a blob or is partially filled with metal.
Scanning your collection with CoinKnow can help you distinguish between the common and the rare. While the Type 2 (Clear S) is generally more desirable, the Type 1 is a cornerstone of any Roosevelt Dime set. Its value is heavily dependent on its “Cameo” effect—the contrast between the frosty portrait of FDR and the shiny background.

Identifying the Type 1 Filled S Mint Mark
To determine the 1979-S Type 1 dime value, you must first look closely at the mint mark located just above the date. On a Type 1 coin, the loops of the “S” are not clearly defined. It often looks like a rectangular or oval-shaped lump of copper-nickel. In contrast, the Type 2 has a very clear, bulbous “S” with distinct openings in the loops.

Because Proof coins are handled carefully, most survive in excellent condition. However, even small scratches or “hairlines” can drastically reduce the price. Professional grading is often necessary for coins that appear perfect to the naked eye. To see how these grades affect the price, you can view the 1979 Roosevelt Dime price data by grade.
The Type 1 is significantly more common than the Type 2 for this year. The Mint transitioned to the new punch late in the production cycle, meaning millions of Type 1 dimes were produced compared to a smaller number of Type 2s. Despite this, a Type 1 in a perfect PR 70 deep cameo grade still commands a premium among registry set collectors.

Value Breakdown: How Much is My 1979-S Dime Worth?
For most casual finders, a 1979-S Type 1 dime will be worth its “melt” value or a small premium of a few dollars. These coins were sold in brown-colored Proof Sets originally. If the coin has been removed from its original plastic packaging and handled, it may lose its Proof luster, becoming what collectors call an “impaired proof.”
If you find one in a collection, check for a “Deep Cameo” (DCAM) designation. This means the frosted parts of the design are thick and white, while the fields are like black mirrors. These are the pieces that sell for high amounts at auction. CoinKnow can assist you in comparing your coin’s luster to high-grade examples online.
| Condition Designation | Average Price | Availability |
|---|---|---|
| Proof (No Cameo) | $2.00 | Very Common |
| Cameo (Moderate Contrast) | $5.00 | Common |
| Deep Cameo (Extreme Contrast) | $15 – $400+ | Scarce in PR70 |
Comparison: 1979-S Type 1 vs. Type 2
Understanding the difference between the two types is the key to unlocking the potential value of your coin. While the Type 1 is the focus here, knowing what it is not helps confirm its identity. The Type 2 “Clear S” was a new design meant to improve the aesthetic of the mint mark, featuring clear serifs and a distinct center.

The market generally pays a 2x to 5x premium for the Type 2 over the Type 1 in lower grades. However, because many Type 1 coins were used to fill sets, high-quality Type 1s are still very much in demand. You can find more comprehensive 1979 dime value information to compare standard 1979-P and 1979-D dimes with your Proof “S” versions.
Many people mistakenly think a 1979 dime is made of silver. It is important to remember that the US Mint stopped making silver circulating dimes in 1964. The 1979-S is a copper-nickel clad coin. Its value comes entirely from its collector appeal and strike quality, rather than its metal content.
Factors that Influence the Price of 1979-S Proof Dimes
Three main factors determine the final price of a 1979-S Type 1 dime: eye appeal, surface preservation, and the presence of errors. Even though these were minted in a controlled environment, errors can still occur. Look for “doubled dies,” where the lettering appears to have a shadow or second layer.

Surface preservation is critical. Because Proof coins have mirror-like surfaces, even the tiniest fingerprint can cause permanent damage through “milky spots” or oxidation. If you have a coin that looks flawless, do not touch the surface with your fingers; hold it only by the edges. Using CoinKnow to photograph and archive your finds is a great way to track your collection’s condition over time.
| Factor | Impact on Value |
|---|---|
| Fingerprints/Tarnish | Reduces value by 50-70% |
| Full Bands (Reverse) | Standard on Proofs (Neutral) |
| Original US Mint Packaging | Adds $2-3 to the total set |
How to Sell Your 1979-S Roosevelt Dime
If you discover that you have a high-grade 1979-S Type 1, your next step is deciding whether to sell or keep it. For coins worth less than $10, selling them individually on eBay might not be worth the shipping costs. These are best sold in bulk or as part of a complete 1979 Proof set.
However, if your coin earns a PR 70 grade from a service like PCGS or NGC, it could be worth hundreds. In these cases, reaching out to a specialized auction house or a reputable local coin dealer is the best route. Before you go, make sure you have done your research so you know exactly what variety you are holding.
