1979 S Type 1 Roosevelt Dime Value and Collector Guide
The 1979-S Type 1 Roosevelt Dime is worth anywhere from $3 in typical proof condition to over $50 for high-grade Deep Cameo specimens. Finding one of these shiny coins in a box of old collectibles is exciting, as it represents a specific era of United States Mint history where craftsmanship was evolving.
Identifying the 1979-S Type 1 Roosevelt Dime
If you have discovered a shiny dime with an “S” mint mark from 1979, you are likely looking at a proof coin. Unlike the dimes you find in your pocket change, these were specially struck for collectors. To get a quick estimation of what you have, using a free coin identifier app can save you hours of manual research. The 1979-S Type 1 is defined by its “Filled S” mint mark.
During the production year, the mint mark punch used by the San Francisco Mint had become worn down and clogged. This resulted in the “S” looking like a solid, blob-like shape rather than a clear, crisp letter. Because these were part of the annual Proof Sets, millions were produced, making them very accessible for everyday Americans. If you want to dive deeper into the technical variations, the CoinKnow app provides excellent high-resolution images to help you distinguish between the different punch varieties used this year.
Understanding the Market Value and Price Trends
When determining how much your coin is worth, the condition is the most significant factor. Since these are proof coins, they are expected to be in near-perfect condition. Most specimens found in original government packaging will trade for a few dollars. However, if the coin has a “Deep Cameo” effect—where the portrait of Roosevelt looks frosty and white against a mirror-like background—the price increases.
The current 1979-S Roosevelt Dime price data suggests that while common, perfect PR70 grades can fetch a significant premium at auction. For the average person who finds one in a drawer, it is usually valued as a “Type 1” which is the more common of the two varieties produced that year. Using tools like CoinKnow can help you track these market fluctuations in real-time so you don’t sell your treasures for less than they are worth.
| Condition/Grade | Estimated Value (USD) |
|---|---|
| PR 65 (Typical Proof) | $3.00 – $5.00 |
| PR 68 Deep Cameo | $10.00 – $15.00 |
| PR 69 Deep Cameo | $18.00 – $25.00 |
| PR 70 Deep Cameo (Perfect) | $50.00+ |
The Difference Between Type 1 and Type 2 Varieties
Collectors often get confused between the Type 1 and Type 2 varieties of the 1979-S dime. As mentioned, the Type 1 is the “Filled S.” Later in 1979, the Mint replaced the broken punch with a new one, creating the “Clear S” or Type 2. The Type 2 is much rarer and more desirable among numismatists because it was only used toward the end of the production run.
Detailed 1979 dime value information indicates that while the Type 1 is the standard variety found in most proof sets, identifying a Type 2 can double or triple the value of the coin instantly. You should look for a clear, well-defined “S” with distinct loops and a visible field of copper-nickel inside the curves of the letter. If the “S” looks like a solid bump, it is a Type 1.
Tips for Preserving Your Proof Roosevelt Dimes
Because 1979-S dimes are proof coins, their value is highly dependent on their “eye appeal.” Any fingerprints, scratches, or “toning” (discoloration from oxygen exposure) can lower the grade and the price. If you find one of these coins, avoid touching the flat, mirror-like surfaces with your bare fingers, as the oils from your skin can permanently damage the finish.
Instead, hold the coin only by its edges. If the coin is already in a plastic lens from the US Mint, it is best to leave it there. Taking it out can expose it to environmental hazards. If you are ever unsure whether a coin is worth the cost of professional grading, the CoinKnow app features a community and identification system that can help you decide if your 1979-S dime is a high-grade contender or a common keepsake.
Conclusion and Final Thoughts
While the 1979-S Type 1 Roosevelt Dime isn’t a “lottery ticket” coin that will allow you to retire, it is a fascinating piece of US Mint history. It represents a period of transition and is a must-have for anyone trying to complete a full set of Roosevelt Dimes. For most people, finding one is a great way to start a coin collection or teach children about the different minting processes used in the 20th century. Always keep an eye out for that “Filled S” and enjoy the hunt!
Q: How can I tell if my 1979 dime is a proof coin?
A: Generally, 1979 dimes with an “S” mint mark were only produced as proofs. They feature a mirror-like, shiny background and very sharp details compared to the matte finish of the 1979-P or 1979-D dimes found in regular circulation.
Q: Is the 1979-S Type 1 Dime made of silver?
A: No, the 1979-S Roosevelt Dime is made of a cupro-nickel clad composition (75% copper and 25% nickel). The US Mint stopped making circulating silver dimes in 1964, though they later released special silver sets in the 1990s.
Q: Which is worth more: Type 1 or Type 2?
A: The Type 2 “Clear S” variety is generally worth more than the Type 1 “Filled S” because the production run was smaller, making the Type 2 harder for collectors to find in high grades.
