1991-S Roosevelt Dime Value: Most Recent Collector Prices

The 1991-S Roosevelt Dime is worth anywhere from $3 in standard proof condition to over $1,000 for rare “Deep Cameo” specimens in perfect grade. While you won’t find this specific “S” mint mark coin in your pocket change, it remains a favorite for collectors looking to complete their modern sets.

Understanding the 1991-S Roosevelt Dime History

If you have stumbled upon a 1991 dime with a small “S” next to the date, you are looking at a Proof coin. Unlike the dimes minted in Philadelphia or Denver for daily commerce, these coins were produced at the San Francisco Mint specifically for collectors. They were originally sold in plastic-encased sets directly from the United States Mint, meaning they were never intended to be spent at a grocery store or vending machine.

If you are unsure whether your coin is a standard circulation strike or a proof, using a free coin identifier app can help you distinguish the mirrored surface of the 1991-S from its matte-finish counterparts. In 1991, the Mint produced over 2.8 million proof sets. This high production number means that the 1991-S is common in the collector market, but finding one in truly pristine, flawless condition is where the real value lies.

Collectors admire the Roosevelt Dime series for its longevity and its tribute to President Franklin D. Roosevelt, who founded the March of Dimes. When you examine your 1991-S, you are seeing a coin from an era where minting technology was becoming incredibly precise, leading to the high-quality “Deep Cameo” finishes that investors look for today. By using an app like CoinKnow, you can quickly track the market trends for these modern proof coins.

Identifying Features of the 1991-S Proof Dime

The 1991-S Roosevelt Dime is composed of a copper core with a cladding of copper-nickel (75% copper, 25% nickel). It weighs 2.27 grams and has a diameter of 17.9 millimeters. The most striking feature of the 1991-S is the “Proof” finish. These coins were struck at least twice with polished dies on specially prepared planchets. This results in a reflective, mirror-like background (the fields) and a frosted, matte finish on the design (the devices).

The “S” mint mark is located just above the date on the right side of the coin’s obverse. At a glance, the coin should look much shinier and more detailed than a standard dime. If your coin looks dull or scratched, it might have been “impaired,” meaning it was removed from its protective set and spent as regular money. Impaired proofs are generally only worth their face value of ten cents, or perhaps a small premium to a curious beginner.

To ensure you aren’t overlooking a rarity, it is helpful to compare your specimen to the current market rates for 1991 Roosevelt dimes. While the “S” version is a proof, understanding how it stacks up against the Philadelphia (P) and Denver (D) coins from the same year provides a complete picture of the 1991 series. Many users find that CoinKnow helps them organize their collection and identify these distinct minting differences.

Grading and 1991-S Dime Value Factors

The value of a 1991-S Roosevelt Dime is almost entirely dependent on its numerical grade, specifically from PR 65 to PR 70. Professional grading services like PCGS or NGC use this scale to determine how close a coin is to perfection. For modern proofs, anything below a PR 69 is considered relatively common. However, a PR 70 Deep Cameo (DCAM) is the “holy grail” for this year, as it represents a coin with no visible flaws even under 5x magnification.

The “Deep Cameo” designation is critical. This refers to the extreme contrast between the shiny background and the milky-white frost on Roosevelt’s face and the torch on the reverse. If the frost is light or patchy, the coin is simply labeled “Cameo” or just “Proof,” which significantly lowers the resale value. Most 1991-S dimes found in their original government purple-colored boxes are likely in the PR 67 to PR 69 range.

If you are trying to estimate the price of your collection, looking up the 1991 dime value for different mint marks is a smart move. While the Philadelphia and Denver coins are valued in “Mint State” (MS), the San Francisco coins use the “Proof” (PR) prefix. Using an app like CoinKnow allows you to scan the coin and get an instant estimation based on these specific grading nuances, saving you the cost of professional grading if the coin isn’t a top-tier specimen.

Knowing the exact price jumps between grades can help you decide if it is worth paying $20 or more to have your coin professionally certified. Generally, it only makes financial sense to grade a 1991-S if you are confident it will hit the PR 70 mark.

Common 1991-S Roosevelt Dime Errors to Watch For

While errors are much rarer in proof coins compared to circulation coins, they do exist and can command high prices. Collectors of the 1991-S should look for “Double Dies.” A doubled die occurs when the hub strikes the die multiple times at slightly different angles. On a 1991-S dime, you would most likely see this as a slight thickening or blurring of the letters in “IN GOD WE TRUST” or “LIBERTY.”

Another potential error is the “Struck Through.” This happens when a piece of debris, such as grease or a tiny fragment of thread, gets caught between the die and the planchet. This leaves an indentation or a “soft” spot on the coin’s surface where the detail didn’t fully form. Because quality control at the San Francisco Mint is extremely strict, such errors in 1991-S proofs are highly sought after by specialists.

Finally, keep an eye out for “Off-Center” strikes. Although very rare for proof sets, if the coin was not perfectly aligned in the press, part of the design might be missing. If you think you’ve found an error, use CoinKnow to browse community galleries of confirmed errors. Comparing high-resolution photos of known errors with your coin is the best way to verify if you have a unique treasure or just a standard proof.

Why the 1991-S Proof Dime is a Great Collectible

The 1991-S is an excellent entry point for new collectors because it is affordable yet beautiful. Most people can acquire a high-grade PR 69 example for the price of a lunch, allowing them to own a piece of minting history that looks far more impressive than the dimes found in their change. It serves as a great “bridge” coin—something that teaches you about mint marks, proof finishes, and the importance of coin preservation.

For those looking to build a “Registry Set” (a complete collection of the highest possible grades), the 1991-S in PR 70 is a mandatory and challenging acquisition. Because these sets were often handled by hobbyists over the last 30 years, many coins have developed “haze” or small spots from humidity, making the pristine, crystal-clear survivors quite rare. Keeping your dime in its original mint packaging or a PVC-free plastic holder is essential to maintaining its value.

In summary, whether you found a 1991-S in an old desk drawer or inherited a proof set from a relative, it is a coin worth examining. While most are worth a few dollars, the potential for a high-grade rarity or a subtle mint error makes it an exciting part of the Roosevelt Dime series.

FAQ

Q: Can I find a 1991-S dime in my pocket change?

A: It is very unlikely but possible. 1991-S dimes are Proof coins that were sold in sets. If someone broke open a set and spent the coins, the dime could end up in circulation. However, it would likely be scratched and lose its “Proof” value.

Q: Is the 1991-S dime made of silver?

A: No. The 1991-S Roosevelt Dime is a standard clad coin made of copper and nickel. The San Francisco Mint did not start producing silver proof dimes again until 1992.

Q: How can I tell if my 1991-S dime is a “Deep Cameo”?

A: A Deep Cameo (DCAM) coin will have a very strong contrast. The portrait of Roosevelt will look white and frosted, like it was painted on, while the background will look like a dark, polished mirror. If the contrast is weak, it is just a standard proof.

Q: What is the most ever paid for a 1991-S dime?

A: In recent years, perfect PCGS PR 70 Deep Cameo specimens have sold for over $1,000 at major auctions. Most 1991-S dimes, however, sell for between $3 and $20.
