The 1999-S Roosevelt Dime is worth anywhere from $5 in standard proof condition to over $500 for perfect specimens with deep cameo contrasts. If you have found a shiny dime with an “S” mint mark from 1999, you are holding a coin specifically minted for collectors rather than daily spending.
The Unique History and Appeal of the 1999 S Silver Dime
The year 1999 was a significant one for the United States Mint, marking the start of the 50 State Quarters Program. However, for Roosevelt Dime enthusiasts, the 1999-S stands out because it represents a return to tradition in the San Francisco Mint’s production line. Unlike the copper-nickel clad dimes you find in your pocket change, 1999-S proof dimes were struck in two distinct compositions: the standard clad version and a highly coveted 90% silver version.
To determine which one you have, you can use a top coin identifier app to analyze the luster and edges of your coin. If the edge of the dime shows a solid white silver stripe rather than a copper-colored core, you likely have the silver variant. These coins were never intended for circulation, meaning that if you found one in a coin jar, it likely escaped from a collector’s “Proof Set.”
The CoinHix app can help you distinguish between these two types if you are unsure about the metallic composition. Collectors often seek out these “S” mint mark coins because of their superior mirror-like finishes and sharp details, which are achieved through multiple strikes by the coin press.
Understanding the Difference Between Clad and Silver Proof Dimes
Price is largely dictated by the metal content and the grade. In 1999, the San Francisco Mint produced over 3.3 million clad proof dimes and roughly 800,000 silver proof dimes. Because the silver version was produced in much lower quantities and contains actual precious metal, its baseline value is naturally higher.
The 1999 Roosevelt Dime auction records show that silver proofs often trade for a premium, especially when they feature “Deep Cameo” (DCAM) effects. This effect creates a stark contrast between the frosted portrait of FDR and the mirror-like background fields of the coin.
When you are assessing your coin, look for any scratches or “milk spots.” Even a tiny fingerprint can lower the value significantly because collectors of proof coins demand perfection. Using the CoinHix tool can help you zoom in on these imperfections before you decide to send a coin to a professional grading service like PCGS or NGC.
Evaluating the 1999 S Roosevelt Dime Value
The market for modern proof dimes is stable, but high-grade examples can still fetch surprising prices. For most people, a 1999-S clad dime is worth about $3 to $7. However, if the coin is a 90% silver proof, the value starts at around $10 and increases based on the current spot price of silver.
You should consult a current 1999 dime price guide to see how market fluctuations affect these collectibles. In the highest possible grade—PF 70 Deep Cameo—these dimes can sell for $50 to $100. Rare errors, though extremely uncommon on proof coins, could push the price even higher.
| Coin Version | Condition / Grade | Estimated Value |
|---|---|---|
| 1999-S Clad Proof | PR 65 to PR 69 DCAM | $3.00 – $12.00 |
| 1999-S Clad Proof | PR 70 DCAM (Perfect) | $35.00+ |
| 1999-S Silver Proof | PR 65 to PR 68 DCAM | $10.00 – $18.00 |
| 1999-S Silver Proof | PR 70 DCAM (Perfect) | $60.00 – $500.00+ |
How to Tell If Your 1999 Dime Is Rare
Most 1999 dimes you find in your change will have a “P” or “D” mint mark, representing Philadelphia or Denver. These are common and generally only worth their face value of ten cents unless they are in exceptional “Mint State” condition. The “S” mint mark is the key indicator that you have something special.
If you find a 1999-S dime while searching through rolls of coins, it usually means someone broke open a proof set to spend the money. These are called “impaired proofs.” While they are rarer than “P” or “D” dimes, their value drops if they have been scratched or worn down by other coins in circulation.
To maximize the potential of your find, keep the coin in a protective flip or a soft cloth. Do not attempt to clean it, as cleaning a proof coin with a cloth will create “hairlines,” which are tiny scratches that destroy the collector’s value. Pro collectors often use CoinHix to catalog their finds and track value trends over time.
Frequently Asked Questions About 1999 S Roosevelt Dimes
Q: How can I tell if my 1999-S dime is silver or clad?
A: The easiest way is the “Weight Test” or the “Edge Test.” A silver dime will have a bright white edge with no copper stripe and weighs 2.50 grams. A clad dime has a visible copper ring on the edge and weighs 2.27 grams.
Q: Is a 1999 dime with no mint mark rare?
A: No. A 1999 dime with no mint mark was made in Philadelphia (though usually, they have a ‘P’ mark). In the case of dimes from the late 90s, millions were produced, and they are generally worth just ten cents.
Q: Can I spend a 1999-S dime at a store?
A: Yes, it is legal tender and worth 10 cents at any shop. However, because its collector value is at least $3 to $10, you would be losing money by spending it.
Q: Where is the mint mark located on a 1999 Roosevelt Dime?
A: The mint mark is located on the obverse (front) of the coin, just above the date on the right side of Roosevelt’s neck. Look for the small “S” to confirm it is a proof coin.
