The 1998 S Roosevelt Dime is worth anywhere from $3 in typical proof condition to over $100 for a perfect museum-quality specimen. While these shiny coins are rare to find in your pocket change, they represent a high point in modern minting technology and remain affordable treasures for any collector.

The Unique Status of the 1998 S Proof Dime

If you have stumbled upon a 1998 dime that looks significantly shinier or more “mirror-like” than the ones you usually spend at the grocery store, you likely have the “S” mint mark version. Unlike the dimes minted in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for collectors. They weren’t meant to buy a soda; they were meant to be part of a prestigious Proof Set.

Because these coins were struck using polished dies and specially prepared planchets, they feature a frosted design that stands out against a deep, dark background. If you are unsure exactly what you are holding, using a top coin identifier app can help you distinguish between a well-preserved business strike and a genuine proof. For many everyday Americans, the 1998-S is the first step into the world of professional numismatics.

The CoinHix app is another excellent tool to have in your pocket when you find an unusual coin like this. It allows you to organize your finds and keep track of market fluctuations. Even though millions were made, the condition is the ultimate factor in determining if your dime is worth a few dollars or a significant premium.

Current Market Value and Price Comparison Table

When determining the value of your 1998-S dime, you must look at the “grade” or the physical condition of the coin. Most individuals who find these coins have them in “PR69” or “PR70” condition, which are the highest grades possible. Because almost all 1998-S dimes were sold in protective plastic cases, they usually arrive in excellent shape.

However, if a proof dime has been removed from its case and spent as regular money, its value drops significantly because the delicate mirror finish scratches easily. Below is a breakdown of what you can expect to receive for these coins in various states. You can also view the latest 1998 Roosevelt dime market price trends to see how values have shifted over the last few years.

Condition Grade	Estimated Market Value
PR65 (Proof – Average)	$2.50 – $4.00
PR68 (Proof – High Quality)	$5.00 – $8.00
PR69 DCAM (Deep Cameo)	$12.00 – $18.00
PR70 DCAM (Perfect Condition)	$45.00 – $110.00

What Makes the 1998 S Dime Special

The “S” mint mark is the most important feature to look for. Located just above the date on the right side of the coin, that small letter tells a big story. In 1998, the United States Mint produced over 2 billion dimes, but only about 2 million of them were S-mint proofs. This means for every 1,000 dimes made that year, only one was an S-mint proof.

Furthermore, 1998-S dimes are almost exclusively “Deep Cameo” (DCAM). This term describes the intense contrast between the frosted portrait of President Roosevelt and the mirror-like fields of the coin. If your coin looks like a black-and-white photograph where the silver elements “pop” off the background, you have a high-demand item.

Many collectors use the CoinHix platform to compare their coins against high-resolution images of Deep Cameo specimens. Understanding the 1998 S dime value factors such as luster and contact marks is the key to knowing if you should have your coin professionally graded by companies like PCGS or NGC.

Detecting Errors on 1998 Roosevelt Dimes

While proof coins are usually perfect, errors can still happen, and these are where the real money is found. Because the San Francisco Mint has such high quality control, an error on a 1998-S is extremely Rare. However, collectors often look for Broadstrikes (where the coin is slightly larger because it was struck without the retaining collar) or Off-center strikes.

On the more common 1998-P (Philadelphia) and 1998-D (Denver) dimes, you might find “Double Die” errors. Look closely at the lettering in “IBERTY” or the date. If you see a faint second set of numbers or letters overlapping the first, you may have found a valuable error. Even a minor doubling can turn a 10-cent coin into a $20 or $50 prize.

Before you get too excited and head to a coin shop, make sure to clean your coin properly—which, in the numismatic world, usually means don’t clean it at all. Scrubbing a proof coin with a cloth can ruin its “Deep Cameo” finish instantly, dropping its value to face value. Always handle your 1998-S by the edges to avoid leaving fingerprints.

How to Sell Your 1998 Proof Dime

If you’ve checked your coin and decided it’s a high-grade 1998-S, you have several options for selling. For coins worth under $20, online marketplaces like eBay are often the best bet. There is a constant demand from collectors looking to fill holes in their Roosevelt Dime albums. Be sure to take clear, well-lit photos that show the “S” mint mark and the mirror finish.

For coins that you suspect might be a “Perfect 70” (PR70), you might consider professional grading. A PR70 1998-S can sell for over $100 at professional auction houses. However, keep in mind that grading costs around $30-$50 per coin, so only send it in if you are confident in its flawless state.

Using tools like the CoinHix app can help you gauge whether the investment in grading is worth it. Most casual hunters find that keepings these coins in a simple cardboard “2×2” holder is the best way to preserve the 1998-S Roosevelt Dime value for the future. Whether you keep it as a lucky charm or sell it to a fellow enthusiast, it remains a beautiful piece of American history.

Frequently Asked Questions

Q: Is the 1998-S Dime made of silver?

A: No, the standard 1998-S Proof Dime is made of a copper-nickel clad composition. While the Mint does produce silver proof sets, the vast majority of 1998-S dimes found today are the standard clad version. You can tell the difference by looking at the edge; if you see a copper stripe, it is clad.

Q: How can I tell if my 1998 dime is a proof?

A: Look for two things: the “S” mint mark and a mirror-like finish. Regular 1998 dimes from Philadelphia (P) or Denver (D) have a duller, satin-like finish and were made for general circulation.

Q: Can I find a 1998-S dime in my pocket change?

A: It is very rare, but it does happen. Sometimes people break open proof sets to spend the money, or someone inherits a collection and doesn’t realize the “S” coins are special. These are called “Circulated Proofs” and are usually worth about $1 to $2.

Q: What is the highest price ever paid for a 1998 Roosevelt Dime?

A: High-grade specimens, particularly those with rare errors or perfect PR70 DCAM grades, have been known to sell for over $150 at specialty auctions, though most trade in the $5 to $15 range.
