The 2018-S Roosevelt Dime is worth anywhere from $2 to $25 or more depending on its grade and type, with proof versions being the most sought-after by collectors. If you’ve come across one of these coins and are wondering whether it’s hiding real value, you’re in the right place — let’s break it all down in plain language.

What Makes the 2018-S Roosevelt Dime Different

Most Roosevelt dimes you’ll find in your change come from the Philadelphia (P) or Denver (D) mints. The 2018-S dime, however, was struck at the San Francisco Mint — and it was made exclusively for collectors, not for general circulation.

That “S” mintmark on the back of the coin (just to the left of the torch) is your first clue that this isn’t your average ten-cent piece. The San Francisco Mint produces both standard proof coins and silver proof coins, and the difference between the two matters quite a bit when it comes to value.

2018-S Roosevelt Dime Value by Type and Grade

There are two main versions of the 2018-S dime: the clad proof (made from copper-nickel) and the silver proof (made from 90% silver). Both are beautiful coins with sharp details and mirror-like fields, but the silver proof carries more intrinsic metal value on top of its collectible appeal.

Here’s a quick look at typical values for each type:

How to Tell If You Have a Silver or Clad 2018-S Dime

This is one of the most common questions people ask, and luckily it’s not too hard to figure out. The easiest way is to look at the edge of the coin.

A clad dime will show a visible copper-colored stripe running along the edge — that’s the copper core sandwiched between the outer nickel layers. A silver proof dime, on the other hand, will have a solid, uniform edge with no colored stripe whatsoever.

You can also check the packaging. Most 2018-S silver proof dimes were sold as part of the U.S. Mint’s Silver Proof Set, which came in a sealed presentation box. If your coin is still in its original mint packaging, that’s a strong sign of what you have.

CoinKnow is a handy app that lets you scan and identify coins on the spot, so if you’re unsure whether that edge looks copper or not, it can give you a quick second opinion along with value estimates.

Why Condition and Grading Matter So Much

With proof coins like the 2018-S Roosevelt dime, condition is everything. These coins were never meant to be spent — they were struck with specially polished dies on polished blanks to produce incredibly sharp, mirror-like finishes.

Even a tiny fingerprint or scratch can drop a proof coin’s grade from a perfect PR-70 down to a PR-68 or lower, which can significantly affect its value. Collectors and grading services like PCGS and NGC are very particular about this.

If you’re thinking about selling or getting your coin graded professionally, it’s worth checking detailed 2018 dime value information broken down by grade and condition so you know what to expect before you spend money on third-party grading fees.

Is the 2018-S Roosevelt Dime Worth Keeping or Selling

Honestly, for most people, the 2018-S dime is more of a keeper than a big money-maker. It’s not going to pay off your mortgage — but it’s a genuinely collectible piece of U.S. Mint history, especially in the silver proof version.

If you have the full 2018 Silver Proof Set intact and unopened, that set can fetch $35 to $60 or more on the secondary market. Individual coins removed from the packaging are worth less, since the presentation packaging adds to the collectibility.

CoinKnow makes it easy to track your collection’s value over time, log your coins by mint and grade, and get alerts when prices shift — all from your phone.

FAQ

Q: How much is a 2018-S Roosevelt dime worth today?
A: A 2018-S clad proof dime in average condition is worth around $3 to $6, while a perfect PR-70 deep cameo example can reach $25 or more. The silver proof version is worth more, often $15 to $50+ depending on grade.

Q: Is the 2018-S dime made of silver?
A: It depends on which version you have. The U.S. Mint made both a clad (copper-nickel) proof and a 90% silver proof in 2018. Check the edge of the coin — if there’s no copper stripe, you likely have the silver version.

Q: Can I find a 2018-S dime in everyday pocket change?
