Understanding the 1988-S Roosevelt Dime Production
The “S” mint mark on your 1988 dime signifies that it was struck at the San Francisco Mint. Unlike the dimes you find in your pocket change from Philadelphia (P) or Denver (D), the San Francisco Mint specifically produced “Proof” coins in 1988. These were not intended for general circulation. Instead, they were sold in official sets to collectors. If you’ve found one in a jar of loose change, it likely escaped from a broken collection.
To ensure you aren’t misidentifying your find, using a top coin identifier and value app can help you confirm the mint mark and strike type instantly. CoinKnow is a great tool for this, as it distinguishes between the frosted finish of a Proof and the shiny but flat finish of a business strike. The San Francisco Mint produced exactly 3,262,948 of these dimes in 1988, which sounds like a lot, but is actually quite low compared to the billions of circulating dimes made that year.
Because these was struck on polished planchets using special dies, the 1988-S dime features a mirror-like background and a frosted appearance on the portrait of Franklin D. Roosevelt. This “Deep Cameo” effect is what collectors look for. If your coin looks exceptionally shiny, you are likely holding a piece that was originally part of a 1988 United States Mint Proof Set.

Grading and the Impact on 1988 Proof Dime Value
In the world of coin collecting, condition is everything. A 1988-S dime is graded on a scale from 1 to 70. Since these were handled with care by the mint, most survive in high grades. A grade of PR 65 is considered a standard “Gem” Proof, while a PR 70 is considered perfect. Even a tiny hairline scratch visible only under a microscope can drop the value from $50 down to $5.

Many collectors look at the 1988 dime auction records and price trends to decide if their coin is worth professional grading. Professional grading by services like PCGS or NGC can cost $20-$50 per coin. For a 1988-S dime, it is usually only worth the investment if the coin appears to be a flawless PR 70.
If you are unsure of the grade, CoinKnow can provide high-resolution comparisons to help you spot flaws. Most 1988-S dimes found in “the wild” (outside of their original plastic cases) will have minor abrasions. These “impaired proofs” generally trade for closer to their face value or a small premium of $1 to $2, as serious collectors prefer coins that have never been touched by human hands.

Identifying 1988-S Roosevelt Dime Varieties and Errors
Error hunters are always on the lookout for mistakes made during the minting process. While the 1988-S Roosevelt Dime is known for its high quality, occasional errors do slip through. Common errors found in 1980s dimes include off-center strikes, clipped planchets, or “doubled dies.” A doubled die occurs when the coin is struck by a die that has a misaligned secondary image.
On a 1988-S dime, you would look for doubling in the letters of “LIBERTY” or the date “1988.” However, do not confuse “machine doubling” with a true doubled die. Machine doubling is caused by the coin vibrating during the strike and does not add value. For more specific details on what to look for, you can check the 1988 dime rarity and minting error guide to see if your coin matches known varieties.
If you find a 1988-S dime that looks “wrong”—perhaps the rim is too thick on one side or the “S” mint mark is missing—you might have a valuable rarity. Using the CoinKnow app to scan your coin can help identify these subtle anomalies that the naked eye might miss. True errors on Proof coins are quite rare because the Mint’s quality control for Proof sets is much higher than for standard pocket change.

Composition and Silver Content: Is It Silver?
One of the most common questions people ask when they find an old-looking dime is, “Is it silver?” For the 1988-S Roosevelt Dime, the answer is no. The US Mint stopped using 90% silver for dimes intended for circulation in 1964. The 1988-S Proof Dime is composed of a “clad” sandwich: 75% copper and 25% nickel over a pure copper core.
You can easily verify this by looking at the edge of the coin. If you see a distinct copper-colored stripe, it is a clad coin. While the Silver Proof sets became a regular offering in 1992, the sets in 1988 were exclusively copper-nickel. This means the value of the 1988-S dime is purely based on its numismatic (collector) value rather than its “melt” value.
Even without silver content, these coins are popular for “Year Sets.” People born in 1988 often buy estos dimes as anniversary or birthday gifts. This consistent demand keeps the price of high-grade 1988-S dimes stable. If you are starting a collection, the 1988-S is an affordable way to own a beautiful example of American coinage without spending hundreds of dollars.

Selling Your 1988-S Roosevelt Dime
If you’ve decided to sell your 1988-S dime, you have several options. Because the individual value is relatively low (between $3 and $15 for most), selling on eBay is the most common route. However, keep in mind that shipping costs and seller fees might eat up most of your profit. Often, it is better to keep the coin as part of a larger collection or sell it as part of a complete 1988 Proof set.
Local coin shops are another option. A dealer will typically offer you 50% to 60% of the retail value, as they need to make a profit. If you have a PR 70 (perfect condition) coin, you might consider a professional auction house, though this is rare for modern clad dimes.
Before selling, always check the current market sentiment. Prices for 1980s Proof coins can fluctuate based on collector interest. If you have several coins, using an app like CoinKnow to track your collection’s total value can help you decide when the right time to sell might be. Remember, the “S” mint mark is the key identifier that separates this coin from the common ones in your wallet.
FAQ
Q: Why does my 1988-S dime look different from a 1988-P dime?
A: The “S” stands for San Francisco and indicates it is a Proof coin. These are made using special polished dies and have a mirror-like finish, whereas the “P” (Philadelphia) coins are made for circulation and have a duller, matte finish.

Q: Is there a 1988-S Silver Dime?
A: No. The US Mint did not produce 90% silver Proof sets in 1988. Silver Proof sets were reintroduced in 1992. Any 1988-S dime you find will be made of copper and nickel.
Q: How can I tell if my 1988-S dime is a “Deep Cameo”?
A: A Deep Cameo (DCAM) coin has a very strong contrast between the design and the background. The portrait of Roosevelt will look white and “frosted,” while the flat background (field) will look like a dark, perfect mirror.
Q: What is the most a 1988-S Roosevelt Dime has ever sold for?
A: While most sell for under $20, perfect PR 70 DCAM specimens have occasionally sold at major auctions for $100 to $150, depending on the grading service and the “eye appeal” of the specific coin.
