Every dime dated 1964 or earlier is worth at least $2.25, but some rare dimes are worth over $2,000! While often overlooked, dimes offer some of the most exciting finds in coin collecting. From 90% silver Roosevelt dimes to the iconic Mercury dime, your pocket change could be hiding a valuable treasure.
This comprehensive 2025 guide will show you exactly which dimes are worth serious money. Plus, we'll reveal how the Coinly app can help you identify these valuable dimes instantly with just a photo.
Why Are Some Dimes So Valuable?
The value of a dime is determined by its silver content, rarity, and condition.
Silver Content (Pre-1965)
All dimes minted in 1964 or earlier are composed of 90% silver. With silver prices at historic highs, this gives them a "melt value" far exceeding their 10-cent face value.
- Composition: 90% silver, 10% copper
- Silver Weight: 0.07234 troy ounces
- Current Melt Value (Jan 2025): $2.26 per dime
Rarity and Key Dates
Certain years had very low mintages, making them rare and sought-after by collectors. The mint mark (a small letter indicating where the coin was made) is crucial.
Minting Errors
Mistakes made during the minting process can create rare and valuable error coins.
Roosevelt Dimes (1946-Present)
While most Roosevelt dimes are common, some are valuable.
Silver Roosevelt Dimes (1946-1964)
All dimes from this period are 90% silver and worth at least $2.26 each.
- How to Identify: Check the date. If it's 1964 or earlier, it's silver. You can also check the edge—a silver dime has a solid silver stripe, while a modern clad dime has a copper-colored stripe.

How to Find and Identify Valuable Dimes
Where to Hunt
- Bank Rolls: The best method for searching large quantities. Ask for rolls of dimes at your local bank.
- Pocket Change: Get in the habit of checking every dime you receive.
- Coinstar Reject Trays: Silver dimes are often rejected by Coinstar machines because their weight is different from modern clad dimes.
- Estate Sales & Flea Markets: Look for old coin jars or albums.
Identification Tips
- Check the Date: Anything 1964 or earlier is 90% silver.
- Check the Edge: Look for the solid silver stripe. No copper means it's silver.
- Look for Mint Marks: On Roosevelt and Mercury dimes, the mint mark is on the reverse. On Barber dimes, it's on the reverse below the wreath.
- Use Magnification: A 10x magnifying glass is essential for spotting errors and varieties.
- Use the Coinly App: For instant, certain identification, nothing beats a quick photo scan with Coinly. The app's AI can spot key dates, errors, and estimate the coin's grade and value.
