US dimes dated 1964 and earlier are 90% silver. That includes Roosevelt dimes (1946–1964), Mercury dimes (1916–1945), Barber dimes (1892–1916), and older Seated Liberty and Bust dimes. From 1965 onward, all circulation Roosevelt dimes switched to copper-nickel clad with no silver.
Silver Dime Date Guide
| Series | Years | Composition | ASW per coin |
|---|---|---|---|
| Roosevelt | 1946–1964 | 90% silver, 10% copper | 0.0723 ozt |
| Mercury (Winged Liberty Head) | 1916–1945 | 90% silver, 10% copper | 0.0723 ozt |
| Barber | 1892–1916 | 90% silver, 10% copper | 0.0723 ozt |
| Seated Liberty | 1837–1891 | 90% silver, 10% copper | 0.0723 ozt |
| Bust (Capped Bust, small) | 1828–1837 | 89.24% silver | slightly less |
| Roosevelt 1965–present | 1965–now | Copper-nickel clad | 0 |
Almost all silver dimes found in circulation or bulk bags are Roosevelt or Mercury dimes. Barber and older dimes are encountered less often and some carry collector premiums.
How Much Silver Is in a Dime?
A 90% silver dime weighs 2.50 grams. The calculation:
- Gross weight: 2.50 g
- Silver fraction: 90% = 2.25 g silver
- Convert to troy ounces: 2.25 g ÷ 31.1034768 g/ozt = 0.07234 ozt ASW
Rounded to the standard four-decimal figure: 0.0723 ozt ASW.
At spot prices of October 7, 2026 ($60.73/ozt):
Melt value = 0.0723 × $60.73 = $4.39

How to Identify a Silver Dime
Step 1 — Check the date. Any dime with a date of 1964 or earlier is silver. You do not need to identify the design series first.
Step 2 — Check the edge. Tilt the dime so you can see the narrow rim. A silver dime has a uniform bright-silver edge (reeded/milled). A clad dime shows a distinctive reddish-copper stripe running through the middle of the edge.
Step 3 — Listen (optional). Drop a silver dime from a few inches onto a hard surface. It rings with a clear, high-pitched tone. A clad coin thuds.
Worked Example: A Roll of Silver Dimes
A standard dime roll holds 50 coins. If all 50 are pre-1965:
| ASW per coin | 0.0723 ozt |
| Coins in roll | 50 |
| Total ASW | 3.615 ozt |
| Melt value at $60.73/ozt | $219.48 |
| Face value | $5.00 |
That roll is worth about 43.9 times its face value at October 7, 2026 spot prices.
Silver Dime Melt Values at a Glance

| 50 dimes (1 roll) | 3.615 ozt | $219.48 |
| 500 dimes ($50 face) | 36.15 ozt | $2,194.79 |

Key Dates That Exceed Melt Value
Most silver dimes sell at melt. A handful command significant collector premiums:
Mercury dimes (Winged Liberty Head):
- 1916-D: Extremely rare. Even worn examples sell for thousands of dollars.
- 1921 and 1921-D: Low mintage; circulated examples bring $30–$100+ over melt.
- 1926-S: Scarce in higher grades.
Barber dimes:
- 1894-S: One of the rarest US coins. Only 24 minted; not a junk silver coin.
- Most Barbers in Good grade trade near melt.
Roosevelt dimes:
- Common dates are all traded purely at melt. No Roosevelt dime key date is rare enough to create a large premium on circulated examples.
If a dime is old and heavily worn, it is still worth melt. Check unusual dates before selling in bulk.
Are Any Post-1964 Dimes Silver?
Two situations produce silver dimes dated after 1964:
-
Silver Proof Set Roosevelt dimes (1992–present): The US Mint sells an annual Silver Proof Set containing a 90% silver Roosevelt dime. These are proof coins with a mirrored finish, not circulation strikes. They contain the same 0.0723 ozt ASW as pre-1965 dimes.
-
Some special commemorative issues may contain silver, but dimes in everyday commerce from 1965 onward are uniformly clad.
None of these appear in change. If you pull a dime from pocket change dated after 1964, it is clad.
Mercury Dimes vs. Roosevelt Dimes: Any Difference in Silver Value?
Both series contain the same 0.0723 ozt ASW per coin (same weight, same 90% composition). The metal value is identical. The difference is aesthetic and, for certain dates, numismatic:
- Mercury dimes (designed by Adolph Weinman) are widely regarded as one of the most beautiful US coins and attract collector demand. Common dates 1934–1945 trade very close to melt.
- Roosevelt dimes (designed by John Sinnock) are the most recent and most common in circulation bags; easiest to buy in bulk near melt.
For stacking pure silver by the ounce, they are interchangeable. See what is junk silver for how all pre-1965 silver coins fit into the junk silver market.
Silver Dime vs. Clad Dime Side by Side
| Attribute | Silver dime (pre-1965) | Clad dime (1965–present) |
|---|---|---|
| Weight | 2.50 g | 2.27 g |
| Silver content | 2.25 g (0.0723 ozt) | 0 |
| Edge | Solid silver-white | Copper stripe visible |
| Melt value at $60.73/ozt | $4.39 | negligible |
Note the slight weight difference: silver dimes are heavier than clad dimes. A simple postal scale can confirm which you have if the edge is worn smooth on very old coins.
The coin melt value calculator handles any weight-based calculation for your stack.
How to Buy Silver Dimes
Silver dimes are one of the easiest entry points into precious-metals stacking because of their low per-unit cost (about $4.39 each at current spot prices). Options include:
- Local coin dealers: Sell Roosevelt and Mercury dimes by the roll (50 coins, $5 face) or in bulk bags. Common dates typically trade 5–10% over melt.
- Online bullion dealers: Often competitive on large bags ($50–$500 face). Compare price per face dollar or per troy ounce.
- Coin shows and estate sales: Can yield close-to-melt prices on common dates. Inspect for key dates before buying at bulk rates.
A practical entry lot: one 50-coin roll of Roosevelt dimes costs roughly $4.39 × 50 = $219.50 at melt plus any premium. That gives you 3.615 ozt of silver in recognizable, divisible form.
Storage and Handling
Standard dime tubes hold 50 coins. Label tubes with date range (e.g., “1946–1964 Roosevelt”) and store in a dry location. Toning on silver dimes is cosmetic and does not affect the metal content. Dealers price circulated 90% dimes on silver content alone.
