Open the full calculator →A pre-1965 US dime — whether a Barber (1892–1916), Mercury (1916–1945) or Roosevelt (1946–1964) — weighs 2.5 grams and is 90% silver. That is 0.07234 troy ounces of pure silver per coin.
Mercury and Roosevelt dimes have the same silver content, so they have the same melt value; only their collector appeal differs. The live figure above is the intrinsic silver value of one dime.

Melt value is the value of the metal in the coin, ignoring any collector premium:
Where the fine-metal content is known, this simplifies to spot × 0.07234 oz. The live figure at the top of this page applies that formula to the current spot price.

A pre-1965 US dime contains 0.07234 troy ounces of pure silver (90% of its 2.5 g weight). Mercury and Roosevelt dimes are identical in silver content.
About 13.8 uncirculated dimes make one troy ounce of pure silver. Using the circulated dealer standard of 0.0715 oz per dime, it takes about 14 dimes.
No. The US stopped striking 90% silver dimes after 1964. Any dime dated 1965 or later is copper-nickel clad with no silver content.
Their melt value is identical. Mercury dimes can carry a higher collector premium in high grades, but a worn example of either is worth the same silver value.
