Currently they are made out 91.67% copper and 8.33% nickel but before 1965 they were made out of 90% silver and 10% copper.
A 1975 Roosevelt Dime has the following composition: outer layers of 0.75 copper and 0.25 nickel bonded to a core of pure copper; the overall composition is about 93% copper and 7% nickel. The coin weighs 2.27 grams.
There's a list of all coin specifications at the U.S. Mint site:
You can check the composition of a 1948 dime using a magnet. If the dime is attracted to the magnet, it likely contains iron and is not pure silver. A pure silver dime will not be attracted to a magnet.
If your 1963 dime is silver, it will not have a copper band along the edge. Instead, the edge of a silver dime will appear silver in color and more uniform in appearance. You can also use a magnet to test its composition - silver dimes are not magnetic.
It is 90% silver and contains a little over 2 grams of silver.

A 1964 dime is made of 90% silver and 10% copper, known as a "silver dime" because of its silver content. These dimes were the last to be minted with silver before the composition changed to a copper-nickel alloy in 1965.
There was never a dime popularly called a "war dime". That term was usually applied only to those coins whose metal composition was changed due to wartime metal shortages - e.g. cents in the US and nickels in the US and Canada. Because dimes were mostly silver their composition wasn't changed, so regardless of date they're just dimes. Please see the Related Question for more information.
From 1837 to 1964 all US dimes had the same composition of .900 silver & .100 copper
The volume of a U.S. dime is approximately 0.36 cubic centimeters (cm³). This small coin has a diameter of 1.8 centimeters and a thickness of 1.35 millimeters. Its composition mainly includes copper and nickel, contributing to its overall size and volume.
Please check your pocket change. You should be able to find dimes dating back to 1965 when the current copper-nickel composition was introduced. Any ordinary dime with that date or later that you find in change will be worth face value only.

A quarter is heavier than a dime because it is made of a larger amount of metal. Quarters are larger in size and have a greater weight due to their composition of 91.67% copper and 8.33% nickel, while dimes are smaller and made of 91.67% copper and 8.33% nickel.
