It depends on when it was minted. Modern dimes don't contain any silver, but up till 1964 all US dimes were made of an alloy of 90% silver and 10% copper.
When the price of silver shot up in the 1960s the Mint was forced to remove silver from circulating coins, so all circulating dimes and quarters dated 1965 and later, and halves and dollars dated 1971 and later, have no silver in them.
A 1935 US dime should be made of 90% silver and 10% copper. You can check the edge of the coin for a visible silver coloration. Alternatively, you can use a magnet - silver is not magnetic, so if the dime does not stick to the magnet, it is likely silver.
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.
A 1946 dime contains 90% silver and 10% copper. This composition is known as "coin silver" and was used in dimes, quarters, and half dollars in the United States prior to 1965.
If your dime is silver, it will have a different composition compared to the current dimes. Silver dimes were minted before 1965 and contain 90% silver and 10% copper. You can check the year and mint mark on the dime to determine if it is a silver dime.
There is no silver in a 1990 US dime.
No, no US dimes dated 1976 contain any silver at all.
If the coin has any wear the value is for the silver, about $2.00
If it is a US dime, it isn't silver. Silver stopped being used in dimes after 1964, so any dime dated 1965 or later is struck in copper-nickel and are only worth face value.
If it's a US dime dated 1964 or before it's silver
1964 was the last year US dimes for general circulation had silver in them however, the silver dime lives on in the silver proof set series issued by the US Mint.
what is the value for an American 1909 silver dime
Nothing. There is no such thing. The most silver any dime has is 90%. This is most likely what you have.
A 1935 US dime should be made of 90% silver and 10% copper. You can check the edge of the coin for a visible silver coloration. Alternatively, you can use a magnet - silver is not magnetic, so if the dime does not stick to the magnet, it is likely silver.
