Possibly. If your dime is dated 1965 or later and is thinner than a normal dime, it may be what's called a lamination error. That usually happens when the clad metal stock used to make planchets (coin blanks) is defective. Sometimes the cladding near the end of a roll of stock is missing so a few planchets will be struck from just the copper core without the normal outer layers of nickel-copper alloy.
Assuming that's what you have, as of 03/2011 a clad dime lamination error might sell for $6 to $10.
But if the dime is the same thickness and weight as a normal dime, you may have nothing more exciting than the results of a high-school chemistry experiment. Plating coins with copper is a typical exercise when studying the electromotive series and half-reactions.
In 1913, the US mint was producing Barber dimes. They were named after their designer Charles Barber. They contain 90% silver and 10% copper.
All US dimes minted before 1965 are 90% silver and 10% copper.
No. US Dimes dated 1965 and later, were all made from a copper-clad alloy. The dime you have is gold-plated.
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.
All circulating dimes dated 1965 and later are made of copper-nickel, not silver.
it is made out of a mixture of copper and nickel
A US dime is not magnetic. It is composed of 90% silver and 10% copper and neither of those metals are magnetic.
No, current US dimes are composed of 91.67% copper and the remainder is nickel
If it has been copper plated, it's still just a dime.

In 1913, the US mint was producing Barber dimes. They were named after their designer Charles Barber. They contain 90% silver and 10% copper.
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
A modern dime is 75% Copper, 25% Nickel
All US dimes minted before 1965 are 90% silver and 10% copper.
how much does it cost
There's no silver in the 1965 dime. It's mostly copper with a bit of nickel, and weighs 2.268 grams.
The value of a 2006 copper dime varies depending on its condition. In some cases this dime is worth about $0.15 and might be valued at up to about $1.
