You have to inspect your coin carefully. If it has a P or D mint mark, it's made of copper-nickel, not silver and is only worth 25¢. If it has an S mint mark and a copper-colored edge it's a copper-nickel proof coin worth maybe $2 to $10 depending on its quality. If it's in a holder labelled "Prestige Proof", then it IS a 90% silver coin. These were made for collectors and sell for $3 to $12 depending on quality and which state is depicted.

If it has an S mint mark and a copper-colored edge it's a copper-nickel proof coin worth maybe $2 to $11 depending on its quality. If it's in a holder labelled "Prestige Proof", then it IS a silver coin, but it's not solid silver. U.S. silver coins have at least 10% copper in them. These were made for collectors and sell for $3 to $15 depending on quality and which state is depicted.
If it has an S mint mark and a whitish color, it's made of copper and silver. If it has a D mint mark above the date or no mint mark (Phila.) it's actually made of copper and nickel. Please see the Related Question for more.
See if it has an "S" mint mark. If it does then it's a mint proof and it will be silver clad. No "S", no silver.
All circulating quarters dated 1965 and later, and most proof quarters, are made of copper-nickel. They don't contain any silver. If you found it in change and it has a D or P mint mark, it's only worth 25 cents. If your coin has an S mint mark, it's a proof coin that was made for sale to collectors. If it has a copper-colored edge it's also made of copper-nickel and might sell for $2 to $10 as of 05/2010. If it's in a special holder labelled "Prestige Proof", then it IS a silver coin and is worth $8 to $17.
