US quarters were never made of solid silver. They always contained about 10% copper so they wouldn't wear down too quickly in circulation.
Common date silver quarters (~1940 to 1964) are valuable mostly for their metal content. They contain about 0.18 of a troy ounce of silver so you'd need the current price of raw silver to get an idea of the melt value. While it's not normal WikiAnswers policy to say "use the internet", that's the best approach in this case. You can check a site such as kitco.com, CNNMoney, etc. for the latest spot prices.
For older coins, you need to know the date and mint mark to determine their collector value.
A US quarter has a face value of 25 cents.
Half dollars were never made of solid silver. It's far too soft to use in a circulating coin. US halves were made of 90% silver up till 1964, and 40% silver from 1965 to 1970. Please post a new question with the coin's date for more specific information.
Unless it's Proof, it's just a quarter.

Any silver (pre-1965) US quarter is currently worth at least $5 for its silver content. Then collector value above that depends on factors like the date and condition.

Silver prices have been dipping over the last few weeks, so the current melt value of a US silver quarter (minted before 1965) is a little under $6.
