All circulating quarters dated 1965 and later are made of copper-nickel. They don't contain any silver, so they're only worth 25 cents if you found it in change. All of these coins have a P or D mint mark next to the tail of Washington's wig
If your quarter has an S mint mark instead of a P or D and it doesn't have the normal copper core (check its edge) you may have a specially-made "Prestige Proof" coin. Prestige Proof dimes, quarters, and half dollars are made from the same 90% silver alloy used in those denominations before 1965.
To have its full value, a Prestige Proof coin should be in its original or other protective packaging. As of 09/2011 prices run from around $8 up to $15 depending on quality. If the coin was removed from its holder and was spent, its value as a collectible has been mostly destroyed but it's still worth about $8 for its silver content.
Neither the US nor Canada have struck circulating silver coins since the 1960s. If your coin is a collector's issue such as a US Prestige Proof, please post a new, separate question with more details.
The simple answer is that any US quarter dated 1964 or earlier is worth many times its face value because these coins were made of 90% silver. However if a quarter is older than roughly the late 1930s / early 1940s its collector value may be higher than its silver value but that depends on the coin's specific date, condition, and mint mark. For that you have to look at a values guide such as the Red Book, PCGS.com, Numismedia.com, etc.

The Mint has never made gold quarters. If you have a gold quarter then it has been plated which destroys the numismatic value of the coin. Its value is 25 cents plus the value of the little bit of gold they used to plate it. Some chemicals can cause the quarter to turn different colors. This also does not enhance the value of the coin.
Value depends on the degree of rotation, if you can take it to a coin show and find a dealer that sells errors for a idea of value.
The silver value is about $6.00. NOTE: The US has never made a pure silver quarter, they are 90% silver & 10% copper.
Pre-1965 US quarters are 90% silver with a value of about $2.50 just for the silver.
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.
Unless it's Proof, it's just a quarter.
A 1942 Washington quarter is common. If it has any wear, the value is just for the silver, about $3.50.
about $6.50-$7.50
If you mean the value of a US 90% silver quarter? Minimum value, as of 6-4-11, is about $6.56.The collectible value depends on date, grade and mintmark if any.
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.
Sorry! The US mint never made solid silver coins.
No 1972 US quarters have silver in them, the last year for silver quarters was 1964. so spend it
You don't have a pure silver quarter as the US has never minted a pure silver (99.9% pure or higher) silver quarter. Instead what you have is a 90% silver quarter which would be dated 1964 or prior. The value depends on a number of factors including the date, the mintmark and the condition. But a silver quarter is worth $5-6 in scrap silver regardless of type or condition, however some quarters can be worth significantly more.
The coin is worth about $3.25 just for the silver, the collectible value depends on how much wear the coin has and if it has a mintmark. And just so you know, it's spelled QUARTER.
