All U.S. quarters dated 1964 or earlier contain 90% silver and 10% copper.
The 1950 US quarter is 90% silver and 10% copper.
A quarter is made of 91.67% copper and 8.33% nickel. However, before 1965 quarters were made of silver.
The 1962 quarter is composed of 91.67% copper and 8.33% nickel, so it is not silver. To check if a quarter is silver, you can use a magnet - if it sticks, it is not silver; if it doesn't, there's a higher chance it is silver. You can also look for the coin's mint mark on the back above the "E" in "QUARTER" to determine its composition.
If it's a US quarter minted in 1965 or later, it's not silver (there are silver coins minted in "proof sets", but these came in a special labeled display case; you're not going to find one in pocket change). US quarters minted in 1964 or before were partly (about 90%, I think) silver.
If it is a US dime, quarter or half dollar dated 1964 or earlier, it is silver. If it is a US half dollar dated 1965-1970 it is 40% silver, if it is a US nickel from 1942-1945 AND has a large mint-mark (either a P, D or S) over the Monticello it is 35% silver.There are some US proof coinage in modern years that are silver, but those should be in a protective mint case and should say US silver proof set.
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.

First off, they are not sterling silver, sterling silver is 92.5% pure silver, most silver US coins are 90% silver and 10% copper, known occasionally as "coin silver". In average circulated condition, the coin is only worth its silver content, at the time of writing, it is about $5.50 in silver content. If it is in mint-state or otherwise very good condition, it might be worth more than just its silver content if you can find a collector.
A US quarter dated 1915 does contain 90% silver, so yes it is silver
None. It's pure nickel. Canada hung onto silver in its coins a bit longer than the US but stopped by mid-1968.
No circulating US silver coins were made of pure silver. It's too soft. The composition is .900 silver & .100 copper to make the coins hard enough to resist wear. Please see the Related Question for more information.
