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.

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.
There are 5.625 grams of pure silver in every US quarter dated 1964 or prior.
The US never used pure silver in circulating coins. It's too soft.
