If you are referring to a Washington Quarter that was minted from 1932-1964, it contains: 90% silver and 10% copper.

If it was minted from 1965 to the present, the composition is: 2 outer layers of 75% copper and 25% nickel bonded to a pure copper core, for an overall percentage of about 92% copper and 8% nickel.
