This a great question but I need clarification - are you referring to the Seated Liberty Quarter, the Barber Quarter, the Standing Liberty Quarter, or the Washington Quarter? If you are referring to the Washington Quarter, please provide to me the date of the coin since these quarters were composed of different alloys.
Up to 1964, quarters (as well as dimes, halves, and dollars prior to 1935) were made of an alloy of 90% silver and 10% copper. Rising silver prices forced the mint to switch in 1965 to a "sandwich" composed of outer layers of 25% nickel and 75% copper bonded to a core of pure copper.
From 1965 to 1969 half dollars still had a small amount of silver in them but in 1971 they were changed to the same sandwich metals. Dollars were also made the same way until 2000, when the current gold-colored brass metal was used.
The last year the American half dollar, quarter, or dime where made of silver, for general circulation, was 1964.
