It is my undrstanding that the 90% silver Washington quarter dollars were minted through 1964. Clad coins and silver proofs began in 1965. My information comes from " The Official Red Book - A Guide Book of United States Coins 2012 " by R.S. Yeoman edited by Kenneth Bressett - 65th Edition published by Whitman Publishing. Thank you for you interest.
