It is unlikely that you have a clad 1964 quarter, all quarters dated 1964 should be 90% silver, not the copper-nickel clad of 1965-present. Look on the rim of your coin, if it is a solid color (usually solid white but silver tones easily to different colors) it is silver, if it has a line of copper through it it is clad (compare it with a quarter from your pocket change). If it is clad, it is an error and worth quite a bit of money. If it is silver it is worth about $6 for the silver content.
