No 1964 silver quarter should have a copper layer and they all should be 90% silver, although it is possible that your quarter has tarnished or toned odd and just appeared to look non-silver. Both copper-nickel clad and silver quarters were produced in the mid-1960s with the clad ones being dated 1965 and later while the silver ones were dated 1964, so theoretically it could be struck on a copper-nickel planchet. I would weigh the coin, a silver one should weigh about 6.25 grams (naturally a worn quarter would weigh less) while a copper-nickel one should weigh much less, about 5.67 grams.

How much would 1000 penny weigh?
A quarter of a pound.
