Paul: It is easy to separate silver quarters, dimes and half dollars from
the post 1964 copper nickle clad coins by looking at the color. To teach
this to yourself put 10 quarters from 1964 or earlier into a pile with 10
from 1965 or later. Mix them up. You will be surprised how easy it is to
tell the difference. You can even see the color difference after you have
gone cross-eyed. Halfs are tougher since 1965 to 1970 are 40% silver and
worth pulling out of circulation. Good Luck!
