These links will help you with the cents. As for the Halves, if they are bank rolls, anything 1970 and older. Also look for the 1982 P mint halves. On the reverse look to see if there is no "FG" between the eagles tail and the right leg. Keep those. As for the 5, 10, 25 cents, I can't help you much there for I don't search those. Just check out what the coin mags and Red Book lists to get an idea of what to look for.
