Is there a 1967 silver us quarter?

Answer 1

All circulation quarters minted in 1965 and later are made of copper-nickel, just like dimes dated 1965 and later, and half dollars dated 1971 and later, as well.

As far as values, anything you find in change with those dates will be worth face value only. Uncirculated ones will can be worth a couple of times face value.
