Is there a John F. Kennedy silver quarter?

Answer 1

No. JFK's picture is on the half dollar.

The only 90% silver JFK halves were made in 1964.

Halves dated 1965 to 1969 are 40% silver.

Halves dated 1971 and later are copper-nickel and are only worth face value.

Answer 2

Yes, there is a John F. Kennedy silver half dollar but not a quarter. Kennedy half dollars were minted in 90% silver in 1964, and 40% silver from 1965 to 1970. Silver quarters were last minted in 1964 before switching to a copper-nickel composition.
