You would have to post a Kennedy Half or a coin dated 1968 as stated in the first post, same denominations don't count.
64 kennedy half to 64 walking half doesn't work. 64 kennedy to 64 cent does. 64 lincoln memorial cent to 98 lincoln memorial cent works.
1964 half dollar to 1943 half doesn't work either does it?He probaly just skipped over yours because you messed up the order first
