Kennedy 1964 - what is this?
My late grandfather left me Kennedy 1964 silver half dollar coin. I ran on it recently and I noticed something unusual on it's surface. It's hard to see in the naked eye, but it seems it's above the coin surface. It can be seen between "L" and "I", approximately on 9.45 clock position. Any ideas? Thanks!
