Something odd about these siver dollars.

On November 7, 2009 I was at a coin show in Edmonton AB with my father and I was going through a bin of silver dollars. While I looking through I noticed that on the 1939 silver dollars looked a little differet. The nose on a couple of them looked different. I asked around and it seemed like no one noticed it before. On Nov 11, 2009 I sent an email to the coin news to see if they had noticed it. I am currently waiting for a reply from them.
