@JCB. You should start a new thread about your Kennedy Half. I'm not trying to embarrass you or pick on you. Since you're relatively new on this site I'll try to explain it. You "hijacked" another members thread. This is considered impolite. It has nothing to do with the OP's topic. You'll get more replies with your own thread. Also, what are you asking about the coin?
You can't delete it, so don't worry about it. Just be careful in the future about what you post and where, and by all means, keep posting. The more you post, the more you'll learn. Thanks for posting, and especially, Thanks for being receptive to friendly "constructive criticism".
