Welcome to the forum Chip! I would start a separate thread asking for a grade. It has some damage on the obverse but not bad IMHO. I would say it's an MS 63/64. There was little over a million of these produced, I don't think rare but a hard one to find. I'm guessing, if real and I am guessing grade correctly, $450 to $900. Appeal has a lot to do with price. Again, start it's own thread, you will get some replies from the experts, I'm a rookie myself.
