I hope you are not suggesting that I have manufactured this coin because that is completely false. I've had the coin since 1976 and I know it's not fake or manufactured. Several years ago I specifically went to a coin show in Manchester NH to have it looked at. I didn't bother having it graded because I'm not a collector.
@nancyb You have feedback from some very knowledgeable and well respected people in numismatics like @mikediamond and @CaptHenway Their opinions are very credible. I wouldn't worry too much about justifying it.
