I have a well done 1916-D Merc that is counterfeit. I also have a genuine 1916-D slabbed in my safe. I plugged the hole in my Merc book with the counterfeit piece. I have no intent whatsoever of misleading anyone. I am quite the opposite sort of person. But if I depart this party tomorrow, my family will disperse my collection and now I am thinking that may lead a buyer to believe the coins my family is selling may be bogus. And if I leave the hole empty in the book, my ADD will go nuts..... Why do I make myself crazy with these kinds of thoughts????
