No, he didn't. But that is what he was talking about since he was only talking about circulation coinage.
Try and rmember that almost every one today writes books on something. Criminals in prison, murderers, movie stars, insane alysum people and just about anyone else. At coin shows there are usually talbes full of coin books. Go to a book store and note the shelves are full of books and some written by people that are completely nuts. So to say this guy is reputable because he wrote a book is like saying everyone that writes a book is OK.
