Hi Peter, Thanks for the welcome, and tho a newbie to the forum and technical jargon ,my copy of Krause is the 1991 centennial edition, and my very first coin IS one of the rarest coins ( which I do not have the correct title for ) . It is a gold roman 'Otho'. I'm a lifelong collector, and closer to the end than the beginning. I don't think it's a turkey, I got it a few years back from another collector who had the finest Geo III tertio I'd ever seen ( which was graded,he mentioned Van Roekel...). Is there any way to put up a full size pic of it? As you say it is highly desirable, and if you look at the profile pic .... It's kinda minty! I don't understand the comment about the 'crown elite'. Another query I have is how to authenticate an 1887 proof crown? It's physical properties ( weight , diam and magnetic ) are correct , but it's never convinced me. How would I tell, and how thick should it be? Thanks guys, Tony
