It’s a nice piece of Error coin history I thought would others may find interesting. C.O.N.E. Their motto is Sharing Information. I’ll let the register introduce itself. The pages are in an 8½ x 5½ format, are kinda stiff with a smooth finish. Mostly a list of common errors like die chips, die crack, partly filled die, but also has RPM’s , Clashed Dies & Doubled. There is 86 pages of Lincoln cents. Only 1.2 pages for the Kennedy Half and 1964 is the only date listed for it. There is also a few pages in the back listing some foreign coins. I can take pics of any queries about certain date / coin. Enjoy and be safe.
