CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.

CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here

    Seeking Opinions on the Eisenhower Proof....

    I don't remember where I picked this coin up but I'm sure it was due to the toning. To make a long story short, after examining it closely, I saw what appears to have been mechanical doubling. However after further examination under my scope, I'm fairly confident that it is not mechanical doubling and I would like some opinions from the CONECA folks as to what would cause this. I pieced together some photos.

    And finally, the entire obverse:


    The letters and numbers appear to be totally unaffected which has me really curious.

    Interesting looking IKE. I agree with you that it's from doubled dies, it can effect some areas and not others.

      Ike proof

      Hi 19,

      I see strike doubling on LIBERTY and what appears to me as ejection doubling on Ikes portrait. The separation or "canyons" between the doubling seems too shallow for a doubled die. I'm no professional though.
