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

    1966 DDO

    Gentlemen, here is something you don't see very often. I believe this is a true DDO. Take a look at the nose and chin along with the "WE" in the motto. Thanks for the feedback!

    It's machine doubling. Flat, marginal, the doubling cuts into the design. A doubled die is rounded and extends the image size.

      Jcuve.. Sorry, I think by looking at this DDO, I can see differences with the doubling. I believe the key here is the height of the of the doubling The first pic is a 1941 P penny with die doubling and the second is a 1934 Merc dime and that is machine doubling. Is this correct?

        You have a worn Lincoln 1941 DDO-002 and a 1934 Mercury Dime with machine doubling. None of this changes that the quarter you have also has machine doubling.
