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

    2013 Lincoln Cent DDO?

    I'm seeing doubling on the lettering and date of this 2013 Lincoln Cent. I don't think it is machine doubling, but I'm still learning. I could not find similar doubling on Wexler's list, Varity Vista, or Copper Coins. Thanks for your time.

    Greetings, i am seeing Die Deterioration along with Machine Doubling + plating issues on both Obverse and Reverse, notice how the doubling on IGWT flows towards the rim?
    this is typical of the cavities of the devices breaking down along their edges and the metal then flows to the direction of least resistance, the edge.

    this may fall into other type of mechanical doubling, see here for more references, and lets see what other say as well.
