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

    ebay error

    There is a cent error posted on ebay, 300141668209, by 69mustang423, a person for whom this is a first listing. Is it possible that the coin displayed is authentic?

    It's quite authentic. It's an example of clashed dies (die clash, clash marks). The dies banged against each other when a planchet failed to be fed into the striking chamber. This transfers the image of one die to the other. It always requires two press malfunctions -- 1) failure for a planchet to be fed in, and 2) failure for minimum die clearance to be maintained.

      Okay and thanks, I understand, but why are there no clash marks on Lincoln's portrait?

        This is normal and expected. Remember that Lincoln's bust is raised on the coin and therefore recessed in the die face. Recessed areas are relatively protected from a clash. The field is the most vulnerable area.
