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

      That's a very interesting specimen i would say there's doubling on the date and the reverse of the coin. I don't really see any indications of DDD or MD on the coin There;s notching and seperation also ,but i'm not going to make a conclusion as of yet a posiible obverse and reverse DD

        The M and the E of AMERICA show what appears to be furrowing, but since the letters are not thickened, I doubt this is a doubled die. As best as I can tell, the letters of CENT show machine doubling. I see no doubling anywhere else.

            Hi Mile here;s a better picture of the date ,I go along with you it just doesn't seem like the correct seperation for a doubled die the seperation between letters are very thin , take a look at the date it also looks like the rest of the doubling through out the coin.

                I have seen this form of anomaly on quite a few Lincoln cents; it seems that the middle of the letter has collapsed leaving one to believe that it is a division line. However, the extra thickness that would accompany this division line to make it a doubled is just not there.

                  Thank you all again. Will remember that separation lines need to be accompanied by thickening to potentially be a DD.
