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

    Help with a 71S DDR Proof Lincoln Cent

    I found this doubling on a 71S Proof Lincoln Cent. There is light notching on OF AMERICA, a light spread on the designers's initials, and very light notching and extra thickness on the BU of PLURIBUS, see attached photos (this doubling is so light it is very hard to get photos, especally in a proof set).

    I noticed that there are no listings for a 71S DDR in the CONECA listings or on Copper Coins. I was wondering if anyone thinks there might be something to this one...or would it be to minor to be concerned about.

    Thank You,
    Larry Nienaber

    Larry: I can see the light separation on the designer initials, and also the notching of E and R, your photos turned out well I think, Mr Wiles should have a look at this one , a doubled die is a doubled die.

      Larry:
      Your photos indeed are very good. The splits confirm it to be a doubled die. However, it is just too minor to list.

        Good eyes! Nice find and photos!
        It is minor, but maybe Wexler, who is out to list everything, would take a look at it.
