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

    Weak strike or post mint damage/alteration?

    Pulled this 80's Kennedy half while going through a bag. I believe it is a weak strike but have not personally seen many.

    Details are left in the center but are very week, i.e. hair on kennedy, feathers on the eagle. The weakness seems uniform and I didn't note any lines or whorls as if it had been altered.

    Any opinions are appreciated.

    This coin was altered outside the Mint. A genuine weak strike would have an entirely different appearance. Also, the proto-rim of the original planchet would be present. Yours lacks any trace of a proto-rim.
