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

    Define common. Common compared to ?
    Each is unique. We are not able to see the whole coin, so we have to assume it is a struck through grease. Or, it could be from post mint damage from a coin counter.

      In common I mean in comparison to the 1/2 billion coins minted are these grease filled die errors in high percentage of that number or a low (rare) quantity? I’m sure there are others. Thank you in advance IMG_2726.jpg

        It's pretty minor to tell you the truth.
        Unless the grease gets a lot of the devices and it looks dramatic, In my opinion, it is not worth much.
