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

    1919S Lincoln

    Why is this penny gold in color and are the letters and partial date due to grease build up on die? Also it weighs 2.87g if that matters.

    In my opinion, that looks like some serious pitting from environmental damage. It may have been in the ground for a period of time. If it was, it was found and cleaned. Or, it was a victim of some sort of acid based treatment. In any event, the patina was stripped off the coin.

        It's supposed to be one coin per thread. I answered the first one.
        I am just following the forum rules. If some one else want to answer its up to them.
