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

    How would this kind of pitting occur?
    It's hard to tell if it's on before or after the strike. How would one go about telling the difference please?

    In my opinion, it's been in circulation.
    It looks like it's been in the ground.
    This is usually called environmental damage.

    It was probably in the ground for a while. Some one either saw it laying on the surface of the ground or found it with a metal detector.

    The only good pitting if you will, that I have seen was on a few select years of Morgan Dollars. Some had pitting due to rust. Some had pitting due to acid treatment done to the working die.

    Vamworld.com might have more info on the pitted Morgan dollar dies.
