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

            Yes, this is post mint damage. It's been in the ground more than likely. Or, as others have suggested, acid treated. It's in rough condition. The pitted surface usually means it's been In the ground. The mushy looking appearance means it could have been exposed to an acid based substance. The raised areas since they are on both sides, usually means it was exposed to high heat. In any event, all of those possibilities are post mint damage.
