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

    Error coin or acid dipped?

    I found this coin while roll searching.The weight on this coin is 25 grams and seems more heavier than the normal zinc copper coated coins,that weighs in at 24 grams.

    You dropped a decimal point. A normal copper-plated zinc cent will weigh 2.5 grams. Judging from the bumps all over the surface, the copper plating was chemically stripped on your specimen.
