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

    Nothing short of PMD, Post Mint Damage, this did not happen in a US mint while being struck as a coin. There are an infinitesimal amount of different things people will do to coins, and is only limited by Imagination.

      In my opinion, more than likely an acid treated coin. It could have been ketchup, or some other stronger acid or chemical. It's not worth anything, probably less than a cent now. I suggest being a tad careful handling that coin, it's probably has some residue on it.

          I did not read any comments. I just concluded. Upon first glance that a cement mixer was in involved. Now i will read comments.
