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

    In my opinion, see that pitted look? It's probably had been in the ground for some tome. Or, it was a victim of some sort of acidic or chemical bath.

    Pitting is usually an indication the coin was subject to being in the ground or expose to the environment for quite some time.

    Acid or chemical treated coins usually have very little rim left and there are ravines where the was ate at the metal and it flowed over the rim edge.

      Ok I can accept that explanation for the pitting and edge wear but almost 1 1/2 grams off the weight?

        I know it seems far fetched, but I personally have seen my fair share of environmentally damaged coins. I suggest laying this next to a other nickel and seeing if one is higher than the other. Things to also note on this coin is the lack of a good solid strike. It looks heavily worn, and environmental issues will look like this.

        You could open a post on this forum on the main forum page under coneca services. Go to the examinations area and provide the best photos and a good
        Description of what you are seeing. Best to have as much data in one post than to wait for multiple conversations since these take time. In time, one of the CONECA staff members should respond with their opinion. They are volunteers, so it may take some time to respond.
