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

    You really shouldn't waste your time on such environmentally damaged coins, Get a box of coins from the bank and see if better conditioned ones are faster to search through. The understanding on how working Die`s are made will preclude any notion of there being a "face" or lions and tigers and bears on coins from the mint.

      Yes environmental damage. Severe pitting. It's been in the ground or was eaten up by caustic, acid or chemicals.

        Did you notice the exact Material on the back and the different patterns. I get that it's chewed up but there's also something else on it if its too chewed up to be something I understand but there's something else to it.

            Lets think about this...if there is something else on it and is chewed up, that something else came from the coins life in the wild, not from the mint.
            And that's all there is to it.

                All I can do for you is give you the standard of what coins should be when leaving the mint, anything added to a coin after that fact will be environmental PMD.
