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

    We have added some interesting examples are in the search for more. Check out the site.

    Here is an example of an Atypical Die Clash ADC-1C-1977-01: it has a large CUD at K10-11, a rim CUD at K7 and it shows a Finned Rim from K3-7.

      Are these considered die clashes? I would like your opinion. If you need better pics let me know. I have many similiar coins. I am learning what to look for.

          Large Lump in memorial

          Are large lumps considered die clashes or has something been embedded in between the coin when minted
          I have three coins with large lumps on the left side inside the memorial
          I have a pic for you. If unable to see I have other pics.

          I also have several that seem to have a part of lincolns jacket showing on the left side inside the memorial. I will find and upload one for you.

            While some interpret this as a clash mark of the back of Lincoln's coat, I have my doubts. It's too blunt and there's too much deformation in the columns and roof. I suspect it's a die dent or a form of die deformation.
