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 Identification Please…

    Hello, I cannot remember for the life of me what this error is called? I checked on error-ref.com but couldn’t find it. It’s eating at me. Thanks!

    Not an error, PSD “Post Strike Damage”. Most likely done by a sheet metal cutter.

      agree PMD by wire cutters or sheet metal snios

        Thank you JC and PNWMAKES. See, initially I sad the same thing. Then I saw some where that this can also be damage done somehow during the striking process. This is why I brought it to you because I’m sure I saw a video on this type of damage saying many over look it as PMD but that in fact this is done at the mint. Maybe I can run across that video again. Thank you gentleman I appreciate your feedback!

          The metal pushed out past the rim tells me PMD. A coin struck through debris in a collar would be round and not have the metal flowing out. Unless it is a partial collar which is another error altogether.
