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

    Crazy Jefferson?

    I was wondering if anyone can tell me what happened to this 1977-P Jefferson Nickel. I do not think this happened at the mint. To me, it looks like a super-matte finish. I just want to know what would cause this. Both sides are like this, as is the rim. If it was a chemical, any ideas what kind. It looks like it was sand blasted with a mini sand blaster, with extremely fine sand. It also feels kind of slippery or smooth, but not smooth. I know that makes no sense, but that is kind of how it feels. Thanks.

    This appears to be PMD Post Mint Damage.This coin looks like it was in a dryer.

      Thanks Mr. Davis. I knew it was PMD, just didn't know what. That sounds very likely.

        It may have been sand blasted.
