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

  • Beautiful corner clip

    These are hard to come by in any year:

    Oddly, they always seem to occur on quarters.

    question

    Query:

    I've never seen a corner clip before, do they always appear so far out of square? If so, why?

      Hi Mike,

      Educate me a little. Even on a corner clip, shoudn't the details get a little fuzzy as they approach the edge?

      This one looks a little funky to me, but I havent seen too many of these.

      Thanks,
      Bill

        It's genuine because there is clear metal flow in the LI of LIBERTY and because there is an enormous Blakesley effect (flattening of the rim) opposite the clip. The angle of a corner clip is always obtuse, as seen here. Evidently, this is because the leading edge of the coin metal strip is cut at an angle for easier feeding, like a French-cut green bean. The tip of the strip is an acute angle, while farther back you find an obtuse angle where the cut meets the intact strip. While there is no testimonial evidence to back this up, it makes perfect sense.
