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

  • Post mint damage or some type of clip/sheet edge?

    Do you think someone trimmed the edges of this penny or could this have come from the mint? I remember seeing someone cut through part of a penny in a scissor's sales demo one time... Impressive task for scissors but a tragedy for the penny

    yes, to me it looks like some one did it post mint. The angle photo looks like it was done not too long ago as the metal looks "fresh" and not 100+ years old.
    There is something called the Blakely's effect that I look for when looking for clipped planchets. Its looks sort of crumbled in the center of the curved clips and though this is straight, it seems unnatural. There is supposed to be an area of weakness on the strike since the coin does not fill the entire die.

    That metal, shouldn't be that shiny for 100+ years old. Tarnish, grime and handling should have dulled that down to almost unnoticeable.

    The cuts appear to be nearly perfect, and think of this - TYPICALLY if this is the edge of a metal sheet, you shouldn't have this combination of edges on a sheet. Any other combos would make sense, to make it a corner piece - but this one does not.

      Thats PMD. A straight clip parallel like that doesnt seem logical if you see how a sheet is punched out

        Thanks. I have some clips that I suspect are real and will post for continued education when they re-surface.
