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

  • 1974 JFK Half dollar Doubled, do I have something??

    Looking at my JFK's and found this. Do I have something and is it worth spending the 40 bucks to send it in? Does anyone know how much it might be worth? (there also seems to be so sort of tape on the back but no tape I've ever seen before. does anyone know what it might be?

    Minor machine doubling. No value attached to it.

      Hi,
      This is Strike Doubling (aka Machine or Mechanical Doubling). The reverse shows what appears to be clear tape over the coin or marks where there was once tape.
