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

  • 1957 D Double Die?

    I have a 1957 D Double Die that I cannot find in any guide book at all! I took it to a coin store just to verify the double die and was correct. Any idea where I can find info on this coin? Again, I have looked in many guides and cannot find it.

    Thanks

    Your coin looks more like mechanical doubling to me, looks like the M/M is involved in the action. If I'm wrong make it easy on the new guy.
