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

  • 1957D-1C Missing and Added Material Error?

    The answer is almost always post-mint damage, but I've not seen added copper appear in addition to incuse errors. Might the increasing weakness of U-S-T in TRUST, suggest the strike partially was impeded by a object between the die and the planchet. Has anyone seen an error of this type before? Was this a bizarre welding accident?!

    Thanks all!

    Most likely environmental damage. There is no way this could happen in the minting process in the end just PMD.
