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

  • Planchet cracks?

    I carefully studied 1000+ new Salt River Bay 2020 P quarters from new rolls. When I found the 1st of these marks I was thinking die crack but as I found similar marks in other places it no longer made sense. Would you suspect planchet cracks? I struggle to be able to tell if the mark is minus or + material (valley or mountain). Your thoughts greatly appreciated.

    I am not positive, but they are either minor die scratches/gouges on the die or minute flaws in the planchet. I don't think either rise to a point of collectability.
