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

  • Penny struck on dime planchette

    I found a 1999 D penny with copper coating. Copper is coming off and it looks silver, but in the pictures it looks white under the copper. Any suggestions, Macy

    I am not a paid member. I believe this coin to be composed normaly. The zinc is wearing through. It should weigh 2.5 grm. Maybee less with wear.
