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

  • 2005 Experimental Planchet?

    Were there any experimental planchets used in 2005 on the West Virginia Quarter that anyone knows about?

    The quarter weighs 5.870 grams, side looks darker than the usual circulated ones.

    As soon as I get my scanner hooked up I will scan a picture of the quarter.

    Thanks for any info on this

    I am not aware of any experimental or off-metal errors among West Virginia quarters.

        I haven't seen any experimental planchets later than New Jersey and Maryland.
