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

  • 1776-1976 Eisenhower silver planchet with copper showing

    Opened a Silver Uncirculated 1776-1976 three coin set in a flat pack, and found the Dollar showing copper color around the top 1/4 of the edge of the coin. I thought, and the other two sets have only silver showing. I'm thinking this is a planchet error. Am I right or wrong. your assistance is requested.

    You'll have to weight the coin.

    Silver will come in at 11.5 grams (+/-)

    CnClad will come in at 11.3 grams (+/-)

    If it comes in at the CnClad weight along with an S Mint mark - Winner!

      Good Tips above, but you also need to remember that the 40% silver coins are still a clad coin- 80/20 Ag/Cu outer layers bonded to a 20/80 Ag/Cu core.
      As will happen with many of the 40% Kennedy's, the core will oxidize differently than the silver clad layers, giving the edges a dark or copper colored ring.

        The color was the result of toning. Thanks.
