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

  • 1985 D Roosevelt Dime

    Two color Roosevelt Dime found in pocket change, OBv is a dull silver color and the REv is a copper color. Reeds are two tones. when viewed from the side of the coin, reeds are split into two colors. The side of the coin that is copper - the reeds are the same color. The side of the coin that is silver looking, the reeds are the same color as the obverse side. Can someone tell me if this happens to coins all the time or can you tell me what kind of coin error (if any), this is?

    There are a couple of possibilities for coins like this. The first is that it is missing the clad layer on one side of the coin, and the second is that it is damage from coming in contact with a corrosive liquid. Based on what I am seeing, I believe this is damage from sitting in a corrosive liquid.

      Beach sand will also layer clad coins with a thin copper like layer of something (I do not know what it is). From the photos I cannot tell if the back is corroded or coated with something.
