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

    1990 reverse grease die

    I've got some questions about this one.#1 What are the little spots of extra metal called on the obverse, and do you think the ear looks like i'ts doubled down the out side edge and at the bottom of it?#2 Reverse question is this called split plate doubling or is it some thing else?Image588.jpgImage587.jpgThe highlighted areas ?

    The imperfections on the obverse are too small in your photos to draw any conclusions. The reverse shows a die crack and split plating doubling. "Split plate doubling" makes no sense as there is no "plate" involved.

      Thank's for the reply mike,I'AM confused are you saying the term split plating doubling makes no sense,or are you saying that me saying that makes no sense?Then if that's not the correct term for what's going on over the reverse letters what is? Please forgive me for being naive. I'am really trying to learn about the anomalies on coins and the correct terms and I greatly appreciate your knowledge you share me.Have a good one and keep up the good work .

        "Split plate doubling" makes no sense. "Split plating doubling" does.
