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

    Discovery to make known: Proof Bicentennial 25c Double Die Rev.

    Hello everyone,

    I'm new to the forum. I've made a numismatic discovery and would like to bring it to the attention of the community. It is a Bicentennial Quarter with a double die reverse. I would like some kind of advice on what I need to do or who I need to show this to so I can have this find professionally validated and get a possible appraisal. I have not seen it in any books. The most prominent doubling is in the small side of the drummer's face and the lettering around the coin, "United States of America" and "Quarter Dollar". Any help in this area would be greatly appreciated. I have been collecting coins for several years in the past as a child and have just recently became more active as an adult collector. (the squiggly line in the second photo is a hair.)

    Hello Hobub,
    I hate to be the bearer of bad news but from the images I see here, you have a great example of strike doubling, ejection damage doubling, machine doubling damage or any of the other terms indicating NOT a doubled die. It is a great example that should be held for educational purposes. It has no premium. Sorry about that.

    Mike
