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

    They give a description on where the doubling occurs.
    Proof coins have a PR desgination in the numbering system.
    Since you have the coin in hand, you may be able to find an exact match.

    Proof coins are often struck more than once to bring out the best highlights of the coin. Sometimes things happen and a coin gets a wierd strike. The difference between weird and a DDO/DDR is that the attributors have documented more than one doubled die that match up exactly.

    Going thru the proof quarters quickly, i did not see a match at Varietyvista.
