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

    The only one who can answer that question is James Wiles since he is the one who has the CONECA files.

      All I see in the photo is machine damage doubling. Not an RPM.

        David - I would also like to point out that it is not 1988D-1MM-012 either, the mint mark is way to low on your example. I also agree with James that this is machine doubling and not a re-punched mint mark.

          I don't see any notching where there should be and the doubling, though extensive, appears flat - which is normally attributed to machine doubling. Is there other evidence as well that I missed?
