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

    1986D 50C mintmark

    Note the drag lines 90° of the 180° of the loop in "D" in the magnified picture and the notches in the top edge of the "D", as well as, it's tilted. Is this a RPM or punch bounce/drag? Other than that it is a nice full strike in inscriptions and date with minor bagmarks in the prime/secondary focal areas.

    yes, looks like bounce or drag. i'd lean towards drag aka ejection doubling but that is just my opinion.

      I agree, it looks as if the coin after the strike, the die lifted just a tad to the northwest and sheared part of the devices.

      Its vital to remember, that the working die is incused. It strikes the coin, and the mintmark on the working die is a little hole in that working die. Metal has to be squeezed into that hole and then the working die can shift just a tad as the working dies separate and it can shift ever so slightly and damage the coin. That's about the best I can explain worthless doubling.

      Things incused on the working die are raised on the coin.

        It looks like MDD (Machine Damaged Doubling), you can also see that doubling on the 9, 8, and D of GOD.
