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

    This one has made the rounds in the other forums and one or two of you may even have taken a shot at it while there but I'm just stubborn and there's nothing anybody can do about it, and besides, I just love the look of this coin. I'm of course concerned about the marks on the image (...I can see the strike-doubling on the date and mintmark). If those impressions on the image are also related to the strike, I've just never seen that, before, in all those places...

    It's all machine doubling (slide doubling subtype).

      OK thanks Mike. I didn't picture it in a closeup but the "legs" on the RTY are also "pushed up" ever so slightly in the same general NW direction. I just hadn't noticed that when I took these pictures originally. Case closed on this one.
