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

  • 1958D Washington Quarter(ddo?)

    I wasn't able to find a listing for this one but it looks like there's doubling on the date. And maybe on I.G.W.T. Also was wondering about type B reverse. Something to do with A touching leaf and arrows touching leaves. Not to sure just thought I'd ask.

    This is where research can help. Knowing how the coins are made, the differences between hub and machine doubling, and the diagnostics of transitional or design changes will help in the long run. There are many articles on how to tell what a type B reverse looks like on the Internet. Just go ahead and search it.
    I included a link for a type B reverse search below. If we tried to explain it here, it would take forever.

      Thank you I've been reading about the minting process. I find it pretty fascinating.
