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

  • 1985 100 Mexican Pesos Major Doubled Die

    One of my best variety finds ever. Was lucky enough to cherry pick a second of the same variety on ebay the same day that I discovered the first while hunting my foreign change jar at the start of the pandemic. (Getting an "unknown error" message when I try to upload the photos, so I've included an imgur link below).

      Ah, that explains it - noticed the site was down entirely yesterday. Glad to see it's back up! Thanks!

        very nice.

        i don't know why but i usually don't look at larger coins/denominations for ddo/ddr.

        it seems to me from past experience, i usually don't find them on larger coins/denoms.

        others have posted quite a few here and other places over the years.
