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

    Double Die Crack Collection 1C 2017P rev

    Just as many doubling subjects as my bank box had, there are also double sided ribbon die crack subjects.

    And this is what every double ribbon crack subject has.

    looks for all intensive purposes to be weak secondary hubbing images due to a shift from pressure strength changing. (along the ribbon sides.)
