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

      I would agree with you now I see what it is thank you for the post where do you get these photo explanations? I would like to know so I to can reference my curiosity and be correct in my wanting to know what I have so I don't waist time on such little things and know when I have the real deal the one coin we all hope to find that will change our lives this coin hunting is so cool I only wish I would have started this journey sooner this is by far the one thing I find I really enjoy.

        Check out the posts in my signature. Some of them may help. Especially the one on mechanical doubling.

        I also suggest visiting https://doubleddie.com and reading the section on worthless doubling. John Wexler did a side-by-side explanation of doubled dies vs worthless doubling.
