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

    Possible clash marks?

    image_17342.jpg image_17343.jpg image_17344.jpg The marks on the obverse of this coin look like railroad tracks which may indicate a clash. I know that this in not uncommon as I have seen them before. Searches on the internet did not help at all. I researched collar clashes but was confusing. I would like to know if these marks are indicative of an error.

    The circular marks were caused by a coin wrapping machine. This is just post mint damage.
