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

    Is it possible for a number to be missing in the date like this 1943 with a mising 4...It is completly gone..There is no sign of grinding or anything else..1943.jpg

    This is rather common on 1943 cents. While it's ordinarily attributed to die fill clogging the corresponding recess in the die, an enduring mystery is why this digit is affected so much more often than any other design element.
