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

  • 1991d Lincoln Cent wide rim!

    This 1991d has a substantiality wider rim than the average penny. So much so that it balances itself with ease. Also the rim is the same thickness all the way around. I weighed it and came up with 2.6 grams when a normal zinc penny weighs 2.5 on my scale. Possible mule coin?or something else like no collar when struck? KIMG0161.JPG KIMG0159.JPG KIMG0158.JPG

    There are a few reasons for rim anomalies like this. They are misaligned dies, off center strikes, and finned rims. My guess is a finned rim and the weight is within specs. Sometimes a planchet is not rolled perfectly and will give the appearance of a thick or thin edge.
