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

    Lamination Crack or Clad Layer Split

    Can someone give their thoughts on this 2020 Penny? There is a large piece of the top layer missing and I'm not sure how to define it. 20220527_232252.jpg 20220527_232310.jpg Fri May 27 23-06-29.jpg Fri May 27 23-06-56.jpg

    Looks like corrosion/staining. The cent coins are not clad, and they don't have laminations on zinc core coins. They do have the copper plating that appears to have been compromised on your coin. Most likely that something was spilled on it.
