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

    1990 Lincoln DDR? Rim damage and die crack

    IMG_20240611_174907.jpeg This 1990 penny is in great shape but has some damage. It looks like rim damage due to misaligned strike which might have created. What looks like a DDR. Also see a crack. What do you think? IMG_6077.jpeg IMG_6078.jpeg IMG_20240611_174822.jpeg IMG_20240611_174934.jpeg IMG_20240611_174917.jpeg IMG_20240611_174934.jpeg IMG_20240611_174907.jpeg

    In my opinion, the area that is showing blue in color is actually called split plating damage. This damage is caused when the strike is a bit too strong and damages/penetrates the top copper layer, exposing the zinc core.

    Die cracks happen quite frequently and unless they are super-dramatic usually do not bring collector interest nor any additional value.

      Thank you, Gary for the detailed explanation. I appreciate it. I am new to collecting so I don’t know what is a value increasing error and what isn’t yet. I am I’m concentrating on learning as much as I can on how coins are damaged.
