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 error/Damage 1967 penny

    • ​​I’m so confused I have gotten so many different answers on this from damaged to capped, stuck through foreign object to split planchette is there anybody that can help me. Or tell me what my next step is to figure out what exactly it is it is not scratched. It’s smooth to the touch just wavy and you can see a raised image of the memorial building IMG_5643.jpeg

    In my opinion, it looks like it could be a split planchet after the strike. All these planchets (blanks) are made of thin layers of metal rolled over and over until they are within tolerance. Some times there are impurities in the alloy mix that can cause issues that can cause the planchets to split, crumble or fragment. Its more on the uncommon side.

    The ODD thing about this one is, that the weight is very close to what a normal coin should weigh. With coin material lost, the coin suffering from split planchet affer strike should be considerably lower in weight (grams).

    Make sure your scale is accurate. Weigh several other Lincoln copper cents and see if they read close to the same (3.11g). The planchets can vary a bit in weight, so account for that.

    On this forum, there is a forum area called CONECA SERVICES. Under there is an area called EXAMINATIONS. The examinations area is for error coins. A CONECA staff member will look at the photos and determine if it is a legitimate error. Then, they will let you know if they want to see it in hand for closer examination.

    I do not know if there are any fees associated with these pre-screenings. They do the pre-screens in order to cut down the huge amount of clutter/non-errors and non-varieties they would have to look through. This is a volunteer organization and not a commercial entity. You may be able to find more info on the examination program at https://conecaonline.org
