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

    1983 Lincoln NGC MS63 RB cert overweight planchet weighs 2.98 grams

    Has anybody seen a copper plated Lincoln Memorial zinc penny that weighs 2.98 grams?? NGC states the copper plating to zinc core balance is 61%/39%. How could this happen to begin with? A normal copper plate 1983 should weigh 2.54g+/-. It's a huge jump up to 2.98g.

    Trying to establish a fair value. This coin has more than a few coin savvy people scratching their head. Any help would be appreciated!

    The answer is simple. Those sheets of zinc are not perfect, they are pressed between rollers and they can be either in tolerance or too thick or too thin at times. The planchets are punched out of those strips of metal, and eventually sent to the upsetting mill then up to the minting presses.

    CONECA staff frowns on providing values for coins since its typically something that the seller and buyer typically agree on. Prices can change dramatically from one person or region to another.

    It's an average condition. Most mint errors come out as that grade. To me, in my opinion, it's an error, but I do not see many people collecting these. I've never been asked if I have one for sale, nor have I ever seen or heard anyone selling one of these.

    In my opinion, it is worth a lot less than the grading, examination and shipping fees that were paid for when this thing got certified. If you want ball park values, check some high end auction houses for overweight planchets.

      I agree with Gary.

      I suggest you post it to the NGC.com/resources/chat boards/newbie forums and see what the boys there think about + or - value.
