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

  • 1984-D Lincoln Cent Overweight

    My first post to the CONECA Forum.
    This is a 1984-D Lincoln cent. The penny weighs 2.65 grams (as seen in the photo). The penny measures 19.03mm in diameter and it varies from 1.48mm to 1.50mm in diameter. Both of these dimensions are well within tolerance so the penny planchet is neither over-sized nor thicker than it should be. In truth it is slightly smaller in diameter and thickness yet it weighs more than it should. Is this weight within tolerances or is it possible this penny was minted on a planchet not intended for a penny? I have little experience with the weight of pennies and this is the first time I have found on that seems to be out of tolerance (after weighing thousands of them).

    The weight is within tolerance. It may indeed be struck on a slightly thicker planchet. Since the diameter of yours measures 19.03mm, it is .03 larger than designed, but whether or not that corresponds to the .15 gram weight increase is unknown. Being that all numbers are so close to normal, I would say that this coin is within specs.

      Thanks Bob. This is the first one I've run across that seemed heavy. I had a difficult time finding any kind of tolerances allowed on the internet. Thanks again, back into the recycle bin it goes. Someone else can spoon over this one.
