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

  • Dryer Coin ? Die Adjustment Strike?

    When I bought a collection back in September 2016, it had Lincoln cent DDO's, DDR's, RPM's and a few odd ball coins.

    In the back of one of the binders there was this coin in a flip, unlabeled.

    It feels a bit smaller diameter wise compared to other wheat cents. When handling this coin, the rim is extremely high on the obverse and the reverse. Its very noticeable.


    The obverse photo below shot at about a 45 degree angle. I am trying to show the depth of the rim, focused at LIBERTY.

    Try as I may to take the same critical angle was frustrating, but here is a shot at the reverse, focused at EPU.

    Here is a shot of the rim, it looks pretty normal. It might have a slight curving towards the rim. The camera didn't behave and the camera flash fired, which contributed to a bit too much light.

    Full Reverse:

    The ISO was set too high in these photographs, so I used a program to reduce lighting equally across the entire coin. I did it a little more on the full obverse and full reverse, and it might show some tell tale signs of what this coin might be.

    My first thought was that this planchet was struck extremely hard, probably twice as deep as it was supposed to be set at. It looks like there might be some slight elevation in the devices around the rim, especially on EPU and IGWT.

    It could be a planchet that was abnormally thicker than most planchets, but on a scale the coin weighs 3.0 grams (scale only shows tenths of a gram)

    All comments welcome.
