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

    I have a 1917 1 cent wheat penny only 0,79 mm thick

    This 1917 wheat penny weighs 1.3 g Dia. is 17.96 mm and thickness is 0.79 mm. The obverse is blurry, the reverse is a bit more clear. Could this be a split planchet? IMG_20240302_180747.jpg IMG_20240302_180632.jpg IMG_20240302_180827.jpg

    In my opinion, it looks heavily pitted.
    It could have easily been in the ground for a good length of time.

    It could also have been exposed to an acid based chemical. The acidity simply eats away all the features where the acids reside. This usually leaves the coin looking mushy and ghost-like.

    Either issue mentioned above can significantly reduce the weight of a coin like a cent.
