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

  • 1952-D Lincoln Cent CONECA: RPM-015

    I have a few of these 1952-D Lincoln Cents, and on the original 2x2 mylar it mentions a "D" near the rim.

    It took me a little while to locate a reference for this coin. Its one of the few Lincoln Cents I have that is way out of the typical mint mark placement area.

    I love the RPMs and OMM errors that are dramatic. The RPM's are pretty much dwindling down on the availability of RPM's.
    I have thousands of BU RPM's that range from 1944-D to 1972-D.
    Eventually these will increase in value, since they have not been produced since the mid 1990's or so.

    Unsure if it is mechanical/machine/strike doubling or damage? I suggest reading this post below !
